RemarksThere are two commodities in the market now. One is "Ziwan (Ruanziwan)" and the other is "Shanziwan (Yingziwan)". The real "Shanziwan" is the subterranean part of Ligularia fischeri Turcz.(Jap. name: Otakarako) and other species of family Compositae. Though there are other "Ziwans" which originate form family Ranunculaceae, Rosaceae, Liliaceas, etc., they are fake.
