Most women are very concerned about aging, particularly concerning the effects brought about by the aging process. For the average women, menstruation cycles end at 48-50 years of age when the reproductive system stops or slows down functioning. The body experiences dramatic changes due to lower estrogen levels: the body's systems and its functions begin to decelerate and the immune system weakens accordingly. Menopausal women will usually experience both psychological and physiological changes. Psychological changes range from anxiety, tension and nervousness to chronic depression, whereas the physiological changes include hot flushes, fatigue and insomnia to more severe conditions as bone loss, balding and degeneration of the reproductive area.
Consequently, women at the age of 45-50 and post-menopausal women need something to replace the loss of natural estrogen. Hormone replacement therapy (HRT) has been extensively used to alleviate both the psychological and physiological changes. However, this estrogen substitute can be quite expensive and must be conducted under a physician's close supervision. An effective alternative approach would be to delay those aging problems by using natural phytoestrogens present in Pueraria mirifica as a dietary supplement.
Local communities in Thailand have used Pueraria mirifica (White Kwao krua) for well over a hundred years, specifically for its rejuvenating qualities. The belief in the rejuvenating properties of Pueraria mirifica has been passed down from one generation to another and more recently through the publication by Luang Anusan Suntara.
In May 1931, Luang Anusan Suntara published a pamphlet on the subject of "Kwao Krua" describing different ways of preparing traditional folk medicine using Pueraria mirifica and the claims of its rejuvenating power. It is stated in the pamphlet that Pueraria mirifica can:
Serve as an anti-wrinkle agent for aged and wrinkled skin
Darken white hair, and increase hair growth
Alleviate cataract problems
Help with memory loss
Increase energy and vigor, increase flexibility in bodily movements
Increase blood circulation
Increase appetite, and
Alleviate sleep disorders
In 1932, Dr. A.F.G. Kerr, the Director of the Botanical Section of the Journal of the Siam Society, directed the attention of the scientific community to the fact that the tuberous roots of a Thai plant called "Kwao Krua", mistakenly identified then as Butea superba, were considered to be of value as a rejuvenating drug.
Dr. Kerr was the first to create international awareness of the rejuvenating qualities of this plant, which subsequently led to the isolation of a potent phyto-estrogen that is unique to this plant only and to the identification of the plant as Pueraria mirifica in 1952.
Serves as the "Fountain of Youth" for aged men and women.
