Results: The results of the study showed that 19.6% of the women consumed herbs during pregnancy. The most commonly used herbs included mint, flixweld, and cinnamon; in addition, the most prevalent indications resulted from these herbs consumption were gastrointestinal complications and cold. The rate of herbal consumption in pregnancy was related to education (P = 0.001) and resistance (P = 0.008); however, no relation was found regarding age (P = 0.203), employment (P = 0.255), or gravity (P = 0.935).

Conclusions: Although the findings of this study were preferable to those of some other studies, due to the importance of the issue, it is vital that health care providers to be open to question the herbal use during pregnancy.
