Getting a Grip on Pain:
Documenting the Facts on Emu Oil and
Arthritis
"The dramatic results I have
observed convinced me that this oil can make an impact on those suffering from
arthritis" - Dr. Thorn Leahey
American emu producers may soon
have some solid proof by which to support some very old beliefs concerning emu
oil. A clinical study, to be conducted by Dr. Thorn Leahey of the Arthritis
Clinic in Ardmore, Oklahoma, is currently being planned to determine what effect
emu oil has on hands plagued by arthritis. A preliminary study has already
produced some positive indications that the oil may substantially reduce the
pain caused by arthritis. "We took a random sampling of 20 volunteers for a
double blind, placebo-controlled study using emu oil and mineral oil," said Dr.
Leahey. "The only qualifying parameter was that the volunteer could not have
ever used emu oil before the test. Volunteers also remained on the same
arthritis medicine they were currently taking," he explained.
"In this 2 week study, 7 of the
12 emu oil users reported a significant reduction in pain, morning stiffness and
swelling. Only 1 of the 8 mineral oil users (placebo) related the same results,"
reported Dr. Leahey. Encouraged by these preliminary findings, Dr. Leahey felt
the oil merited additional investigation through a comprehensive clinical study
that could be documented and published in scientific and trade journals.
The proposed study, which will
extend over a three month period, will involve 500 participants. "The main
qualifying factor will be that the participant must have had arthritis diagnosed
in their hands," he explained. Although the extensiveness of the arthritis is
not a factor that will disqualify a volunteer, Dr. Leahey maintains a personal
theory that the oil may have its greatest impact on early stages of arthritis
pain. "I don't know if any topical aid would be beneficial for chronic or
burnout arthritis, where the cartilage has been virtually destroyed. I suspect
the oil reduces inflammation around and within joints, and assists in allowing a
greater freedom of movement," he reasoned.
"This study will not only
provide for a subjective determination of the effect of the oil." said Dr.
Leahey, "but it will also include direct measurements. By using a dynamometer,
we can confirm changes in the participant's gripping strength. Also, by direct
examination of the hands, it is very easy to test the sensitivity and number of
tender and swollen joints," he revealed. Volunteers that are accepted and have
been off arthritis medicine for one month will receive an initial examination
measuring the gripping strength in the hands.
The subject may be asked at the
beginning of the study to assign a number corresponding to the pain level being
experienced in their joints on a scale of 1 to 5. After the hands are examined,
the subject will be instructed on how to properly apply the oil onto the hands,
tentatively 3 times a day for 3 months. The subject's hands will be re-examined
and evaluated at the end of each 30 day interval. "When I was initially
approached by patients advising me that they were experiencing relief from emu
oil, I did a literature search on the topic of emu oil and medical applications.
I quickly learned that there is a big void in this area and that there were no
published articles in scientific or medical journals," Dr. Leahey revealed.
Personal observation of the effectiveness of the emu oil on his own patients was
the motivating factor behind Dr. Leahey's proposal for a clinical study. 'The
dramatic results I have observed convinced me that this oil can make an impact
on those suffering from arthritis," he stated.
'The advent of this oil has
simply changed my practice," he asserted. Currently, the proposal and budget are
being written up for the project. Dr. Leahey is hopeful that the project may
begin as early as late July or early August. He noted that local physicians will
be made aware of the study and will be asked to assist in securing volunteers
for the study. Also, local newspapers and other media surrounding Ardmore will
carry advertisements soliciting volunteers. "The research is imperative," stated
Dr. Leahey. The initial results and potential are so exciting. In the last few
weeks, I've begun recommending the use of emu oil as part of a regular treatment
program for patients," he revealed. "I've observed some very surprising results.
The oil is very economical compared to regular arthritis medicines, and appears
to have fewer side effects," he continued. "It's very encouraging to find
something that may help relieve the suffering associated with arthritis, and
it's very exciting to be a part of a project that may impact the quality of life
for so many people."

