Summary Of Professor Liu Ai-min’s Experience Of Treating Eczema Based On Syndrome Differentiation From “the Analysis Of Pathogenesis In Dampness-Heat”

Objective:To sum up the academic experience of Professor Liu Aimin in the syndrome differentiation and treatment of eczema,and to form a completed“principle-method-recipe-medicinal”system of Liu Aimin’s syndrome differentiation and treatment of eczema,which is convenient for academic exchange and experience inheritance.Method:1.Based on the study of literature,through the collation and study of the medical cases,courseware,works,theses and other materials of the tutor on eczema,the author summarizes Professor Liu Aimin’s academic experience in differentiation and treatment of eczema by using the traditional clinical research method of traditional Chinese medicine(TCM),and it is comprehensive-based analysis method,combines with typical medical cases to understand as well.2.With the help of the software TCM Inheritance assistance platform(V2.5),130 cases of eczema cured in Professor Liu Aimin’s clinic(including 298 formulas)were excavated,and his academic experience was extracted and corroborated from the rule of medication,with combining traditional research and modern research organically,in order to form Liu Aimin’s system of syndrome differentiation and treatment of eczema accurately.Results:1.Professor Liu Aimin held the view that the core pathogenesis of eczema was dampness-heat amassing in skin,and the source of dampness and heat mainly included four aspects,namely,external dampness,internal dampness,dampness neither internal nor external,and combined pathogens of internal and external.2.Professor Liu Aimin’s schemes of syndrome differentiation and treatment of eczema of the analysis of pathogenesis in dampness-heat were as follows:①The etiology and pathogenesis belonged to wind-cold fettering exterior and dampness-heat amassing in skin,the treatment method was to ventilate lung and dissipate cold,remove dampness and clear heat,and the prescription was Modified Mahuang Lianqiao Chixiaodou Tang(Decoction of Ephedra,Weeping Forsythia Capsule and Adzuki Bean).②The etiology and pathogenesis were yang deficiency and external cold,the treatment method was to warm yang and ventilate lung to resolve dampness,and the prescription was Modified Mahuang Fuzi Xixin Tang(Decoction of Ephedra,Aconite and Asarum).③The etiology and pathogenesis were dampness-heat amassing in skin,the treatment method was to remove dampness and clear heat,and the prescription was Modified Longdan Xiegan Tang(Decoction of Gentian for Purging Liver Fire)or Modified Bixie Shenshi Tang(Decoction of Collett Yam for Eliminating Dampness).④ The etiology and pathogenesis belonged to spleen deficiency and dampness amassment,the treatment method was to invigorate the spleen and remove dampness,and the prescription was Modified Shenling Baizhu San(Powder of Ginseng,Poria and Bighead Atractylodes)and Modified Chushi Weiling Tang(Decoction of Stomach-Calming and Five Ingredients with Poria for Removing Dampness).⑤The etiology and pathogenesis were wind-heat dampness invading skin,the treatment method was to disperse wind and clear heat,cool blood and remove dampness,and the prescription was Modified Xiaofeng San(Powder for Dispersing Wind).⑥The etiology and pathogenesis were dampness and blood stasis block and skin loss of nourishment,the treatment method was to reinforce qi and activate yang,remove dampness and activate blood circulation,and the prescription was Modified Huangqi Guizhi Wuwu Tang(Decoction of Astragalus and Cinnamon Twig Five-Substance).3.Professor Liu Aimin’s thoughts on the treatment of eczema were as follows:①For those with eczema and herpes,use dissipating with pungent-warm method;②For those with eczema in winter,pay attention to the application of warming method;③For those with eczema on the hands and feet,pay attention to invigorating the spleen and removing dampness without forgetting to clear the yang;④For those with eczema and dry skin,use moistening with acridity method to moisten the skin.4.The experience of learning from teachers was as follows:①The tutor adhered to the clinical thinking of TCM;②He was good at using an analysis of pathogenesis in syndrome differentiation model;③He was adept at using the theory of Huangdi’s Internal Classic;④Accurately obtaining the information of four diagnoses was the key to the analysis of pathogenesis in dampness-heat;⑤The recording and management of medical cases should be paid attention.5.After the analysis,Liu Aimin’s rule of medication in the treatment of eczema were as follows:①Warm-cold medicine is the main medicine,with the frequency ratio of warm-cold medicine being 1.28;②The medicines were mainly bitter,pungent and sweet,accounting for 98.6%,and the ratio of the three kinds of drug-flavor was close to 1:1:1;③The medicines mainly enter lung meridian,spleen meridian,stomach meridian and bladder meridian;④The prescription drugs were mostly 12 or so,and the prescriptions were refined.6.The medicines used more than 90 times included:Huangbo(Cortex Phellodendri Chinensis),Baixianpi(Cortex Dictanni),Fangfeng {Radix Saposhnikoviae),Cangzhu(Rhizoma Atractylodis),Yiyiren(Semen Coicis),Chenpi(Pericarpium Citri Reticulatae),Chaihu(Radix Bupleuri),Gancao(Radix et Rhizoma Glycyrrhizae),Mahuang(Herba Ephedrae),Huangqi(Radix Astragali),Fuling(Poria),Chixiaodou(Semen Phaseoli),Guizhi(Ramulus Cinnamomi),etc.There were common drug combinations as followed:①Huangbo and Baixianpi;②Huangbo and Yiyiren;③Huangbo and Cangzhu;④Baixianpi and Cangzhu;Huangbo and Fangfeng,etc.Common couplet medicines included:Fuling—Danggui(Radix Angelicae Sinensis),Houpo(Cortex Magnoliae Officinalis)—Ganjiang(Rhizoma Zingiberis),Fuling—Baibiandou(Semen Lablab Album),Chaobaizhu(Bighead Atractylodes)(baked)—Mahuang,Cangzhu—Gancao,etc.Core drug combinations included:Muli(Concha Ostreae)—Chaihu—Huangqi,Huangqin(Radix Scutellariae)—Chuanniuxi(Radix Cyathulae)—Wugong(Scolopendra),Zhigancao(Radix et Rhizoma Glycyrrhizae Praeparata cum Melle)—Gancao—Yiyiren,Jingjie(Herba Schizonepetae)—Fuling—Fangfeng,Baishao(Radix Paeoniae Alba)—Huangbo—Shengjiang(Rhizoma Zingiber is Recens),etc.The new formulas were as followed:①Muli,Chaihu,Huangqi,Sharen(Fructus Amomi),Baibiandou;②Huangqin,Chuanniuxi,Wugong,Shanyao(Rhizoma Dioscoreae),Jineijin(Endothelium Corneum Gigeriae Galli);③Zhigancao,Yiyiren,Huangbo,Dazao(Fructus Jujubae);④Jingjie,Fuling,Fangfeng,Zhifuzi(Radix Aconiti Lateralis Praeparata),Mahuang;Baishao,Huangbo,Shengjiang,Zhigancao,Dazao,etc.Conclusion:Based on the clinical thinking of the TCM such as harmony between man and nature,cure for the root,concept of holism and syndrome differentiation and treatment,Professor Liu Aimin takes the dampness-heat amassing in skin as the core pathogenesis,and explores the source of dampness-heat with the thinking of syndrome differentiation of season,viscera,meridians and collaterals,as well as body parts,which is an analysis of pathogenesis in syndrome differentiation.And he selects drugs and form formulas according to the etiology and pathogenesis,finally forming a completed principle-method-recipe-medicinal system of Liu Aimin’s syndrome differentiation and treatment of eczema.
