Native to the Indian
subcontinent, Gymnema has been used for over 2000
years as a diabetes remedy. Classical descriptions indicate
gymnema for treatment of "honey
urine" (the tasting of urine was
common practice by
doctors of the past in order to
diagnose diabetic conditions). When
the leaves of the plant are chewed,
they interfere with the ability to
taste sweetness; thereby it became
known as gurmar, or ‘sugar
destroyer' in India. Because of this
quality, gymnema has
been marketed as an appetite
suppressant and to promote weight
loss. However, there is no evidence
that gymnema has these effects. Taking capsules of gymnema will not
alter one's taste perception of
sweetness; the leaves must be chewed
directly in order to experience this
sensation.
Parts Used
The applicable parts
of this plant are its leaves. As
mentioned, directly chewing on the
leaves will temporarily block the
ability to taste sweetness. This however,
is not the typical administration
for gymnema to exert its medicinal effects. Although this
herb is used for conditions
involving irregular metabolism of
sugar, it is interesting that the
sweet blocking ‘side effect' of this
herb occurs.
Gymnema Uses
Gymnema has been used
historically to treat diabetes, coughs, as a laxative, digestive
stimulant, and as a snakebite
antidote. Modern research has
focused on the abilty of
gymnema's effects in diabetic
conditions and thus remains the main
application of this plant medicine
today.
Gymnema is appropriate as an
adjunctive diabetic treatment in
several aspects, appearing to work
via a combination of mechanisms. Primary research has shown that gymnema
is able to increase the
number of insulin-producing cells in
the pancreas of laboratory animals,
reestablishing normal blood sugar
concentrations. [1] Gymnema
can increase the metabolic
activation of the enzymes that drive
glucose absorption and utilization
in the cells, thereby increasing the
efficiency by which the body can use
its primary fuel source.[2]
Gymnema can also slow
the use of glucose peripherally by
other hormones in the body (somatotrophin
and corticotrophin); this allows the
serum levels of glucose to remain
more stable in those with a
propensity toward irregularities in
blood sugar. [3]
Taking gymnema may also slow the
absorption of glucose, or sugar,
from the intestine, thereby slowing
the demand on the body for insulin
production. [4]
All of these effects make gymnema an effective diabetes adjunctive
treatment.
Two constituents of gymnema leaves, gymnemic
acid and gurmrin, are
thought to be responsible for
blocking the taste of sweetness;
gymnema does not prevent the tasting
of sour or astringent flavors. [5]
Varying doses have
been suggested pertaining to recent
research findings; however 400 to
600 milligrams per day is the most
common dosage. [6,
7]
These studies do not
describe frequency of dosage
throughout the day; however due to
the fact that this herb is taken to
control blood sugar, divided doses
throughout the day are recommended.

Gymnema Toxicities and
Contraindications |
Gymnema Side
Effects:
No side effects have
been
reported when using this herb,
except for the expected decrease in
blood sugar levels. The safety of gymnema has not been established in
pregnancy and should therefore be
avoided.
General
interactions:
No interactions with
other supplements, herbs, or foods have been reported when using gymnema. Taking gymnema prior to
testing for blood glucose may cause
fictitiously lower levels of this
test.
Drug
interactions:
Gymnema assists the
body in lowering elevated blood
sugar levels. Therefore, if one is
diabetic and using any diabetes
medications, including insulin, one
should use caution if combing this
herb with these medications.
Disease
conditions:
Gymnema may lower
blood sugar in diabetics; blood
glucose should be closely monitored
especially when administered with
antidiabetes
medications.