Elusive Anti-Inflammatory Component of Emu Oil Isolated
"...even at full strength,
emu oil generated irritation levels so low, the results were comparable to that
of water..."
A newly-issued (1995) US
patent, "Anti-inflammatory Composition Derived from Emu Oil" has revealed that 4
inventors have isolated a yellow-colored component from emu oil that appears to
be the active ingredient responsible for the oil's renowned anti-inflammatory
activity. US Patent # 5,431,924 reveals that the inventors (all Australian)
describe experiments that they conducted with emu oil and with this yellow-colored
component to demonstrate the anti-inflammatory activity of the yellow component.
Of the 17 claims made In the patent, 3 of them cite compositions in the form of
oral, topical, and injectable compounds. The impact of this documentation on the
anti-inflammatory properties of emu oil has effects that reach far beyond emu
enthusiasts. Kristi Tomlin, registered pharmacist in Blackwell, Oklahoma,
acknowledges that the main problem with anti-inflammatories currently on the
market is their side effects. "The oral anti-inflammatories eventually cause
stomach discomfort and irritation, which in turn leads to other problems," she
reports. "For those able to endure this irritation, the next problem is that it
eventually stops working. The patient builds a tolerance for the medication,
leaving it ineffective."
Topical applications, too,
leave much to be desired. "Most of the topical applications which require no
prescription use an ingredient derived from a Mexican pepper. Although the
warmth it produces contributes to relief, the products often irritate and even
burn the skin," Kristi observes. Another method of delivery for anti-inflammatories,
the injectable form, is often used for severe cases. In addition to the
irritation caused to the blood vessels, one of the main deterrents for using
this method is consumer reaction. "Most people do not like the idea of getting
shots or giving themselves shots," revealed Kristi. "Patient compliance
diminishes considerably if there is an aversion to the method, frequency, or the
effects of a medication," she elaborated. Summarily, the majority of anti-inflammatories
on the market today produce side effects that are often so severe, the consumer
must weigh their benefits against their side effects.
However, in the case of emu
oil, laboratory irritation tests conducted by Emu Ranchers Incorporated in 1991
revealed that even at full strength, emu oil generated irritation levels so low,
the results were comparable to that of water In laboratory and clinical tests,
as well as marketing studies for new products, pure emu oil and compounds
formulated with it have generated surprisingly little irritation. Even current
research on the oral consumption of bacteria-free emu oil has yet to reveal
adverse side effects from oil use. A pharmaceutical grade of emu oil possessing
anti-inflammatory properties with minimal side effects could alleviate the most
pressing concerns regarding the use of anti-inflammatories in the medical
profession today.
The documentation of the patent
notes that the inventors have found that "emu oil deficient in linolenic acid is
highly active and secondly, emu oil contains other compound(s) which alone or
when combined with a transport enhancer provide an effective anti-inflammatory
composition." Further, this "biologically active yellow-coloured component may
be included In topical, oral and systemic compositions for the treatment or
prophylaxis of musculoskeletal and/or dermatological conditions arising from
inflammatory reactions of environmental or systemic origins."
One of the most interesting
observations noted in the experiments occurred when emu oil was exposed to
sunlight for several weeks. Upon examination, the oil appeared inactive when
tested for anti-inflammatory activity. However, this anti-inflammatory activity
was actually restored with the addition of retinyl acetate. Other findings
elaborated on within the patent "clearly identify the yellow components in emu
oil immuno-regulant activity, apart from their ability to modulate disease once
initiated." The patent displays table after table of experiments conducted with
other oils, fats, and compounds used and readily available on the market today.
Allen Strickland, pharmacist in
Ozark, Alabama, summarized the three aspects of the invention as (1) a
pharmaceutical composition that acts to provide effective transport across the
dermis or mucous membranes; (2) a method of treatment; and (3) the process by
which the biologically active yellow-coloured component is extracted from the
emu oil. According to Strickland, the published documentation in itself will be
a valuable sales tool. "It's a lot easier attract the interest of a
pharmaceutical company when you have this sort of research to support your
product," he reflected. "Pharmaceutical companies devote persuasive reason to
pursue research on emu oil." Another notable aspect of the Invention indicates
the ease by which the compositions may be formulated.
