– Olive
Leaf Extract –
A New/Old Healing Bonanza for Mankind
by
James R. Privitera, M.D.
INTRODUCTION
Science has long stalked
the chemical world within plants to uncover their amazing healing
secrets. Lately, these investigations have yielded discovery
after discovery of natural compounds with promising health
and medical potential.
Some of these compounds
stimulate the production of anti-cancer enzymes in the body.
Others bind and neutralize certain carcinogenic chemicals.
Other have antioxidant effects,protecting the body from oxidation
damage caused by harmful molecular fragments known as free
radicals that contribute to aging and illness.
These natural compunds
are found abundantly in roots, stems, leaves, fruits and vegetables.
They go by a variety of scientific names like polyphenols,
flavonoids, flavonols, pycnogenols, glucosinolates, isoprenoids,
carotenoids, tocotrienols and proanthocyanadins. To keep things
simple and pronounceable, we will just call them phytochemicals
or phytonutrients. Phyto stems from the Greek word for plant.
The volume of current
research is intense. Some experts say these compounds may offer
the best protection we know of against the diseases that plague
us today. There's much yet to learn about the tissue-specific
way they work. But with time, these phytonutrients, in the
form of supplements or medical preparations, may play a major
role in anti-aging medicine and how we prevent and treat disease.
Among the many phytochemicals
that have interested me, as a clinician, is oleuropein (pronounced
oh-lee-or-oh-pin), a substance found in the olive leaf. I,
as well as other health practitioners, have found that a natural
supplement of olive leaf extract contains substantial medicinal
benefits. Among them, boosting the energy among patients and
aiding in the treatment of herpes and other viral conditions,
flu and colds, fungal infections, chronic fatigue and allergies.
I have also been surprised by unexpected results generated
by this supplement.
The Olive Leaf in History and
Medicine
It is hard to avoid
the conclusion that there is something very special about the
olive leaf. For one thing, it is the first botanical mentioned
in the Bible.
"And the dove
came in to him in the evening, and lo, in her mouth was an
olive leafplucked off. So Noah knew that the waters were abated
from off the earth." (Genesis 8 : 11)
After the Great Flood
we didn't hear too much about the olive leaf for a long time.
Obviously this was a hard act to follow.
In a much later biblical
time (Ezekiel 47 : 12), God speaks of a tree: "The fruit
thereof shall be for meat, and the leaf thereof for medicine."
Was it the olive tree?
In Revelations, at
the very end of the New Testament, there is an angelic vision
of a "tree of life" whose leaves "were for the
healing of the nations." Today, as modern medicine increasingly
embraces phytochemicals it is interesting to speculate about
the biblical "tree of life."
Again, was it perhaps
the olive tree?
The ancient Egyptians
may be been the first to put the olive leaf to practical use.
They regarded it as a symbol of heavenly power, and in keeping
with that belief, they extracted its oil and used it to mummify
their kings.
Later cultures found
the leaf was better utilized for the living than the dead.
Over the ages, there is documentation that it was a popular
folk remedy for combating fevers.
The first formal medical
mention of the olive leaf - an account describing its ability
to cure severe cases of fever and malaria -- ocurred about
150 years ago. In 1854, the Pharmaceutical Journal carried
a report by one Daniel Hanbury and contained the following
simple healing recipe:
Boil a handful of leaves in a
quart of water down to half its original volume. Then administer
the liquid in the amount of a wineglass every 3 or 4 hours
until the fever is cured.
The author said he
discovered the effective tincture in 1843 and had used it successfully.
This method became well known in England for treating sick
Britons returning from His or Her Majesty's tropical colonies.
The author believed that a bitter substance in the leaves wasthe
key healing ingredient.
He was right.
Decades later, scientists
isolated a bitter substance from the leaf and named it oleuropein.
It was found to be one ingredient in a compound produced by
the olive tree that makes it particularly robust and resistant
against insect and bacterial damage. From a technical angle,
oleuropein is an iridoid, a structural class of chemical compounds
found in plants. It is present in olive oil, throughout the
olive tree, and is, in fact, the bitter material that is eliminated
from the olives when they are cured.<
In 1962, an Italian
researcher reported that oleuropein lowered blood pressure
in animals. This triggered a flurry of scientific interest
in the olive leaf.
Other European researchers
confirmed this interesting finding. In addition, they found
it could also increase blood flow in the coronary arteries,
relieve arrhythmias, and prevent intestinal muscle spasms.
Around this time, a
Dutch researcher determined the active ingredient in oleuropein
to be a substance he called elenolic acid. It was found to
have a powerful anti-bacterial effect.
By the late 1960's,
research by scientists at Upjohn, a major American pharmaceutical
company, showed that elenolic acid also inhibited the growth
of viruses. In fact, it stopped every virus that it was tested
against. Among others, the substance was found to counteract
a variety of viruses associated with the common cold of humans.
