Pueraria mirifica, also known as กวาวเครือ Kwao Krua (but not exclusively), is a plant found in northern and north eastern Thailand and Myanmar.
In Thailand, the plant is known as “Kwao Krua” and has a history of use in folk medicine.[citation needed] Although the name “Kwao Krua” had been applied to several species of plants having tuberous roots, it was definitively identified as Pueraria mirifica in 1952. An unusual estrogenic phenol, miroestrol, was isolated eight years later from this plant.[1]