"The compositions of the
invention may be readily formulated by those skilled in the art using
appropriate vehicles to produce a variety of topical compositions including
liniments, aerosols, creams, ointments, gels, lotions and the like" reads the
patent. Perhaps the most exciting aspect of this documented research from the
perspective of the emu rancher is the unmistakable recognition by the US
government that emu oil really does contain an active component. Strickland
noted that many drug formulations are based on an active, natural source.
"Even aspirin, one of the most
widely used compounds, is based on salicylic acid which is found in the bark of
the willow tree," he explained. Edna Hennessee of the Cosmetic Specialty Labs,
Inc., notes that ingredients from natural sources provide an excellent base for
cosmetics. "In my 53 years in this business, I have found that it is very
difficult to duplicate (synthetically) what nature has provided. That emu oil is
simply good stuff," she asserts.
A brief summary of the claims
listed in the patent lay claim to:
-
A biologically active
yellow-coloured component of emu oil prepared in a prescribed manner;
-
A composition comprising the
aforementioned component and a pharmaceutically acceptable carrier;
-
The composition noted above
in an injectable form, an oral form, and a topical form;
-
method of extraction;
-
compositions with named
carriers;
-
compositions with emu oil
concentration levels of from 20 to 95%;
-
topical compositions with the
yellow-colored component comprising 1-99% by volume and method of extracting
the component;
-
named chemical treatment of
the component upon extraction;
-
methods for the prophylaxis
and treatment of musculoskeletal or dermatological conditions arising from
inflammatory reactions of environmental or a systemic origins.
The compositions named within
the patent call for a pharmaceutically acceptable carrier to transport the oil
through the skin. Despite documented, continuing investigations being conducted
by researchers on the transdermal qualities of the oil (Auburn University), the
experiments discussed within the patent indicate that best results were obtained
when the oil was combined with a separate carrier such as isopropyl alcohol,
eucalyptus oil, etc. When the mixture was applied to the skin of rats, potent
anti-inflammatory activity was observed, according to the patent.
When various pathologies go
wrong, this oil helps them to respond.
"The fact that emu oil helps
normalize basic cellular function in so many skin ailments is outstanding. Emu
oil has been successfully employed on various types of burns as well as on
abrasions and also gaping wounds."
Emu oil is just one of the
mediums currently being employed by a growing number of physicians in
alternative and conventional health care. Because so many users of emu oil often
appear to experience complete alleviation from various conditions, the question
arises: How does the oil work? The explanation according to Dr. Leigh Hopkins,
consultant pharmacist and Clinical Professor of Pharmacy, lies within what
happens with various pathologies and how the oil may help bring those back into
correct balance.
In a recent interview, Hopkins
offered to share a macro view of a plausible explanation of the discerned
benefits of emu oil in relation to various skin conditions. Hopkins emphasized
that today's modest explanation of how emu oil works may be modified as
additional research is documented.
Using Emu Oil for Carpal Tunnel Syndrome
Dr. Leigh Hopkins
Several folks have reported
relief from carpal tunnel syndrome symptoms of the burning and tingling numbness
in the fingers, with applications of emu oil to the wrist area. Since some
individuals suffer permanent nerve damage from carpal tunnel syndrome, it is
worth some degree of caution when recommending emu oil for treatment.
Carpal tunnel syndrome is a
repetitive stress injury reported at an increasing rate in the U.S. work force.
Anyone who does repetitive work with their hands and arms is susceptible.
Musicians, cooks, writers, typists and others complain of finger stiffness in
the morning, a weakened grip and pain and numbness in the hands and wrists.
The syndrome occurs when the
tendons in the wrist become inflamed after some type of aggravation such as
typing or writing. These tendons pass between the bones and ligaments of the
palm of the hand in a constricted area called a tunnel. Treatment includes
resting the hands using splints. Oral and injected anti-inflammatory drugs such
as ibuprofen are also common treatments. Surgery may be used to expand the
tunnel and reduce the pressure on the nerve that is causing the pain.
