目前中药汤剂剂量不准确是普遍存在的问题,也是老大难问题。本人曾对一些处方剂量进行过差量称量,每剂药的重量因各味药分量不均匀而产生的差额一般在20～30g之间,最多可达50g,平均相对误差超过±10％(一般规定正负误差为±5％),可见病人吃了如此份量不均匀的汤药,治疗效果一定是大相径庭的。古人说:“中医不传之秘在用量上”。中药量的概念和配伍的概念同等重要。
At present, the inaccurate dosage of traditional Chinese medicine decoction is a common problem, and it is also a difficult problem. I used to have a number of prescription doses that are too badly weighed. The difference in the weight of each dose due to the non-uniform weight of the individual flavors is generally between 20 and 30g, and the maximum is 50g. The average relative error is more than ±10% ( Generally, the positive and negative errors are ±5%. It can be seen that the patient has eaten such a soup with a non-uniform amount of soup. The therapeutic effect must be very different. The ancients said: “Chinese medicine does not pass on the use of the secret.” The concept of Chinese herbal medicine and the concept of compatibility are equally important.
