中药能防病治病,也能致病。有些人认为,服中药安全,常服多服没有关系,因为中药汤剂大多是变方,药物可互相制约,不会产生不良反应,实际上这种认识是片面的。尽管中药大多是植物、动物类药物,性质平和,毒性较小,如果用药不当,或病人体质过敏,或药量过大,或配伍不当等,同样可以产生各种不良反应及中 Chinese medicine can prevent and cure diseases and can also cause diseases. Some people think that taking Chinese medicine for safety is not related to regular service and more services because Chinese herbal decoctions are mostly variants. Drugs can restrict each other and do not produce adverse reactions. In fact, this understanding is one-sided.
