title: Development of natural crude drug resources from Taiwan (X). Pharmacognostical studies on the Chinese crude drug "han-lian-cao".
abstract: In a previous paper(1), it was reported that the drug "Han-lian-cao", in Taiwan was derived from the entire plant or aerial part of Eclipta prostrata L. and Alternanthera sessilis R. Brown. In this paper, the histological studies of "Han-lian-cao" derived from Wedelia and Hypericum plants, and of 3 species of Wedelia related plants distributed in Taiwan were made. The results showed that it was possible to classify these species by their external and internal characteristics. In addition, a key to the characteristics of the whole plants of Eclipta, Alternanthera, Wedelia and Hypericum plants are hereby given.
