Chinese medicine was known as old as chinese history. In Taiwan, people have already paid attention to the importance of Chinese drugs for quite a long time. Most of Chinese medicine can be made of and extracted from natural plants, animals and minerals. The lesser but important use of mineral ingredient in drugs has been already known in Asian areas, especially Mainland China. So the purpose of this study is to preliminary understand the mineral species and its accepted content of medical ingredients from minerals or materials both in Chinese medicine market and Taiwan mineral deposits. The key results of the present study show that Pb content from pyrite and kaolinite ingredients in Taiwan mineral deposits are 133.1 ppm and 40.63ppm respectively, which are somewhat higher than 30ppm in medical ingredients regulated by the government. Meanwhile, Pb contents in Hanshuishi and Baishilying samples collected from domestic Chinese drugstore are also a little higher than the figure of accepted limit. In addition, Cd contents of pyrite and calcined lime from mineral deposit in Taiwan. a little exceed the 2ppm permit limits. Pyrite from mineral deposits contains 98.87ppm of Hg which is extremely higher than 2ppm maximum permitted concentration. In conclusion, both pyrite、kaolinite and calcined lime from mineral deposits in Taiwan are not suitable for use as mineral ingredient in drugs.
