Bergenin, alias cuscutin, is trihydroxybenzoic acid glycoside. It is the C-glycoside of 4-O-methyl gallic acid. It possesses an O-demethylated derivative called norbergenin. These are chemical compounds and drugs of Ayurveda, commonly known as Paashaanbhed. It shows a potent immunomodulatory effect.[1]

Bergenin can be isolated from Bergenia species like Bergenia ciliata and Bergenia ligulata,[2] from rhizomes of Bergenia stracheyi. It is also found in the stem bark of Dryobalanops aromatica,[3] in Ardisia elliptica and in Mallotus japonicus.[4]