Moreover, a number
of laboratory experiments at this time with calcium elenolate,
a salt of elenolic acid, demonstrated a strong effect against
not just viruses, but bacteria and parasitic protozoans as
well.
The compound worked
effectively at low concentrations without any harmful influence
on host cell mechanisms, the American researchers concluded.
That meant they believed it to be extremely safe and non-toxic,
even at high doses.
Following test tube
experiments, the pharmaceutical company launched animal tests.
Experiments showed the compound was indeed extremely well tolerated.
There was a hitch, however. In the body of an animal, the substance
rapidly attached to protein in blood serum. For all intents
and purposes, this meant calcium elenolate was of no use. The
binding action essentially took it "out of action," rendering
it ineffective. As a result of this obstacle, research into
the compound as a potential virus and bacteria killing pharmaceutical
drug was dropped.
Nevertheless, research
and interest in olive leaf extracts has moved forward, primarily
in Europe. Among the most recent findings are these:
-
In a series
of experiments, oleuropein was found to inactivate bacteria
by apparently dissolving the outer lining of microbes.
-
At the University of Milan Pharacological
Sciences, researchers found that oleuropein inhibited oxidation
of low-density lipoproteins, the so-called "bad cholesterol" involved
in heart and aterial disease. This revelation, if confirmed
by further research, suggests that oleuropein may contain
antioxidant properties similar to other phytochemical compounds.
Medical researcher Morton Walker, D.P.M., writing about
olive leaf extract in the July 1996 issue of the Townsend
Letter for Doctors and Patients, comments that the intake
of flavonoids "is correlated with a lower incidence
of cardiovascular disease indicated that the daily intake
of olive oil and/or olive leaf extract containing phenols
will likely bring on a similar result." At the present
time, the cardiovascular research community is excited
about such actions. Studies have shown that some phytochemicals
can reduce the harmful oxidation of cholesterol as well
as slow down the accelerated clumping of blood platelets
that can lead to dangerous clots.
-
At Spain's University of Granada, pharmacologists
determined that olive leaf extract causes relaxation of
arterial walls in laboratory animals. Such results suggest
a possible benefit for hypertension, an effect first mentioned
by researchers more than 30 years ago.
-
In Tunis, researchers found that aqueous
extract of olive leaves reduced hypertension, blood sugar,
and the level of uric acid in rodents. This finding again
indicates potential in the treatment of hypertension, as
well as diabetes and heart disease. An elevated uric acid
level is a risk factor for heart disease.
Remember the biochemical
snag mentioned earlier -- that elenolic acid binds with proteins
in the body to nullify any therapeutic use? The problem has
been overcome and the door opened for the development of effective
olive leaf extract supplements.
Such products are now
available, containing oleuropein and synergistic olive leaf
extracts, including flavonoids.
The medicinal firepower
is there.
The safety is there.
The added benefit of
other phytochemicals is there. In short, we now have an exciting
new herbal with a promising future.
Olive Leaf Firepower
For the record, the
researchers at Upjohn found calcium elenolate effective in
test tube experiments against the following viruses: herpes,
vaccinia, pseudorabies, Newcastle, Coxsacloe A 21, encepthlomyocarditis,
polio 1, 2, and 3, vesicular stomititus, sindbis, reovirus,
Moloney Murine leukemia, Rauscher Murine leukemia, Moloney
sarcoma, and many influenza and parainfluenza types.
They found it effective
against these bacteria and parasitic protozoans: lactobacillus
plantarum W50, brevis 50, pediococcus cerevisiae 39, leuconostoc
mesenteroides 42, staphylococcus aureus, bacillus subtilis,
enterobacteraerogenes NRRL B-199, E. cloacae NRRL B-414, E.
coli, salamonella tyhimurium, pseudomonas fluorescens, P. solanacearum,
P. lachrymans, erwinia carotovora, E. tracheiphila, xanthomonas
vesicatoria, corynesbacterium Michiganese, plasmodium falciparum,
virax and malariae.
The researchers credit
a number of unique properties possessed by the olive leaf compound
for the broad killing power:
-
An ability
to interfere with critical amino acid production essential
for viruses.
-
An ability to contain viral infection
and/or spread by inactivating viruses or by preventing
virus shedding, budding or assembly at the cell membrane.
-
The ability to directly penetrate infected
cells and stop viral replication.
-
In the case of retroviruses, it is able
to neutralize the production of reverse transcriptase and
protease. These enzymes are essential for a retrovirus,
such as HIV, to alter the RNA of a healthy cell.
-
It can stimulate phagocytosis, an immune
system response in which cells ingest harmful microorganisms
and foreign matter.
The research suggests
that this may be a "true anti-viral" compound because
it appears to selectively block an entire virus-specific system
in the infected host. It thus appears to offer healing effects
not addressed by pharmaceutical antibiotics.
