Key ingredients of breast enlargement pills are phytoestogens, a non-hormonal plant estrogen, which supports the growth of new breast tissues. Cosmetic companies that produce such pills explain that they stimulate estrogen production in the breasts and thus they help for breast enlargement.

Usually pills are made of seven ingredients, among which are fenugreek, don quai, saw palmetto, wild yam, blessed thistle, and damiana. This herbal combination adjusts the hormone levels and help for the growth of the breasts. According to cosmetic companies, one can have visible results after just a couple of weeks. The companies also claim that continuous intake of pills for a period of 3-6 months will result in increase by 1 or 2 sizes.

Some studies, however, claim that these pills are not only inefficient, but that they are even dangerous. Actually, no researches on the way they work have been published in the medical journals, thought cosmetic companies assert so.

Numerous researches prove that the ingredients of the breast enhancement pills interfere with some medicines. For example, fenugreek interferes with blood clotting medicines, and the chaste-tree interferes with bird-control medicines. One of the ingredients, don quai, is known to be carcinogenic.

Breast enlargement pills are sold as herbal supplements and Food and Drug Administrations do not monitor and control their quality, safety and efficiency. It is recommended that one finds more information about the herbs and ingredients used in the pills, before they start taking them. It is also important to get familiar with the possible side effects and undesired complication that can result from the consummation of the pills.