The National Institute of
Neurological Disorders and Stroke reports that 1% of individuals with this
syndrome develop permanent injury. The majority recover completely and can avoid
re-injury by changing the way they do repetitive movements, the frequency with
which they do the movements, and the amount of time they rest between periods
when they perform repetitive movements.
An uncommon but very effective
treatment is to take vitamins B6 and B2. Doctors noticed that carpal tunnel
syndrome often occurred in women on birth control pills that had high estrogen
doses (these products are no longer available). Pregnant women also have an
increased risk for carpal tunnel syndrome. And finally, diabetics are also at
increased risk. All these conditions are associated with an increased need for
vitamin B6. The dose of vitamin B6 is 200 to 300 mg per day in divided doses.
Vitamin B2 is necessary to convert vitamin B6 into its active form. This
treatment should be tried for three months; if there is no symptom relief by
then, vitamin B6 may not be for you.
In summary: Emu oil may act in
an anti-inflammatory manner to relieve the symptoms of carpal tunnel syndrome
similar to oral anti-inflammatory drugs such as aspirin and Motrin. Vitamins B6
and B2 can be taken for 3 months at a daily dose of 300 mg for each vitamin.
These should be taken in 100 mg. doses at each meal. If, after a trial of 3
months there is no benefit from the use of emu oil and the B vitamins, you
should seek other therapies since permanent nerve damage may occur in some
people.

The Mechanics of Emu Oil and Its Relation to Skin Afflictions
by Beth Silva
Emu oil is just one of a number of mediums currently being employed by
a growing number of physicians in alternative and conventional health care.
Because so many users of emu oil often appear to experience complete
alleviation from various conditions, the question arises: How does the oil
work? The explanation, according to Dr. Leigh Hopkins, consultant pharmacist
and Clinical Professor of Pharmacy, lies within what happens with various
pathologies and how the oil may help bring those back into correct balance.
In a recent interview, Hopkins offered to share a macro view of a plausible
explanation of the discerned benefits of emu oil in relation to various skin
conditions. Hopkins emphasized that today's modest explanation of how emu oil
works may be modified as additional research is documented.
Dual Delivery
Today, emu oil is being used around the world by a growing number of individuals,
from pharmaceutical and cosmetic product manufacturers to family physicians and
compounding pharmacists.
"It's clear from documented 'before and after' pictures and from what we
hear and see - sorting through real activities of the oil verses coincidental,
chance occurrences - that healing is occurring," says Hopkins. "At the
same time, when the oil is used in a topical application on normal or dry skin,
for example, there's also an improvement in the quality of the skin itself that
occurs fairly quickly. This indicates that there are two processes going on, one
of which deals with the epidermis (skin's outer layer), which is essentially
a dead layer of protein."
Hopkins explains that the epidermis serves as the protective function of the
skin and is analogous to fingernails, toenails or hair - all being nonviable cells.
"While you may be able to hydrate the skin -
plump up the epidermis and make it softer and smother - that's incidental to the
healing benefit that's also being seen with the oil," adds Hopkins. "The healing
has to be occurring within the dermis (skin's lower levels), and in the cells
that are viable, that is, cells that can divide. Those are the cells from which
healing has to come. And those cells, depending on the nature of the wound, may
have to differentiate into other types of cells. So, the healing process occurs
from the dermis and emu oil has an impact on healing at the dermal level."
Because activity is occurring at both the
epidermis and the dermis levels, Hopkins comments that there could be two
entirely different mechanisms - two explanations, and probably multiple
different explanations for the activity at either site. Putting it simply,
there's no single explanation as to the function of emu oil as it relates to the
restoration of various conditions.
Operating Across A Broad Range of Mechanisms
Numerous companies now offer pure emu oil.
