One study in rats suggested that bakuchiol and ethanol extracts of the Chinese medicinal plant Psoralea corylifolia could protect against bone loss.
Psoralea corylifolia (Babchi) is an important plant in the Indian Ayurveda and Tamil Siddha systems of medicine, and also Chinese medicine.
In the legume family (Fabaceae), species reported to produce tumbleweeds include some members of the genus Psoralea, and Baptisia tinctoria.
