About

Red Kwao Krueng root powder, a Thai traditional botanical containing flavonoids with potential phytoestrogenic activity and limited toxicological data.

Butea superba is a Thai medicinal plant used traditionally as a rejuvenation tonic and for purported aphrodisiac effects. It contains flavonoids, butein, and steroids. The phytoestrogenic potential of butein and related compounds is noted in the literature. The plant is not listed in EU cosmetic restriction annexes, but its use in cosmetics is limited outside Thailand, meaning the Western safety database is sparse. Precautionary use at low concentrations is advisable, particularly in products intended for long-term leave-on application.

  • Bistein and flavonoids have antioxidant activity

Known concerns
