[Identification of Chinese traditional drug luoshiteng and some obscure of its species]

A comparative identification of Luoshiteng and some of its obscure species has been made, and an identification key of characters of crude drugs has been compiled. It is pointed out that the drug described under the item of Luoshiteng in the Chinese Pharmacopoeia (1990) is a mixture of Luoshiteng and Shixue (Trachelospermum jasminoides var. heterophyllum).
