The variety of Zishen was confused in the past records. Its original plant should be Polygonum bistorta. The crude drugs bearing the name of Zishen are varied presently. Their functions are completely different from what is recorded in "Benjing". Thus it is suggested that the name Zishen be discarded and replaced in "Quanshen".
