Breast development begins at puberty and is regulated by the balance of specific hormones. Medical research has shown that the development of breast tissue depends on the delicate balance of progesterone, estrogen, prostaglandins, prolactin and other compounds. An imbalance of these hormones can result in poor breast development or even atrophy (decrease in size).

Phytoestrogens are a group of substances found in plants that have moderate estrogenic properties. The phytoestrogens compete for the same receptor cells as true estrogen. Asian women that have diets rich in plants that contain phytoestrogens have been found to have a lower incidence of breast cancer. Recent research concerning phytoestrogens suggests that they have an important role in reducing breast cancer, heart disease, and the symptoms of menopause.

Phytoestrogens, through their natural balance of female hormones, promote the development of glandular breast tissue. Most women taking herbs containing these phytoestrogens notice a significant increase in the fullness and balance of their breasts.

Saw Palmetto contains some of the highest concentrations of phytoestrogens recommended by herbalists for breast enlargement. Saw Palmetto is a low growing palm whose berries have been cherished by herbalists and natural medicine practitioners for years. Saw Palmetto, sometimes known as sawtooth palm or windmill palm, grows in the southeastern United States from South Carolina to Southern Mississippi and also grows naturally in every county of Florida.

The hard saw teeth for which the plant is named run along the petiole, or leaf stalk. Saw Palmetto is a remarkable herb for both men and women. It is now a popular and effective treatment for prostate enlargement in men but has it's origins in natural medicine as a breast enlarger and is still recommended today by naturopathic physicians for increasing breast size. Saw Palmetto has been used for centuries in different cultures. Native Americans, dating back to pre-Mayan civilizations, used the plant for food and medicine and particularly for breast disorders in women. Saw Palmetto is useful as a nutritive tonic, supporting the function of a healthy appetite and smooth digestion. It also tones the urethra, and it may be used to uphold the healthy function of the thyroid gland and urinary system. This herb has no side effects or drug interactions.

There are a number of other herbs that are also effective in combination in reactivating breast tissue growth.

Fenugreek is a unique herb rich in phyto-estrogens. Fenugreek aids in hormonal production, and facilitates the development of the mammary glands which feed on estrogens. Fennel has long been praised for its abundance of flavonoids. These compounds exert mild estrogenic effects and are completely harmless and non-toxic. Damiana is a small shrub high in phytochemicals such as alpha-pinene, beta-carotene, beta-pinene and beta-sisterol. Damiana is primarily used for treating female hormone imbalances.
