Ephedrine |
|
Much
has been written and spoken about Ephedrine, and some concerns
have been raised regarding its use as a dietary supplement.
Unfortunately, as Dr. Zoltan P. Rona, a practicing medical doctor
in Toronto, Canada, has noted, "much of the information being
released on Ma Huang is misleading."
While TSN Labs, Inc. sees it as a positive sign that people
are taking an interest in the safety of the supplements they
use, we feel it is extremely important that these people have
available to them accurate and credible information upon which
to base their judgements. For this reason, the following information
is provided with the intent of educating supplement users as
to the background and current situation surrounding the use
of one of nature's oldest medicines. Simply put --- Don't believe
the hype..... Educate yourself!!!!

Effective natural weight loss Ma Huang products available, check

History
Ephedrine
is known as one of the world's oldest medicines. Ephedrine
is a member of the family of herbs known as the Ephedraceae.
It has been used in China for more than 5,000 years to treat
symptoms of asthma and upper respiratory infections. Related
varieties of the herb are also grown in India, Europe, Australia,
and Afghanistan. American ephedra, native to the dry southwest,
was used as a tea by the area's native people and introduced
to early American settlers, who called it "Mormon Tea."
It has also been used in the treatment of headaches, fevers,
colds, and hay fever. Today, compounds derived from this
herb are commonly found in many over-the-counter (OTC) cold
and allergy medications. Ma Huang is also found in some
weight loss and energy products. For dieters, it suppresses
the appetite and stimulates metabolism through a process
known as thermogenesis. Recently, Ma Huang has been the
subject of scientific research for obesity because of this
thermogenic fat-burning effect.

| "A recent
study found that in the most overweight individuals,
the combination of ephedrine + caffeine(EC) was
29% more effective than dexfenfluramine. Another
study found that when compared to losing weight
by diet alone, EC had a positive influence on body
composition, increasing fat loss by 100% and decreasing
muscle loss by 72%." Townsend
Letter for Doctors & Patients - June 1996 |
During the Food Advisory
Committee's recent hearings in Washington, D.C.,
the FDA attempted to discourage speakers and members
of the committee from discussing the benefits of
ephedra as an agent to aid in weight loss. |
| "None of the literature
reports support the contention that ephedrine in
reasonable dosage would represent a hazard to health...
In the formal study, 100 subjects received...Ma
Huang at an average dose of 5 tablets [23 mg/tablet]
per day for 8 weeks. No side effects of any kind
were reported, no changes in blood pressure were
seen, rates of weight loss improved..." Safety
of Ephedra Herb: A Preliminary Report. |
The FDA's allegations
of risk are not supported by scientific or empirical
data. The FDA has not cited a single article to
support its conclusions, nor has it made any attempt
to rebut the studies and over 200 articles from
scientific literature supporting the safety of ephedra
herb which have been submitted.. |
| Scientifically
Recognized Dosage |
|
| "There
have been more than 20 significant publications
in prestigious scientific journals, describing the
effects of ephedrine in doses of 60-150 mg per day
for periods of up to 26 months... Ephedrine...did
not cause increases in blood pressure or heart rate...There
were no clinically important side effects in the
reviewed studies..." Ad Hoc Committee On the
Safety of Ma Huang - June 1995. |
FDA is considering a
serving limitation of 2-10 mg without having any
studies suggesting that larger servings are unsafe
and contrary to its own OTC Regulations. |
| "25 mg up to six times
per day." FDA's Over-The-Counter Drug Regulations. |
|
| Safety
Factor |
|
| "The drug ephedrine...poses
little risk when compared to common household products
such as aspirin, ibuprofen, acetaminophen, sleep
aids and caffeine." Ad Hoc
Committee On the Safety of Ma Huang- September 1996. |
There are only about
36 reports available to the FDA in which it can
even be determined what amount of ephedra was claimed
to have been consumed by the reporting individual. |
| The Committee on Safety
of Medicine in the United Kingdom recently acknowledged
that it had only received 22 reports of adverse
reactions associated with ephedrine drug weight
loss products over a multi-year period. Recent Danish
data on an ephedrine-caffeine combination for weight
loss indicated only 86 reportable adverse reactions
over a two-year period from 9.6 million reported
25 mg servings. |
Even the FDA concedes
that most cases are complex, with patient factors
that make interpretation of individual events problematic.
Moreover, these reports come from a population of
at least 8 million Americans who consume over 1
billion servings of ephedra herb products each year. |
| "A retrospective study
of 230,000 subjects, who over a three-year period
had used ephedra herb supplements at single servings
of about 20 mg/3-5 times per day, for periods of
six to eleven weeks, revealed no serious adverse
effects, including no increases in blood pressure
and no increases in heart rates." Ad
Hoc Comm. on the Safety of Ma Huang- Sept. 1996 |
FDA has received only
602 unverified and unevaluated reports,
many of which have been subsequently proven to be
erroneous, unrelated or involve consumption at extreme
levels. |
| Alleged
Injuries |
|
| "The scientific
literature reviews, clinical testing, animal studies,
known toxicology, absence of injuries in over-seas
or other defined populations, and the safe use of
ephedra herb products at 25 mg doses without adverse
incidents all demonstrate that ephedra herb dietary
supplements are unlikely to pose a risk of injury
at labeled servings, a fact confirmed by thousands
of years of use. Given this scientific background,
any reported injuries should be scrutinized with
great care, because such reports are at odds with
all that is known about these products' safety."Ad
Hoc Comm.on the Safety of Ma Huang -Sept. 1996. |
The FDA treats all alleged
complaints as valid, regardless of whether an actual
injury occurred. For instance:
-Several reports failed to state
an injury
-Dozens of cases were included where
the patient was taking multiple prescription drugs
with known side effects and such side effects
were erroneously attributed to ephedra
|
| Internationally respected
toxicologists reviewed the reports collected by
the FDA and the Texas Dept. of Health. Their response
was that "it is impossible to establish any causal
relationship between ingestion of these products
and any serious adverse effect...It is our opinion
that at the labeled doses...there is virtually no
basis, in these materials or the literature, to
conclude [that these products] would cause any serious
adverse effect in human beings." Ad
Hoc Comm. on the Safety of Ma Huang -Sept '96 |
-Several reports came
from unidentified "friends" who alleged bad experiences
without any detail
-Several claims counted by the FDA
concerned products containing no ephedrine. Even
more alarming is that the FDA was advised of this
fact in 1995 yet continued to include them.

