Method for the identification of powdered crude drugs, when not mixed with other crude drugs, has already been established. However, many of the Chinese patent medical preparations often include mixtures of several powdery crude drug ingredients. For the identification of individual ingredients in such powdery mixtures, microscopic method may advantageously be used as it requires only a small amount of specimens. In this paper, effectiveness of this method will be exemplified by the identification of the ingredients in niuhuang shangqing wan (牛黄上清丸) which contains 19 powdered crude drug ingredients.
