由“石膏微溶而重用之”引发的三条术数猜想

Three conjectures of numerical divination from “gypsum is slightly soluble and used at a high dose”

生石膏在临床上被广泛应用于外感温热病以及内伤杂病的治疗,被誉为"降火之神剂,泻热之圣药"。众所周知,石膏微溶于水,为什么临床用药显示大剂量的石膏清热效果更好呢?笔者针对这一现象并结合现在关于石膏药用机制的研究,大胆提出三种猜想,即中药的化学成分不是药性惟一的作用基础、中药作用剂量不连续、石膏的剂量是分节点的。希望对中医临床思维有一定的启发意义,有助于加深广大中医学者对中医基本理论的认识程度,同时也为认识中医药提供新的方向。

Gypsum, known as ＂the prime Chinese medicine of decreasing internal heat＂ and ＂the effective herbal medicine of purging heat＂, is widely used in clinical treatment for exogenous febrile disease and endogenous miscellaneous diseases. It is well known that gypsum is slightly soluble in water. But clinical practice proved gypsum had better effect in clearing heat when used at a high dose. This article puts forward three hypotheses about the mechanism of this phenomenon： the chemical composition of Chinese medicine is not the only basis of its action, the dose of Chinese medicine is discontinuous, and the dosage of gypsum is divided into several nodes. These hypotheses would be of some significance to inspire the clinical thinking of traditional Chinese medicine （TCM）, deepen the understanding of the basic theories of TCM and provide a new direction for the understanding of TCM.
