Pueraria mirifica has a high concentration of phytoestrogens. Phytoestrogens are not hormones, but they do provide the same benefits of estrogen, which is the body's primary source for breast enhancement. Phytoestrogens maximize blood flow and estrogen distribution throughout the breast tissue, encouraging growth and maintenance of the breast tissue, firmness, and shape.

Pueraria mirifica can lengthen the milk ducts, stimulate and expand fat tissues,resulting in firmer breasts. Pueraria mirifica also maintains collagen, and develops new skin cells resulting in soft, smooth, and beautiful breasts.

Ducts branch out from the nipple to the interior of the breast, ending in clusters of the lobules. Pueraria mirifica stimulates the lengthening and ranching out of these ducts and the development of the mammary tissues.

Pueraria mirifica also increases the fatty tissue and ligaments around the breast that provide support and shape. This results in enhanced cup size. Moreover pueraria mirifica helps maintain collagen which results in giving breasts a soft, smooth, natural shape
