Botanicals contain phytosteroids that bind non-estrogen steroid receptors. Kaempferol, apigenin, and genistein bind progesterone and androgen receptors. Ginsenoside Rf and glycyrrhetinic acid interact with corticoid receptors. Compound A is a novel selective glucocorticoid, based on a phytosteroid. Characterization of phytosteroids will help elucidate their safe and effective use.