This is because emu oil has been documented to exhibit anti-inflammatory,
moisturizing, and significant epidermal proliferative activity (among others),
and the oil appears to promote faster healing of burns with less pain and
scarring.
"It's that broad group of activities that
make the emu oil appear to be snake oil," says Hopkins. "If we take a series of
skin conditions that respond in various ways to emu oil, such as dry skin,
various bums, ulcers, wounds, eczema, psoriasis, etc, each of those conditions
in the hands of conventional medicine has its own unique therapeutic approach.
That the oil works where we use a number of different types of drugs is what
makes it hard for the conventional medical community to accept that the oil can
be operating across a broad range of disease conditions by way of some common
action within the dermis layer of the skin."
Hopkins relates that one problem the emu oil
industry faces is coming up with explanations as to why the oil helps alleviate
various pathologies. He remarks that the industry has to explain fundamental
mechanisms under which the oil is working.
"And those more fundamental mechanisms are
really basic nutritional mechanisms - fats that are in emu oil," says Hopkins.
"And the ratios of fats in emu oil are critical to the normalization of the
healing process. I don't want to single out a single fat, that's probably
incorrect, it's more the composition of fats in emu oil (linoleic, oleic,
palmitic, stearic, palmitoleic) or a ratio of saturated to unsaturated fats or
some other relationship within all these fats rather than a specific fat that's
in the oil. If it were such that it was a specific fat, there are a lot of ways
to get those fats from other oils. But the ratio of those fats are likely to be
important to the benefits that we see with the oil."
Examining the Healing Process On a
Cellular Level
Dr. Hopkins, whose undergraduate work was in
biochemistry, relates that there may be numerous explanations for emu oil's
specific influences on body cells themselves and on receptors within the cells.
He also mentions that emu oil does more than just prompt healing.
Says Hopkins, "It's clear that the oil does
work and this would have to be labelled in a macro and fundamental level of
healing. And we don't necessarily want to think of emu oil as stimulating
healing -it can be retarding or blocking an excess activity as well as
stimulating underperforming activity. Any and all of those depends on the
underlying explanation for a specific disease."
Hopkins says that this may be the case with
the use of emu oil with psoriasis or other skin maladies. "In certain
conditions, taking psoriasis (a condition that responds in a variable fashion to
emu oil) for example, in which there are specific cells that are out of control
- those cells need to be tamed, if you will."
According to Hopkins, a better way to
describe what emu oil does for the body would be that "...emu oil helps to
normalize basic cellular function, and enable the body to progress with what
should be normal healing."
"We know from our experiences that the oil
does work and it does normalize various conditions," continues Hopkins. "And I
emphasize normalization. With emu oil we can typically increase or decrease
whatever is going on because often the problem is because something Is either
not performing well enough, or another system is overperforming. For example, an
excessive inflammatory condition is an overperformance of a system that's
designed normally to produce an inflammatory response because that's part of the
body's normal response to some invasion of organisms or other foreign
substances. The concept of normalization involves progressing past that
inflammatory phase and moving into the next phase of the response - to whatever
has been presented to the body. And sometimes things get hung up in those
different phases and you have to give them a little boost - get them moving."
Hopkins relates that at the root of almost
every chronic and acute skin condition is a cell line or a hormonal response
that is exaggerated, which needs to be kicked into its next phase of healing. He
adds that these are complex phases of healing that go on and are incompletely
understood.
The fact that emu oil appears to help
normalize basic cellular function in so many skin ailments is outstanding. Emu
oil has been successfully employed on various types of burns as well as on
abrasions and also gaping wounds.
Regarding the use of emu oil on deep wounds
Hopkins says, "It's very impressive when you see after a certain amount of time
that you can have an essentially completely healed system - everything has been
replaced, the muscle, the tendon, the nerves, the blood vessels, the skin -
repaired and grown back. The very impressive ability of the oil is that it seems
to encourage those systems to work in concert as they're designed to do. When
you're deficient in certain components, that system then doesn't heal normally,
quickly, etc. and the oil simply helps to orchestrate the healing process."
