The Historical Development and Contemporary Value of the Fire-Toxin Removal Methods
The fire-toxin removal methods refer to techniques used to reduce the toxic heat properties of medicines.During the Qin and Han dynasties,alchemists gradually recognized the toxicity of mineral and metallic medicines as well as alchemical formulas.Based on practical experiences,they developed methods to remove fire-toxin,laying the foundation for future theories on this process.In the Wei,Jin,Sui,and Tang dynasties,alchemists emphasized the necessity of removing fire-toxin before alchemical preparations,leading to signif-icant changes in the proportions and efficacy of medicinal formulas.The use of"small elixirs"(non-metallic and non-mineral medi-cines)increased,and alchemical formulas began transitioning into medical formulas,thereby expanding the clinical application of fire-toxin removal methods.During the Song,Jin,and Yuan dynasties,these methods became standardized.In the Ming and Qing dynasties,elixirs began to be used in surgical applications,and the fire-toxin removal methods were also applied to external preparations such as decoctions,ointments,and plasters.In modern times,the fire-toxin removal methods are mainly used to reduce the toxicity of plasters and to detoxify medicines through specific processing techniques.The main methods include the earth-fire toxin removal method,water-fire toxin removal method,calcining and quenching fire toxin removal method;adjuvant-fire toxin removal method;comprehensive fire toxin removal method.These methods can enhance efficacy,alter medicinal effects,and reduce toxicity,having a profound impact on the processing of Chinese medicinals.
