目前,中药材同名异物,同物异名的情况相当普遍,如白头翁有23种,贯众有29种。这种混乱情况严重影响了临床用药的效果,故必须建立“标准药材”,才能鉴别药材的真伪优劣,保证中药材的质量。有些地方虽有药材的标准品,但他们的“标准药材”并不标准。原因是这些标本大多由各单位自行采集或收集,仅经外形鉴别相符后便收作正品标本,一般不再做进一步的确证。这样,就使标本的可靠性受 At present, the names of foreign bodies with the same name as traditional Chinese medicines are quite common, such as 23 species of Pulsatilla and 29 species of Guanzhong.