Clinical Perspective
Clinically, the olive
leaf extract has been used for a relatively short time. Health
professionals began using it early in 1995 when it first became
available. Although we do not have long-term perspectives as
yet, initial results are very positive. We see a very promising
and unique herbal with multiple applications. It shows considerable
therapeutic action against many common conditions. In short,
it appears to be living up to its unique background and expectations.
From research and clinical
experience to date, we can say that supplemental olive leaf
extract may be beneficial in the treatment for conditions caused
by, or associated with, a virus, retrovirus, bacterium, or
protozoan. Among such conditions are influenza, the common
cold, meningitis, Epstein-Barr Virus (EBV), encephalitis, herpes
I and II, human herpes virus 6 and 7, shingles, HIV/ARC/AIDS,
chronic fatigue, hepatitis B, pneumonia, tuberculosis, gonorrhea,
malaria, dengue, bacteremia, severe diarrhea, blood poisoning,
and dental, ear, urinary tract and surgical infections.
In our clinic, we use
olive leaf extract for a variety of infectious and chronic
conditions. We also believe that many people who lead stressful
lives or who may be particularly susceptible to colds and viruses
may benefit from long-term use of olive leaf extract as a preventive
agent.
As I mentioned earlier,
I am constantly surprised by unexpected benefits reported by
patients. This indicates that we are perhaps just scratching
the surface in our understanding of phytochemical benefits.
Patients have told me about improved psoriasis, normalization
of arrhythmias (heart beat irregularities), and less pain from
hemorroids, toothaches and chronically achy joints.
I myself cured a chronic
toenail fungal infection after starting on the supplement.
It had not responded to the many other nutrients that I take.
One woman with bad
allergies reported significant improvement and a level of energy
she hadn't felt for years.
One elderly male with
severe arrhythmia told me his condition had vastly improved
in about eight days just from taking olive leaf extract alone.
A woman with mild arrhythmia said her condition improved substantially
while she took the supplement and then slowly became irregular
again after she ran out.
We know from the oleuropein
research done in the 1960s that the substance improves blood
flood to the heart and acts to normalize arrhythmias. Currently,
we are learning much about the cardiovascular benefits of the
phytochemical compounds found in grape seeds, onions, kale,
green beans, broccoli, and other vegetables. It will be interesting
to see what benefits the particular phytochemicals in olive
leaf extract produce for heart and arterial health.
Phil Selinsky, a naturopathic
doctor at the Institute for Holistic Studies in Santa Barbara,
and biochemist Arnold Takemoto, who has been developing patient
nutritional programs on behalf of physicians in Arizona for
15 years, have found olive leaf extract to be an effective
addition to their array of natural healing tools.
After using the supplement
in dozens of cases for over a year, Selinsky is impressed with
the benefits and looks forward to continued use and greater
understanding about its most effective applications.
There is no doubt that
olive leaf extract has real healing power. In a moment I will
go into much greater detail on how it has helped patients.
It is important to
keep in mind, however, that like any nutritional supplement
it should not be considered a cure-all or panacea. In holistic
practices such as mine, individual supplements are part of
a comprehensive program that includes better diet, exercise,
and stress control methods. That's how we maximize health and
minimize symptoms.
In such a program,
a patient may start with supplement X, Y and Z, get involved
in an exercise program, and experience perhaps 50 percent relief
for a given condition. That's a lot of relief but then we keep
trying to improve the situation. We now add another supplement,
let's say the olive leaf extract, and we get another degree
of improvement, often quite large. In this manner, we continually
tailor the program of an individual patient for the best results.
And in this scheme of things, olive leaf extract is making
a very positive contribution. It complements all the good things
patients are doing.
There is always the
possiblity that one ingredient, one supplement, can fill a
large gap or particular need in the body and by itself lead
to major improvement. We see that happen all the time. But
usually it is all the elements in a nutritional program that
work together -- like a team of horses pulling a wagon -- that
gets the job done most effectively.
Biochemist Arnold Takemoto
puts it this way: "Olive leaf extract is not a single
magic-bullet. There are very few such things, especially in
non-pharmaceutical medicine. In many cases it takes a whole
lot more than just one ingredient to get over a particular
condition. Yet I find it a very valuable addition against chronic
fatigue syndrome and many other viral conditions, especially
those that are more tenacious. It fills a hole that we haven't
been able to fill before."
In the Townsend Letter
article, Takemoto told Morton Walker that he has "yet
to discover another herbal substance that accomplishes antimicrobially
what this substance achieves."
Takemoto went on to
say that Lisa Weinrib, M.D., one of the physicians he works
with, treats many cases of fibromyalgia and chronic fatigue
syndrome.
