Main books and academic thoughts:
Herbalist 許叔微(Xǔ Shūwēi) was admitted as one big scholar in the academic field of Shang Han Lun during the Song Dynasty, he proposed many detailed interpretations, supplement with the syndrome differentiation and treatment theory, he said that: “the treatment of cold-induced disease, should be clear with interior and exterior, excess or deficiency. As long as know the meaning of these, the 397 methods of herbalist Zhang Zhongjing, could be used easily.” Herbalist Xu Shuwei often help to treat strange disease and difficult case, and say farewell for thanks, ever made excellent study with the theory of the exogenous febrile disease, emphasized that the importance for the treatment of exogenous febrile disease is the identification of the deficiency, excessive, cold and heat. And later he compiled related works include Shang Han Bai Zheng Ge, Shang Han Fa Wei Lun, Shang Han Jiu Shi Lun, etc, devoted to the development of the exogenous febrile disease study, not only inherited the thought of ancient herbalist Zhang Zhongjing, also gave further interpretations. His main interpretations on Shang Han Lun and treatment of cold-induced disease are introduced:
⑴.The key to the syndrome differentiation of the cold-induced disease is the differentiation of the exterior and interior, the deficiency and excess. This conclusion was recorded in his book Shang Han Bai Zheng Ge(the hundred syndromes songs of the exogenous febrile diseases), and he summarized and pointed out four types of syndromes with four types of recipes, and pointed out different types of recipes are for different types of syndromes, he summarized the prescriptions of Shang Han Lun with exterior interior and deficiency excess, this is a further development and interpretation of Zhang Zhongjing's differentiation based on six-meridian syndrome differentiation, he also proposed the syndrome differentiation based on exterior interior and deficiency excess, should combine with Yin and Yang, cold and heat; the points for syndrome differentiation of doubtful cold and heat syndrome, should refer to the synthetic analysis of pulse and syndrome; these discussions and interpretations had influences on the later establishment of the differentiation of eight principles.
⑵.The emphasis on the importance of the Primordial Qi in the treatment of cold-induced disease, as herbalist Xu proposed "in cases of the cold-induced disease, whatever Yin syndrome or Yang syndrome, Yin toxin or Yang toxin, the key point is that it is easy to treat for the case with strong Primordial Qi, it is difficult for the case with weak and deficient Primordial Qi.", this conclusion came from his practice.
⑶.The development of the "affection from deficiency" pathogenesis theory of Nei Jing(the Inner Canon): "the pathogens accumulated, the Qi is surely deficient." is an important pathogenesis theory from the ancient book Nei Jing(the Inner Canon), herbalist Xu proposed that the endogenous pathogenic reasons are more due to deficiency of the healthy energy, but once affected by the pathogens and the pathogens are detained, the nature of the disease normally develops with changes of excess, thus, herbalist Xu pointed out that treatment should follow the principle "eliminate the pathogens firstly, invigorate secondly", herbalist Xu not only applied the prescriptions of Zhang Zhongjing flexibly, he also created new prescriptions to dispel the pathogens.
⑷.Interpretation on the pulse methods of Zhongjing, herbalist Xu attached great importance on the pulse manifestations, and he proposed that "To treat the cold-induced disease, should be based on the pulse methods of Zhongjing.", and he summarized the complicated pulse manifestations with principles of Yin and Yang, to tell the good or ill luck, and the prognosis, then sum up various pulse manifestations, differentiate the exterior interior deficiency excess with pulse floating or deep, powerful or weak, differentiate the location in the Zang viscera or the Fu viscera with rapid pulse or slow pulse, and make it clear and flexible for applications. Herbalist Xu also pointed out the difference of pulse manifestations between cold-induced disease and miscellaneous diseases, summarized common pulse manifestations of the cold-induced disease, for examples, floating and slow is the pulse manifestation of Zhongfeng(wind affection), floating, uneven(hesitant) and tight is the pulse manifestation of Shanghan(cold affection), floating and rapid is the Yang pulse of Yang syndrome, string-like, slow pulse, with the coldness of hands and feet is the pulse of Shao Yin syndrome, etc, he pointed out characters of cold-induced diseases and made it easier for disciples to learn. Herbalist Xu also emphasized the diagnosis of Ren Ying, Cunkou, FuYang, TaiXi, and pointed out that "The Cunkou of the right hand is main for Qi, the RenYing is main for blood. The Cunkou is tight then it is surely hurt from the diet, the Ren Ying is tight then it is the severe case of wind affection", "the Fuyang stomach pulse determines life or death, the Taixi kidney pulse is the root and base.", the first conclusion has values for differentiation between exogenous wind affection and endogenous hurt from diet and drink, the second conclusion has special values for the prognosis of diseases. He also pointed out that although the diaphoresis, emesis, and purgative methods are big methods for the treatment of the Shanghan(cold affection), they are only suitable for excess type syndromes, should never be used for syndromes of the deficiency type. Thus, he also pointed out that "In case the pulse is weak and big, should avoid leading to vomiting; To use the purgative method should avoid case feeble and thready pulse; In case the pulse is deep and weak, weakness of Qi, it is difficult to induce sweating; These three principles should be remembered carefully.", this is really a summarized conclusion from experiences. Besides, he also attached great importance to the varies of pulses, to differentiate the development, transmission or not, and prognosis of the diseases, and he proposed that "the case pulse nine arrives in one breath, it is the case the essence and Qi are collapsing, the chaos of spirit and Qi, should be saved immediately; case pulse nine to ten arrives in one breath, as flowing out of the spring water, the pulse has no Qi flowing inside, it is the case collapse of the Primordial Qi, surely are symptoms of dying.", and he also has many other intensive and profound conclusion of pulse manifestations based on learning of Zhongjing's pulse theory and his own experiences from practice.
