Herbs and Supplements to Avoid
The term “amenorrhea” literally means an absence of menstrual bleeding. In medicine, it is used to indicate one of two conditions: the cessation of menstrual cycle in a woman of menstrual age or the failure to develop a menstrual cycle at all in a young woman who has reached the age of 16 years old. This article only addresses the first of these conditions, technically called “secondary amenorrhea.” To avoid using this long term, we will simply refer to the condition here as “amenorrhea.”
There are many causes of amenorrhea. Severe weight loss, such as may occur in a woman with anorexia nervosa, can cause the menstrual period to stop. So can extreme exercise, such as marathon running, bodybuilding, or professional-caliber ballet dancing.
Young women who go to college may develop amenorrhea too, possibly from stress or perhaps as a reflex reaction to what the body considers a “migration.” Pregnancy and nursing stop the menstrual cycle by design. Finally, women who have used oral contraceptives may find that it takes a while for a normal menstrual cycle to return after discontinuing them.
More rarely, amenorrhea may indicate a serious medical condition, such as a disorder of the pituitary gland, the hypothalamus, or the ovaries. For this reason, it’s a good idea to check with your doctor if you miss more than one menstrual period, to see if more evaluation is needed. Medical treatment for amenorrhea depends on the cause. If examination reveals no underlying cause, physicians may recommend a period of oral contraceptive use to start up the cycle.
The hormone progesterone, available (probably inappropriately) as an ingredient in some “natural” creams, may help restore the menstrual cycle. In one double-blind, placebo-controlled trial, oral use of a micronized form of progesterone restored a normal menstrual cycle in women with secondary amenorrhea.1 However, although progesterone is marketed as a “natural hormone,” it is as much a drug as estrogen, and should never be used without medical supervision.
In some women, the pituitary gland produces excess levels of prolactin. Prolactin is a hormone that naturally rises during pregnancy to stimulate milk production; it can also cause amenorrhea. Excessive pituitary prolactin release is a condition that must be investigated medically because it may indicate the presence of a tumor. However, it is possible that slight abnormalities in prolactin level without a dangerous medical cause may trigger amenorrhea in some women. The herb chasteberryis thought to reduce prolactin levels,2–4and for this reason it has been tried for amenorrhea.5 However, as yet no double-blind, placebo-controlled trials on this potential use of chasteberry have been reported. The herb bugleweedis also thought to reduce prolactin levels,6 but it too has not been tested for amenorrhea.
Other commonly proposed natural treatments for amenorrhea include the supplements vitamin B6 and zinc and the herbs blue cohosh, angelica, asafetida, alfalfa seed, motherwort, parsley, and rue. However, there is no meaningful scientific evidence to indicate whether they are effective.
For reasons that are not entirely clear, women with amenorrhea often have an accelerated rate of bone loss, potentially leading to osteoporosis. Women who have developed amenorrhea due to heavy exercise tend to experience an accelerated rate of bone loss, which may lead to osteoporosis. Unfortunately, calcium and vitamin Dsupplements are not sufficient to protect bone mass under these circumstances.7 Stronger measures, such as reducing exercise or using medications, may be necessary.