She has noticed that
patients with these problems exhibit much improvement from
use of the extract, according to Takemoto. "It's the missing
link that functions as an antiviral and antiretroviral agent
by slowing down the organism's reproductive cycle. A slowdown...allows
the patient's immune system to go on the attack."
Takemoto says olive
leaf extract has helped patients eliminate stubborn viral infections
they have had for years. One patient, who had suffered from
shingles (herpes zoster) for nine years, experienced complete
relief within two days of starting olive leaf extract and other
supplements.
"In my approach," Takemoto
says, "I target key antibody responses for specific viruses,
stimulate the immune system, and with olive leaf extract attempt
to inhibit the reproduction of the virus. It takes everything
to get over some of these real chronic conditions."
More Energy
One of the most frequent
comments we hear from patients after they start taking olive
leaf extract is that they feel more energetic and have a greater
sense of well-being. Many want to continue the supplement even
after the treatment program has cleared up or reduced specific
problems.
Some patients are energized
to the point that they inquire whether there is an "upper" in
the product. There is not. It simply generates a natural "upper" effect.
Healthy people who take it say they also feel this infusion
of energy.
One of my patients
is an 18-year-old professional ice-skater who says that one
or two olive leaf extract tablets a day helps her sustain the
high energy level she needs for practice and performance.
In my clinic, as in
many others, fatigue is the No. 1 complaint. I am not refering
to serious chronic fatigue situations but just routine tiredness,
likely caused by a combination of consuming a dead food diet
and not exercising. The average person, of course, is not going
to change eating habits and is not going to go on a regular
exercise program. In such cases, the olive leaf extract looks
like a good source of pep for the pepless.
Chronic Fatigue
In my experience, olive
leaf extract also has helped in many chronic fatigue cases,
even the most serious. One female patient described to me what
she called a "really quite unbelievable" recovery
within one month of taking the supplement.
"For the last
few years I have not been feeling like myself. I've had little
energy and enthusiasm for anything. This is not my usual nature.
I attributed it to weight, unemployment and just being down.
My head was always somewhat achy and I couldn't figure out
why. The only way I could describe it would be as a constant
low-degree headache which never left.
"I started taking
olive leaf extract and noticed an immediate elevation of my
spirits. What I liked about the product was that it was effective
but gentle and didn't make me hyper or unable to sleep. Quite
the contrary, I slept better.
"After a few days
I began to notice more energy and a stronger sense of well-being.
The cobwebs in my brain started to diminish. I also noticed
a bad shoulder and a bad knee started to get better. The pain
associated with these joints remarkably improved.
"The only side-effects
I had were a couple of headaches in the beginning which disappeared
with some aspirin. I started to feel much, much better. It
was amazing to see the fatigue disappear and my general health
improve. I couldnít believe I felt so well. I stopped
taking the product after 30 days and experienced no withdrawal
or anything. I simply felt better and that has stayed the same
for the last 60 days without the product."
Another female patient
with Epstein-Barr Virus reported that the supplement "has
helped me very much in overcoming the tiredness I feel. It
has given me energy."
For some very sick
individuals, including people with chronic fatigue syndrome
or particularly heavy loads of virus or bacteria in their bodies,
olive leaf extract may possibly generate detoxification symptoms
-- known as the "die-off effect" -- that may be unpleasant.
Such people may actually
feel worse for a short time before feeling better. As an example,
many chronic fatigue patients suffer from an associated depression.
Patients of mine who toughed it out through the"die-off" period
emerged highly energized and no longer depressed.
The "die-off effect," or
Herxheimer Reaction as it is medically called, refers to symptoms
generated by a detoxification process. If you are sick and
use this product, you should be aware of the possibility. For
this reason it may be advisable to consult first with a holistic
health practitioner before using it.
If you have ever used
Nystattin to fight yeast infections, you are probably familiar
with this situation. Nystattin kills yeast. As the body becomes
full of dead yeast, you may experience a variety of detox symptoms.
Symptoms may intensify to the point where you need to stop
or reduce the dosage of the medication in order to give your
body a chance to eliminate the toxic waste.
Olive leaf extract
is potent stuff. It can generate an internal cleansing action
that may similarly cause significant detox symptoms. Refer
to the next chapter about what to do if you experience such
a reaction.
"Die-off" Effect
"Die-off" symptoms
can begin almost immediately after starting the supplement.
It can hit different people in different ways. Reactions include
extreme fatigue, diarrhea, headaches, muscle/joint achiness
or flu-like symptoms. Severity differs also from person to
person, depending on the extent of infection.
Keep in mind that such
symptoms are positive signs. Nevertheless, they can be unpleasant.
Some people may not want to continue because of the discomfort.
Others handle it better. Others experience no such effect.
Here's what to do in
case of substantial detoxification symptoms:
-
Reduce
the number of tablets, or even stop them altogether for
a while.
-
You may need a day or two, or even a week,
to allow your body to process the "die-off."
