Bergenia ligulata Rhizome Source & Identity
The botanical entity is Bergenia ligulata (Wall.) Engl., a hardy perennial of the saxifrage family, Saxifragaceae, found on rocky slopes of the Himalayan region. The part used is the thick, fleshy rhizome. The large rounded leaves, flower stalks and thin roots are not part of this bergenia ligulata extract.
The name is unstable in databases. GBIF lists B. ligulata as a synonym of Bergenia pacumbis, so literature may use either name. Other bergenias, such as B. ciliata, B. crassifolia and B. stracheyi, are separate species with their own trade names.
The rhizome carries the C-glycoside bergenin, together with tannins, gallic acid and catechins.
