Overview
Wild yam
(dioscorea) is a plant that is indigenous to the Americas, with
many varieties growing from New England through Mexico and South
America. It’s been used for centuries to relieve menstrual
cramps, colic and other types of abdominal cramps.
Scientists have discovered a substance in the dried root,
diosgenin, can be used to synthesize progesterone under
laboratory conditions. This has led many to believe that wild
yam root and wild yam extract might be a substitute for hormone
replacement therapy in menopausal women. There is no evidence to
support that belief, nor is there anything to suggest that the
body can synthesize progesterone from wild yam root. There are
some manufacturers, however, who add progesterone to their wild
yam formulations, and it may be that wild yam helps boost the
effects of other ingredients in the formula.
Because
of the controversy, many have discounted the very real benefits
of wild yam. As is the case with many other traditional and
herbal cures, scientists studying the effects of wild yam are
finding evidence to support the traditional uses. In at least
one case, researchers looking for one thing made the surprising
– to them – discovery that dioscorea has an antioxidant effect
that helps increase levels of HDL. Another study found that wild
yam’s anti-inflammatory effect is useful in reducing the
severity of symptoms associated with fibromyalgia.
Wild yam
is still widely used by pharmaceutical companies to synthesize
hormones, and for other uses. If you’re considering using wild
yam as a supplement or to relieve symptoms of PMS, menopause,
gastric upset or one of its many other uses, please carefully
consider the information below.
What
Wild Yam Does:
Wild yam
contains alkaloids, diosgenin and several other saponins,
glucosides found in some plants. Many saponins are currently
being studied for their antioxidant effects and their potential
to protect against cancerous changes to cells. It also acts as
an anti-spasmodic and anti-inflammatory agent, which may account
for the pain-relieving effects in treatment of abdominal and
gastro-intestinal cramping.
The British Herbal
Pharmacopoeia lists the following uses for wild yam root: mild
diaphoretic, anti-spasmodic, anti-inflammatory, anti-rheumatic
and cholagogue.
Health
Benefits of Wild Yam:
Reduces
symptoms of PMS and dysmenorrhea
Because
of its anti-spasmodic and anti-inflammatory effects, wild yam
has a long traditional history of use in treating menstrual
cramps and related complaints. It’s also long been recommended
to help reduce morning sickness during pregnancy
Relieves
colic
Wild yam
was so often used for relieving colic and intestinal discomfort
that it is often called colicroot. The root contains a chemical
substance which stimulates the production of bile, and helps to
ease the cramping and pain associated with colic. For the same
reasons, it is being studied as a treatment for ulcerative
colitis.
Reduces
pain and inflammation
Applied
as a topical cream, wild yam is readily absorbed by the skin.
The analgesic and anti-inflammatory properties are well
documented.
Possible
Side Effects of Wild Yam
Wild yam
shows few side effects in studies. Some report stomach
discomfort or rash in those who are allergic to wild yam. If you
are taking birth control pills or hormone replacement therapy,
you should consult your doctor or health professional, as there
may be some hormonal effect. This is particularly important, as
there are reports of some manufacturers adding hormones to their
wild yam creams. There is a possibility that wild yam may lower
blood sugar. Therefore if you are taking insulin or being
treated for low blood sugar, you should also consult your doctor
for monitoring if you are taking wild yam.
Summary
Wild yam
has a long history of traditional use in treating ‘female
problems’, including painful menstrual cramps, swelling and
bloating. It has been used to treat pain and swelling, and to
combat rheumatoid arthritis. The preliminary research into most
of wild yam’s medicinal research is promising, particularly in
regards to pain relief and relief of gastro-intestinal symptoms.
While
it’s been established that diosgenin cannot be used in the body
to manufacture progesterone, the jury is still out on whether
wild yam has some effect on hormone production. It has also been
studied in connection with glucose regulation and production,
and again, the preliminary research points to a possible use in
treating diabetes.
As the
possible side effects are minimal, and the possible benefits are
great (as any woman who has ever suffered from painful menstrual
cramps will tell you), wild yam cream may be helpful in
alleviating pain, muscle cramping, nausea and nerve pain.
Because wild yam is not considered a drug, however, and
therefore is not subject to strict oversight during manufacture
and distribution, we highly advise buying products containing
wild yam from a trusted source.