-
When you feel better, you can resume the
supplement at a low dose and increase slowly.
-
Holistic practitioners can usually provide
a supportive detoxification program for individuals who
experience a strong "die-off" response. In my
clinic, this program includes taking vitamin C to bowel
tolerance. Such a regimen is best done under professional
guidance.
-
Other than the "die-off" detoxification
effect among some individuals, olive leaf extract appears
to create no side effects. Past research with calcium elenolate,
the derivative or oleuropein, included safety studies with
laboratory animals. They were dosed orally and also via
injection. The only symptom observed was a mild irritation
of the mucous membrane among some animals at the injection
site. Since olive leaf extract is taken orally, this observation
is basically irrelevant.
The research indicated
that doses many times higher than recommended are unlikely
to produce toxic or other adverse side effects. During 1993
testing of the liquid form of the product against the herpes
virus, there were no observed or reported side effects.
Potential Against Serious Infectious
Diseases
Deaths from infectious
diseases, formerly on the decline, have recently taken an alarming
upward turn in this country.
According to federal
researchers, such deaths rose by 58% from 1980 to 1992, pushing
this category of illness up behind heart disease and cancer
in the No. 3 spot of killer diseases.
While the AIDS epidemic
accounts for most of the rise, experts say there has been an
unusual increase in mysterious respiratory infections among
the elderly and blood infections among people of all ages.
When you eliminate the AIDS the death rate during the same
period for all other infectious diseases rose by 22 percent.
The World Health Organization
(WHO), back in 1978, looked to the future and issued a report
which contended that by the year 2000, sources other than Western,
technological medicine would be needed in order for all people
to have adequate health care. The organization subsequently
adopted the report that recommended the use of traditional
forms of healing and medicine, such as the use of herbs, to
meet the demands of an factor, exploding global population.
As we approach the
year 2000, the wisdon -- and the urgency -- of this advice
is obvious in the light of the serious side-effects and shortcoming
of pharmaceutical drugs.
With the emergence,
for instance, of antibiotic-resistant bacterial strains, natural
products such as olive leaf extract take on greater importance.
Even if new antibiotics are developed, new infectious bacteria
would emerge that are resistant to new drugs. In the case of
herbal medicinals, their complex chemistry may often render
them potentially more effective against a wide variety of microorganisms
for which pharmaceutical drugs prove to be ineffective.
AIDS
It will be interesting
to see if olive leaf extract can benefit AIDS cases. We know
that it inhibits the production of reverse transcriptase and
protease, enzymes necessary for certain viruses, such as HIV,
to damage healthy cells.
Informal, preliminary
reports are promising.
Mark Konlee, editor
of "Positive Health News," a newletter on alternative
treatments that circulates widely in the AIDS community, has
reported exciting initial results with olive leaf extract,
either in the tablet supplement form or directly as a tea brewed
from leaves, in combination with other ingredients.
Those other ingredients,
according to Konlee, have been found to be highly beneficial
over the years. They include:
-
Naltrexone,
an immune-stabilizing drug used in the treatment of heroin
and alcohol addiction. Clinical trials conducted by Bernard
Bihari, MD, a New York City physician specializing in
HIV/AIDS, demonstrated that this preparation stops the
progression of the disease and the decline of the immune
system in a majority of patients who take it regularly.
Naltrexone stimulates key hormones regulating the immune
system and the communication between the brain and immune
function. No side effects have been reported.
-
DNCB (dinitrochlorobenzene), a chemical
used in photography labs that is applied in small doses
on the skin. This compound acts as anti-viral agent by
stimulating killer cell activity. An estimated 7,000 patients
with AIDS have used this substance for some 10 years.
-
A blend of olive oil/whole lemon juice.
This "grassroots" recipe appears to be uniquely
helpful in reversing neuropathy, swollen lymph nodes and
wasting syndrome associated with the HIV.
For more specifics
on this approach, interested individuals may contact "Keep
Hope Alive," P.O. Box 27041, West Allis, WI 53227, or
by phone at 414-548-4344.
Konlee reports that
the combination, with added olive leaf extract, "has producted
stunning results," including viral loads dropping dramatically
within a month. Among the cases he describes are these:
-
A patient had been using Naltrexone since
October 1995 along with weekly topical applications of
DNCB. He had not used the olive oil/lemon juice blend.
In August of that year he had had a CD8 count of 700. CD8
refers to killer T cells, which, along with so-called Natural
Killer cells, are major immune destroyers of virus infected
cells. They reduce viral loads and inhibit damage to the
body's defenses.
In January of 1996, his CD8 count had risen to 1380. In March of 1996
he added olive leaf extract at the standart dose of one capsule four
times daily. He initially experienced a mild headache, a probably "die-off
effect." Within days, he reported a significant increase in energy
along with the disappearance of swollen lymph nodes. He said he felt
20 years younger. On March 21, his CD8 count had soared to 1920! His
physician said never before in his career had he seen such improvement
in an AIDS patient.
