About Our St. Herb Store

Pueraria mirifica, widely known as Kwao Krua, is a rare herbal plant indigenous to the deep forests of northern Thailand. For generations, it has been treasured in Thai traditional medicine for its remarkable health and rejuvenating properties. Revered as a national symbol of herbal wisdom, Kwao Krua continues to play a significant role in modern herbal studies and wellness innovations.

Its powerful natural compounds, particularly phytoestrogens, have attracted interest from researchers and health experts worldwide. Unlike synthetic hormones, these plant-based estrogens are known to help enhance skin firmness and support natural breast fullness by increasing cellular turgidity—without affecting cell growth or causing hormonal imbalance.

Today, Pueraria mirifica is not only a cornerstone of traditional Thai remedies but also a key ingredient in modern natural wellness solutions. Several leading universities in Thailand have recognized its importance by incorporating Kwao Krua into postgraduate herbal medicine programs, bridging the gap between ancient knowledge and scientific research.
