中医学对治疗痛经有完整的理论和宝贵的治疗验方,但目前基于这些验方所生产的中成药疗效不佳,甚至无效,不能体现原方汤剂的效果。从现代药效学及生物药剂学角度分析,其原因可能为药物的吸收速度慢、吸收程度差和服药时间不当。药物发挥治疗作用的前提条件是药物被吸收,吸收的速度及程度直接影响药物的血 Chinese medicine has a complete theory and valuable treatment prescriptions for the treatment of dysmenorrhea, but at present, the efficacy of Chinese traditional medicines based on these prescriptions is not good or even invalid, and the effect of the original decoction cannot be reflected.

The precondition for the drug to play a therapeutic role is that the drug is absorbed, and the speed and degree of absorption directly affect the blood of the drug.
