[History and development of carbonization of Chinese materia medica and exploration on its mechanism of hemostatic action].

The first material recorded about hair charcoal is seen in Nei jing (Inner Canon). It has a history of over 2 000 years for the carbonization of Chinese materia medica. There were controversies on this matter and its clinical application was seldom seen and underdeveloped. After the Yuan Dynasty, the main theory of carbonic herbs for hemostasis, and keeping the nature of the medicines after carbonization was gradually formed, and physicians of generations began to conduct in-depth research. Through repeated practice and verification, people summed up the suitable species of Chinese materia medica and its principle for carbonization. The methods and degree of carbonization of Chinese materia medica are reasonably discussed, with its principle and basis for application primarily interpreted.《内经》首次记载头发烧炭，中药制炭已有2 000多年的历史。宋代以前中药制炭的品种和应用存在较大争议，临床应用较少，发展缓慢。元代以后逐渐形成炭药存性、炭药止血的主要理论，历代医家进行了广泛深入的研究，经过反复实践验证，总结出适合中药制炭的品种、原理和临床应用，对中药制炭的方法、程度进行了合理的论述，初步解释了中药制炭的原理和应用依据。.
