Is Wild Yam Okay to Take While Pregnant?

No studies address safety during pregnancy of wild yam, a phytoestrogen also known as rheumatism root or sold as natural dehydroepiandrosterone (DHEA). According to the National Institutes for Health, there are also no studies assessing potential toxicity to an expectant mother or her fetus.

Fact

• During the 1960s, hormones were chemically manufactured from Mexican wild yam. Based on this, people assume that wild yam contains hormones. But according to the National Institutes for Health, wild yam contains no hormones or hormone precursors, like progesterone.

Rumor

• Rumor holds that wild yam contains progesterone and its use supports pregnancy and eases morning sickness. This benefit is more closely associated with capsule forms of wild yam.

Considerations

• It is possible that a nonhormonal substance in wild yam stimulates uterine contractions. While this may be helpful during labor and delivery, it is dangerous in the months before labor and delivery.

Theories and Speculation

• The body does not convert the active ingredient in wild yam, diosgenin, into hormones. Some wild yam products may be laced with artificial hormones, which may prove harmful during pregnancy.

Warning

• You should never assume that nonprescription, natural or organic products are safe. Err on the side of caution while pregnant. Any substance that may alter your hormone levels may change your pregnancy and its outcome. Consult a qualified physician before using such products.
