Menispermaceae is a family of flowering plants. The alkaloid tubocurarine, a neuromuscular blocker and the active ingredient in the 'tube curare' form of the dart poison curare, is derived from the South American liana Chondrodendron tomentosum. Several other South American genera belonging to the family have been used to prepare the 'pot' and 'calabash' forms of curare. The family contains 68 genera with some 440 species, which are distributed throughout low-lying tropical areas with some species present in temperate and arid regions.
Stephania is a genus of flowering plants in the family Menispermaceae, native to eastern and southern Asia and Australia. They are herbaceous perennial vines, growing to around four metres tall, with a large tuber. The leaves are arranged spirally on the stem and are peltate, with the leaf petiole attached near the centre of the leaf. The name Stephania comes from the Greek, "a crown". This refers to the anthers being arranged in a crown-like manner.
