浅议加热对中药寒热药性的影响

A Brief Discussion on the Effect of Heating on the Cold and Heat Properties of Chinese Medicine

寒热药性是中医临床用药“疗寒以热药,疗热以寒药”的理论依据,其与临床疗效关系十分密切。然寒热二性易受生长环境、药物剂型、使用方法等诸多因素影响,如汤剂煎煮、加工炮制、制剂工艺等环节均对其影响较甚。无论是传统理论文献,还是现代科学研究成果,均表明寒热药性在汤剂制备、炮制加工、制剂生产过程中随着受热条件的变化其药性会发生转化,以热制寒,使其寒凉之性逐渐减弱,甚者药性由寒转温;或以热助热,温热之性更加浑厚。因此笔者提出“久煎助温、久热助温”的理论假说,为中药汤剂煎服、加工炮制、制剂生产及中药临床合理应用提供一定的理论参考。

Cold and heat properties are the theoretical basis of clinical medication of Chinese medicine,which are closely related to clinical therapeutic effect. However, cold and heat properties are easy to be affected by many factors such as growth environment,preparations of medicine and method of application, and for example, the process of decocting, processing and preparation have a great effect on them. Both ancient theoretical literatures and modern scientific researches indicate that cold and heat properties can be transformed with the change of heating conditions during the process of decocting,processing and preparation. If the medicine of cold property gets heated, its cold and cool properties gradually get weakened, and what is worse is that the property of medicine turns warm from cold;if the medicine of heat property gets heated,its heat property gets strengthened. Therefore,the authors put forward the theoretical hypothesis of " long time of either decocting or heating strengthens the warm property", which provides certain theoretical reference for the process of decocting,processing and preparation as well as the rational application of Chinese medicine in clinic.
