The background,present situation,problem and tactics of GAP of chinese materica medica / 药学实践杂志

In this paper,the background,present situation,problem and tactics of GAP(Good Agricultural Practice)of chinese materia medica are discussed.The main problems of the yielding of chinese materia medica are as followings:(1)Lack of close controlling standards and scientific detecting methods.(2)Decentralized management.low benefit and low controllability.(3)The pesticide residue and heavy metal content exceeding the provided standard.(4)Production and marketing disjointed,supervising and controlling intensity in the whole yielding process not enough.Thus,3 measures are put forward:(1)Strengthening the management of the quality of chinese materia medica,formulating strict and unitary quality controlling standards,setting up scientific checking methods.(2)Developing genuine drugs,establishing famous brands.(3)Establishing green chinese meateria medica yielding bases,to make the Chinese Materia Medica utilization sustainable.
