St.herb puerariamirifica cream enhances and stimulates estrogen-sensitive breast tissue and helps enhance breast size naturally by introducing phyto-estrogen (naturally occurring plant estrogen) from pueraria mirifica directly into the estrogen receptor sites.

This stimulates the development of mammary tissues to give you a fuller and firmer bust-line. Most women will see this dramatic change in 3-6 months. Once you have the bust size you always wanted, simply continue for another 3 months maintenance period. The results are natural, completely safe, long lasting and in most cases permanent.




Pueraria mirifica is Thailand’s endemic species found mainly in the northern and western part of Thailand and has local name as “White Kwao Krua”.

Pueraria mirifica accumulate “phytoestrogens” comprising isoflavone. The compounds that make Pueraria mirifica different from any other phytoestrogen- containing plants in the Family Leguminosae are Miroestrol and Deoxymiroestrol, which possess highest estrogenic activity among the known phytoestrogens due to structural similarity to estradiol. The chemical structures of the two compounds are very similar to that of estradiol, the main human estrogen.

What Makes Pueraria Mirifica - The Best Phytoestrogen?

"Miroestrol and Deoxymiroestrol" is very different from other phytoestrogen, as it posses highest estrogenic activity among the known phyto-estrogens due to structural similarity to estradiol,
(Estradiol is the main human estrogen which can be found in all women who are at the stage of
nursing baby); as you may notice that all women who are in this stage, their breast will enlarge and gain firmness for feeding purpose. Pueraria Mirifica posses highest estrogenic activity among the known phyto-estrogens due to structural similarity to Estradiol!

In 1940, in a protected biotechnology laboratory, a group of German scientist successfully isolated the phytoestrogen – Miroestrol from the root of Pueraria Mirifica. But, this herb is mistakenly reported then as Butea Superba. It was later on classified as a new plant called Pueraria Mirifica. After another 60 years, in year 2000, another phytoestrogen – deoxymiroestrol is isolated from the root of Pueraria Mirifica.
