Man Kyung Dan(萬經丹) is a Chinese patent medicine which has been used for rheumatic neuralgia, apoplexy, extremitas neurolepsis in Korea. It consists of 16 kinds of powdered crude drugs. In powered crude drugs, it is hard to identify each component by chemical analysis or morphological examination. However, the method of identification of powdered crude drugs has not been clearly established. For the identification of individual crude drugs in such powdery mixtures, microscopic method may advantageously be used, as it requires only small amount of specimens. In this study, it is demonstrated that the microscopic method is very effective for the identification of 16 crude drug ingredients in Man kyung Dan.