-
One patient reported that after finishing
a bottle of olive leaf extract, one of three Kaposi Sarcoma
lesions on his chest vanished. He experienced headaches
and flu-like symptoms for about two weeks, again a probable "die-off
effect." Continuing with a second bottle, he said
the second lesion was completely gone and the last one
was "fading fast."
His HIV viral load, as measured by PCR technology, had dropped from 160,000
to 30,000 in two months. Soon afterward, he reported that his PCR results
for HIV were now down to 692.
-
An HIV patient reported his genital herpes
vanished within four days of starting on the olive leaf
extract.
-
Another patient with Kaposi's Sarcoma and
retinitis added five capsules of olive leaf extract daily
along with Naltrexone and DNCB. After doing this, he said
that the sarcoma lesions stopped growing. This prompted
him to stop two drugs he had been taking -- Ganciclovir
and Biaxin -- because of severe intestinal side effects.
A few days after discontinuing the drugs, his digestion
returned to normal. He soon reported improved vision and
that lesions were becoming lighter in color.
-
One patient took the olive leaf extract
by itself for about 3 1/2 months. His HIV viral load dropped
nearly in half as a result, along with significant improvements
in his white blood cell counts. After adding Naltrexone
and the lemon/olive oil drink, his improvement accelerated.
Herpes
I have recommened olive
leaf extract to many patients with herpes. The results have
been encouraging.
One man in his early
40s suffered from repeated lesions plus fatigue. In a week
after starting the supplement, his lesions disappeared and
his energy level increased. He told me that olive leaf extract
was the only preparation that had ever cleared up the herpes. "Even
the most minute blisters are gone," he said.
A female patient had
an unusually stubborn herpetic cold sore in the mouth for four
months. She also suffered from cancer, thus there may have
been some significant immune exhaustion involved. After one
week with the olive leaf, the sore disappeared.
These and other similar
clinical successes are consistent with a private 1993 herpes
study in humans. In that investigation, a weaker and ethanol
(alcohol-based) form of olive leaf extract was used by six
individuals with herpes.
All reported symptomatic
relief.
Three said their lesions
disappeared within 48 hours. The remaining three, who experienced
no improvement, then received a stronger dose. One said that
three days later, most of the lesions were gone. The other
two also reported doing better.
All six subjects said
the olive leaf extract produced better results than Acyclovir,
a medication they had previously used.
Flu and Colds
Results to date indicate
that olive leaf extract may be a good weapon against the common
cold and flu. Consider the following letter written to me in
August of 1995 by a female patient suffering from persistent
flu symptoms:
"I became ill
with the flu in February and had several immune boosters, extra
vitamins and three antibiotics. My fever was 102-103 every
afternoon and this continued even after the antibiotics. I
developed paralyzing chest and abdominal pain, being confined
to the couch for weeks -- not able to hardly walk. My weight
dropped to 84 pounds. Medical tests revealed nothing specifically
wrong.
I started taking olive
leaf extract on July 18. Within a few days my temperature started
dropping and it is slowly and steadily going down, so that
some days I haven't needed to take Tylenol to reduce it. The
pain is subsiding gradually and my appetite and strength is
returning."
At the time of her
next medical examination, the woman's temperature had been
normal for a week. She hadn't needed pain-killers for two weeks.
I received a striking
testimony from an elementary school teacher with a history
of asthma and vulnerability to colds and flu. She felt that
olive leaf extract fortified her against the constant exposure
to germs circulating throughout her classroom.
"I used to get
sick all the time," she told me. "One school year
I got strep throat eight times. If you sneezed at me, the chances
are I would get sick. Not any more. When many kids in my class
were coughing, sneezing, and blowing their noses before Christmas,
I caught a slight cold and that's it."
Bacterial Infections
The ability of olive
leaf extract to destroy bacteria was demonstrated dramatically
in the case of a 64-year-old physician who had been bedridden
for several years following a serious stroke. He also had recurrent
bladder infections which caused considerable pain, smelly urine
and fever.
All efforts to alleviate
his condition had been generally unsuccessful. Even a $1,000
antibiotic specially made for him had not worked. He had constant
discomfort. His urine was cloudy "and looked like soup." Often
it was bloody.
After one month on
olive leaf extract, the infections had vanished. After six
months, the condition has not recurred.
The doctor also suffered
from frequent allergies and colds and had to take medication
to keep these under control. The incidence and severity were
significantly minimized with the supplement and as a result
he requires considerably less medicine.
Naturopath Phil Selinsky
reports success against bacterial infections in a number of
cases. These include sinus and bladder infections and oral
infections associated with tooth or gum disease.
"Some patients
have told me that olive leaf extract took down their dental-related
infections within hours," according to Selinsky. "They
were quite impressed by the response."
