Why is neem bark or oil taken by mouth during pregnancy considered likely unsafe?

Answer

Potential to induce a miscarriage due to properties studied for contraceptive effects

Ingestion of neem oil or bark during pregnancy carries significant risk because the components of neem have demonstrated biological activity that impacts reproductive function. Specifically, certain constituents within neem have been the subject of study due to their potential contraceptive effects. When consumed orally by a pregnant woman, this biological property translates into a serious hazard: the high likelihood of inducing premature labor or miscarriage. Because of this direct threat to the viability of the pregnancy, internal use is strongly advised against during this sensitive period.