Drugs
vs. Nature
While
the above table demonstrates the safety of ephedrine, it
should be noted that many scientists and herbalists argue
that use of the herb in whole plant form is even safer than
the refined derivative (pure ephedrine & psuedoephedrine).
In fact, studies show that the whole herb Ma Huang has a
very low toxicity and little potential for side effects
(Tang & Eisenbrand, 1992), and animal studies have failed
to demonstrate carcinogenic or mutagenic potential for ephedrine.
Further, ephedrine is rapidly eliminated from the human
body -- 88% of an oral dose is excreted in the urine within
24 hours, 97% after 48 hours (Hobbs, 1996). In Herbal
Medicine for Everyone, British herbalist Michael McIntyre
writes that while pure ephedrine may raise blood pressure,
the "whole (ephedra) plant actually reduces blood pressure."
German medical herbalist Rudolph Fritz Weiss, M.D., maintains
that the whole plant "has certain advantages (over psuedoephedrine).
Above all, it is better tolerated, causing fewer...symptoms."
Finally, practitioners of Traditional Chinese Medicine (TCM)
would regularly prescribe Ephedrine with other tonic herbs
to improve safe consumption. This theory is maintained by
TSN Labs, Inc. Our product, Thin
& Slim Naturally,
was formulated by Mr. Steve Lee, a native of Taiwan. He
is a graduate of Duquesne University of Pharmacy in Pennsylvania,
with a Masters Degree in Industrial Pharmaceutics. Steve
Lee's professional experience in pharmaceutical chemistry
has been extensive and diverse, including Laboratory Manager
at the U.S. National Institute of Health. He has been instrumental
in the formulation of a wide variety of health and nutritional
products for as many as eight different companies. Mr. Lee
has served on the FDA Advisory Committee for Herbal Medicines.
Steve Lee brings to TSN Labs, Inc., a thorough understanding
of pharmaceuticals and western medical practices, as well
as a deep background in herbal medicines, whose safety and
effectiveness have been proven in China and the rest of
Asia for more than 5000 years. It is through this diverse
knowledge of both the Oriental and Occidental worlds, that
Mr. Lee has been able to formulate one of the safest and
most effective natural dietary supplements on the market
today. That product is Thin
& Slim Naturally.
