Women looking to increase their bust size with herbal supplements should think twice, according to a report published in Obstetrics & Gynecology (June 2003). "There is no scientific evidence that these products work," said Adriane Fugh-Berman, MD, author of the report. In her review, Fugh-Berman looked at scientific literature about the ingredients often found in "bust-enhancing" dietary supplements, including black cohosh, dong quai, and kava. "No clinical trial of a bust-enhancing herbal product has been published," Dr. Fugh-Berman said.
Furthermore, she stressed the fact that there are no long-term safety data on any of these herbs, either alone or in combination. Dr. Fugh-Berman recommends that physicians discourage women from using pharmacologically active substances with unknown safety risks to enlarge their breasts. She believes that there may be long-term issues (eg, an increased risk of breast cancer) in using some of these herbal ingredients because they may mimic estrogen.
