Q What can you tell me about natural hormonal and herbal preparations advertised to enlarge breasts? Do they work, and are they safe? A Dietary supplements for enhancing breast size are often marketed with compelling testimonials and results from so-called scientific studies. But no clinical trial data have been published on any of these products, so we have no proof that they work.
Many supplements are marketed as natural means of breast enlargement. Breast enhancement supplements typically contain a variety of herbs, such as saw palmetto and wild yam. Supplement manufacturers often discuss the potential benefits of plant-derived substances known as phytoestrogens on breast health. However, it's not clear that phytoestrogens enhance breast growth. Serious drug interactions are possible with many supplements, especially if you take a blood-thinning medication such as warfarin Coumadin, Jantoven.