The general recommendation
for olive leaf extract is four tablets daily. For these kind
of infections, Selinsky recommends patients begin with two
tablets followed by another every four hours.
"That usually
gets you on top of the situation," he says. For more serious
infections, tablets can be taken at shorter intervals.
One night a patient
of mine developed swelling and intense pain from an abscess
and decided to take several tablets at one time. It reduced
the pain. In the morning, when the pain returned, he took a "handful" of
tablets -- about eight or nine, he guesses. An hour-and-a-half
later, the pain and swelling were gone. The pain did not return
but a dental examination determined that the involved tooth
had to go.
Diabetes
Researchers have found
that the natural olive leaf compounds can decrease the level
of blood sugar. I have had several cases in my clinic confirming
this finding.
One involved a 15-year-old
girl with juvenile diabetes. The teenager had been regularly
taking 350 units of insulin daily for control. After one month
on olive leaf extract, she was able to maintain similar control
with just 220 units.
In another case, the
blood sugar level of a diabetic elderly priest dropped from
450 to 160 after three months. In an yet another instance,
the blood sugar of a middle aged man stabilized at 140, down
from 250, after one month. He reported a great increase in
energy during this time.
These results are exciting.
I look forward to more opportunities to gauge the benefits
of olive leaf for diabetics. Will it generate improved blood
flow and antioxidant effects to help against the destructive
vascular complications of diabetes that contribute to stroke,
heart disease and peripheral circulatory problems?
Time will tell.
Rheumatoid Arthritis
A number of patients
have experienced significant easing of joint pain. We don't
know yetprecisely how this is happening.
A male patient, who
had been diagnosed with rheumatoid arthritis five years before,
had this to say: "After taking all the medicines I could
stand with no real results, I was informed about some nutritional
supplements. One of them was an olive leaf extract.' "After
taking it for three weeks I noticied more flexibility in my
fingers, elbows, and neck. There was marked relief of muscle
tension surrounding my joints. Overall I am enjoying olive
leaf extract with my daily routine."
Multiple Symptoms
One of our clinical
observations is that olive leaf extract appears to work on
many different levels in the body. As a result we often hear
reports from patients that a variety of symptoms begin improving.
One woman with chronic
fatigue, frequent colds, asthma, and vaginal yeast infections
said that all her symptoms had virtually cleared up within
five weeks. The woman, a teacher, was able to take on new projects
she wouldn't even begin to think were possible before.
A male patient wrote
a detailed letter about his experience:
"I became ill
in December 1993 and was diagnosed with a stomach and prostrate
infection. I was treated with high doses of antibiotics, but
never fully recovered. I was troubled with multiple symptoms,
some of which were back and neck pain, fatigue, flu-like symptoms,
swollen glands, sinus and digestive problems. I was subsequently
diagnosed with fibromyalgia (chronic fatigue syndrome) and
the physicians recommeded Prozac-type antidepressants and anti-inflammatory
drugs. But I refused them. I began taking olive leaf extract
along with my regular vitamin and mineral supplements in August
of 1995 at the rate of one tablet every six hours. I increased
the dosage after five days and began to feel better."
"I tried different
dosages for a number of days until I found the optimum amount
for me. Today I take three tablets four times a day. My overall
health has greatly improved and so has my energy and disposition.
One very interesting thing has occurred. My finger nails were
infected, by whatever infection I had, leaving them wrinkled
looking. Now they are slowly returning to their normal shape."
A female patient, after
taking olive leaf extract for a month, gave me this happy report:
"It has improved
my allergy-like psoriasis, and symptoms of a kidney infection.
I have been having back aches for almost a year and frequent
urination. These have improved a lot also.
Fungus and Yeast Infections
Earlier I mentioned
my own positive experience with olive leaf extract. I started
taking the supplement and it completely cleared up a stubborn
toenail fungus infection. A number of other patients have told
me similar stories.
A woman with an infection
of the large toenail said that within 60 days her condition
was about three-quarters healed. For five years, she had tried
many types of medication and natural agents without help.
More than 10 million
Americans are said to have disfiguring fungal nail infections,
a widely ignored medical problem. It is frequently found among
patients with AIDS, cancer and diabetes, athletes, elderly
individuals, people who spend considerable time standing or
who wear the same shoes day after day, or who wear artificial
fingernails. Drugs taken for cancer and AIDS lower resistance
and are believed to make people more susceptible to infection.
For the first time
in 35 years, a new drug has been approved for the condition.
It is called Sporanox and is reported to be more effective
than previous anti-fungal preparations. But none of these preparations
come cheap. Patricia Anstett of the Knight-Ridder Newspapers
reports that two 100-milligram pills of Sproranox are taken
daily for about three months at a cost of $900. Older drugs,
taken for 12 months or more, cost double or more that amount
over the longer duration. Even with the new drug, the condition
may return if the medication is stopped.
