[Cause and measure of short of quality control on Chinese medicine herbs].

Chinese medicine is short of quality control for three reasons. Firstly, near 90 percent Chinese medicine herbs are lack of quality standards and hard to be evaluated. Secondly, basal study falls behind relatively, which limites development speed of quality control and quality standard. Finally, Chinese medicine herbs haven't uniform refine operating norm. We must strengthen basal study, constitute the inspection norm of Chinese medicine herbs quality and establish perfect technical supervise system as fast as possible.

[Non-technical causes of fakes existing in Chinese medicinal material markets].

Non-technical causes of fakes existing in Chinese medicinal materials markets come from three aspects. Source of Chinese medicinal materials is complex and it is difficult to trace back to a source; lawless add impurities and use inferior goods pretending to superior quality and illegally seek for profit; supervising department lack strict blow and deterrent force is limitted.

[Study concept of traditional Chinese medicine quality standards].

Chinese medicinal materials quality was controlled mainly by modern analytic approach, secondly by traditional identification method, popularizing based on improvement. Chinese medicine prepared slice quality was controlled mainly by traditional identification method, secondly by modern analytic approach, improving based on popularization.
