While anecdotal evidence suggests that chamomile tea is a natural labor inducer, there is actually no scientific evidence to support this claim. However, it is important to seek the advice of your obstetrician before consuming chamomile tea during pregnancy, as it is linked to miscarriage.
According to Dr. Pamela Pappas, M.D., the chamomile herb can stimulate the smooth uterine muscle. This can create the symptoms of labor and may, in fact, cause miscarriage in early pregnancy. This link to miscarriage may have given rise to the claim that it induces labor. Many medical experts recommend avoiding chamomile tea during pregnancy.
