Herbal supplements claiming, without evidence, to enlarge breasts
Breast enlargement supplements are frequently portrayed as being a natural means to increase breast size, and with the suggestion that they are free from risk.[1]: 1330 The popularity of breast enlargement supplements stems from their heavy promotion[1]: 1330 toward women.[2]: 1345 Though there has been historical folklore about using herbs for breast enlargement,[2][3] there is no scientific evidence to support the effectiveness of any breast enlargement supplement.[1][2] At times, testimonials by companies have been faked.[2]: 1345
Products typically contain a variety of ingredients of plant or fungal origin. The compounds claimed to be pharmacologically active are typically estrogen mimics (called xenoestrogens; specifically known as phytoestrogens in plants and mycoestrogens in fungi).[9]
Commonly used ingredients include:[1]: 1330 [2]: 1345
There is inadequate scientific study whether herbal breast enlargement can be safely achieved.[2] It is unlikely that any of the common ingredients would be efficacious.[2]: 1347 [8] No randomized, blinded and fully controlled tests has been performed to test any breast enhancement product.[1]: 1332 Most supplement ingredients do not have significant adverse effects, but some ingredients are potentially dangerous for consumption or use.[2]: 1348
Black cohosh has been shown to have no estrogenic effect in vivo or in vitro.[1]: 1330
Hops contains estrogen-like compounds, called prenylflavonoids, the most potent of which is 8-prenylnaringenin.[11] Hops' effect on fertility lacks research.[10]: 4914 Prenylflavonoids from hops have anticancer properties.[11]
Zearalenone and its derivatives are a class of xenoestrogens associated with many herbal bust enhancement products.[9] There have been some claims that zearalenone can increase the size of breasts in humans, but there are no tests of efficacy or safety.[2]: 1345 Zearalenone, produced by a toxic fungus, is a mycoestrogen that stimulates the growth of breast cancer cells, increases the chance of estrogen dependent breast cancer, and may reduce fertility.[9] Other supplements are unlikely to have been spoiled with the mould.[2]: 1348 [10]
Indirect assay tests of the product Erdic (also known as Bust out) on the uterus of rodents, by measuring the amount of estrogen present, showed no difference from the control.[2]: 1345 Preliminary findings in 2001, in mice, suggested that hops-based products would be ineffective.[12] Another test, of a hops ingredient on mice showed weak effects for high dosages.[2]: 1346 [10]Diosgenin, which is present in fenugreek and wild yam, affected maturation, but that wasn't enough evidence for this indication.[2]: 1347
Some medications have been involved in breast enlargement as a side effect.[2][8]