Olive leaf extract
may offer a natural -- and for sure, less expensive -- method
of self-treatment.
One patient said a
fungal infection of the tongue he had for 30 years responded
virtually overnight to the olive leaf. "I had tried all
kinds of diets, treatments and regimes but to no avail," he
told me. "Within three weeks on olive leaf extract the
fungus disappeared!"
More than a dozen patients
with candidiasis have reported significant improvements. They
say they have fewer infections, allergic reactions, less dullness
and more energy. One woman said she was finally able to clean
out her dust-ridden garage. Before olive leaf extract that
would have been impossible for her.
One 36-year-old woman,
who had suffered repeated vaginal yeast infections for several
years, told me this account of her experience with olive leaf
extract:
"I have seen several
doctors using conventional medicine. They prescribed every
medication available to combat yeast, all to no avail. After
less than three weeks of taking the olive leaf supplement,
all symptoms cleared up and have not returned. As a sufferer
of herpes simplex II, I would experience outbreaks several
times a year. Now, I have had no more flare-ups."
Skin Conditions
A chronic scalp infection
that had stubbornly resisted all treatment for more than 10
year responded directly to olive leaf extract within 60 days.
The patient wrote me this detailed letter:
"The condition
would flare up causing very painful eruptions and lesions in
my scalp, which, over time, have killed quite a few hair follicles.
Modern medical doctors and dermatologists have been unable
to eradicate (the condition). I had resolved my self to the
fact that there was no cure.
"I am satisfied
that I am getting some significant results from using the olive
leaf extract. My scalp remains a little tender, but the eruptions
have all but ceased. I am continuing to use the product about
twice a day, and the skin color is much healthier than it has
been in recent time.
"No matter what
drug therapy my doctors have prescribed in the past, none has
provided me with the level of relief I am currently experiencing.
I would gladly recommend this product to others suffering chronic
skin aliments."
A female patient reported
better energy and disappearance of a rash in 30 days. The rash
occurred in winter, or during times of extreme cold.
Tropical Illnesses
Olive leaf extract
may offer considerable potential in the treatment of tropical
infections such as malaria and dengue.
Malaria is caused by
parasitic protozoans injected into the body by infected mosquitoes.
Protozoans, in case you are interested, are one-celled organisms,
the simplest creatures in the animal kingdom.
As far back as 1827,
reports have appeared in medical literature indicating the
benefits of olive leaf extract in the treatment of malaria.
In 1906, one report stated that olive leaves were, in fact,
superior to quinine for malarial infections. Quinine was preferred,
however, because it was easier to administer. In studies performed
by the Upjohn company, calcium elenolate, the substance within
oleuropein, was found to be effective against the malaria protozoa.
Now in tablet form,
there may be renewed interest in olive leaf extract as an anti-malarial
agent. Preliminary reports from Latin America are promising.
A full-fledged case
of malaria at a clinic in Mexico was totally cured with a dosage
schedule of two olive leaf extract supplements every six hours.
A clinic report said that the 34-year-old female patient made
a steady recovery and after six months, "she was without
any of the malaria symptoms, not even anemia or shivers. Her
breath is good. Her state of mind excellent and she does not
show any signs of chronic or contagious disease."
Malaria has been reported
recently in Texas and continues to be a leading cause of illness
and deaths worldwide, particularly because of the development
of drug-resistant strains. "It is a continuing concern
in the United States because of increased international migration,
travel, and commerce, " according to the publication Morbidity
and Mortality Weekly Reports.
Another serious tropical
disease giving concern to public health officials is dengue
fever. This ailment is also mosquito-borne, in this case caused
by a virus, and occurs mainly in tropical Asia and the Caribbean.
It can cause vomiting, high fever, loss of appetite, and abdominal
pain, and is deadly in 50 percent of the cases. Some 50 million
people are affected each year and about half a million require
hospitalization, according to the World Health Organization.
Researchers are trying to find a vaccine but no breakthroughs
have occurred yet.
In 1995, large outbreaks
of dengue were reported by health authorities in 12 Latin American
and Caribbean countries.
Dosages
Olive leaf extract
is currently available in the form of 500 mg. tablets. The
routine dosage is one tablet every six hours or four throughout
the day. Take the supplement between meals for best results.
In the case of bad
colds or flu, you can use two tablets every six hours. For
acute infections, some individuals have taken more -- three
and even four every six hours -- and reported rapid relief.
If you encounter a "die-off" effect,
cut back on the number of tablets you are taking or temporarily
discontinue them. See the section on "die-off effect."
For healthy folks seeking
more energy or the prevention benefits of olive leaf extract,
we suggest one or two tablets a day. The younger and cleaner
the body, the more responsive it is to supplements such as
this. When a person becomes older and more toxic, more of the
supplement is required to do the job.