⑸.Interpretations and summarization on the applications of the cold-induced syndromes and prescriptions: herbalist Xu not only has an in-depth study of the syndrome differentiation, pulse manifestations of Shang Han Lun but also has many developments and innovations. His related works Shang Han Jiu Shi Lun recorded 61 cases of the cold-induced disease, listed pulse manifestations and syndromes according to the entries and articles of the book Shang Han Lun strictly, and these cases all proved the precise effects of those prescriptions and syndrome differentiations from Zhongjing's theory. He also uses the prescriptions flexibly, for example, his prescription for the heat invading the blood chamber syndrome of woman, etc. For those syndromes with no listed prescriptions in Shang Han Lun, he often collected other medical works include Nei Jing, Nan Jing, Qian Jin Yao Fang, Wai Tai Mi Yao, and supplement it syndrome with a relevant prescription, to guide the practice. Except for the flexible applications of Zhongjing's prescriptions, herbalist Xu also summarized Zhongjing's theories: for example, he summarizes the Taiyang-Yangming combined syndrome as (1st). The case diarrhea is the syndrome of decoction Ge Gen, (2nd). The case vomit throws up but no diarrhea is the syndrome of Ge Gen Jia Ban Xia, (3rd). The case panting and fullness in the chest is the three syndromes of mahuang decoction, he also summarized the Tai Yang Zhong Ye syndrome as three types, (1st).The case sweating and aversion to cold, heat of the body and thirst, is the case of Tai Yang Jing Zhong Ye, (2nd). The case fever and aversion to cold, pain of the body, the pulse is string-like thready gaseous(hollow) and late, (3rd). The case gets hurt of cold water in summer, water flow in the skin, the heat of the body, heavy pain and ache, the pulse is weak and feeble; His summarization crystallized the theory of Zhongjing, and provide a clear, exact theoretical basis for practice, he also summarized and classified Zhongjing's methods include diaphoresis, emesis, purgation, fire, water, acupuncture, moxibustion, analyzed and listed them in orderliness, provided convenience for later generations to study the theory of Shang Han Lun, and these represented his correct and penetrating views of Shang Han Lun.
⑹.Interpretations on the prescriptions and application of Shang Han Lun: herbalist Xu has fine discussions on the prescription applications of Shang Han Lun, he connected and combined the pathogenesis and interpretations from previous herbalist Wang Shuhe and Sun Simiao, and has his own specific creative opinion on the three main types of the Tai Yang syndromes, as he explained: the pathogenesis of the wind affection(Zhongfeng), the pathogenesis of cold affection(Shanghan), in case observed cold pulse in case of the wind affection(Zhongfeng), or wind pulse in case of the cold affection(Shanghan), is the case wind and cold doublely hurt the Ying and Wei system. His interpretations made the three outlines from herbalist Wang Shuhe and Sun Simiao clear and distinct, have a big influence on later herbalists. Besides, herbalist Xu also has his special opinion on the applications of decoction and pills from Shang Han Lun, and proposed his principle that "the treatment of cold-induced diseases, pills should be used cautiously."; He also pointed out the difference between the white peony root and red peony root in applications, the difference between the Gui Zhi(cassia twig) and Rou Gui(the cinnamon bark), he agrees with herbalist Wang Shuhe's opinion on "the Dachaihu decoction, not use the Dahuang, is a mistake", and emphasized that "although Dahuang is a general herb, but to eliminate the accumulated heat, dispel old retentions, it is a key herb in Shang Han", should use it properly. He also proposed that "the croton seed only dispel food retention but could not eliminate heat toxins", should void using it for the case of endogenous heat toxin accumulation. These theses and discussions are very apt to practice, generated a big influence on the later applications of Zhongjing's prescriptions.
Except for interpretations on Shang Han Lun and treatment of the cold-induced diseases, herbalist Xu also has academic achievements on the treatment of miscellaneous diseases, attached importance on the aspect of life activities and pathological functions of the spleen and stomach, master in ancient prescriptions, create new prescriptions, these interpretations are briefly introduced:
⑴.Studies and interpretations on the theory of the spleen and stomach: herbalist Xu attached great importance to the important functions of the spleen and the stomach viscera. As he repeatedly pointed out in his works(Pu Ji Ben Shi Fang, Shang Han Bai Zheng Ge) that the spleen and stomach closely related with life and death. Thus, in severe cases, should take pulse of Taichong to see the state of the stomach Qi, take pulse of Taixi to see the sufficiency or deficiency of the kidney Qi, if the state is not good for these two pulses, mostly are cases of syndrome with unfavorable prognosis, and symptoms of case in danger. Besides, herbalist Xu also set up proper methods for related syndrome and with his famous prescriptions, include Ren Cen Pills, etc, and they all have good effects for related syndromes. He also has other creative methods and prescriptions for the treatment of kidney deficiency syndromes, and syndromes of spleen and kidney deficiency.
⑵.Creative innovations on syndrome differentiation and treatment of endogenous wind: herbalist Xu has many creative conclusions on the differentiation and treatment of endogenous wind syndrome, and recorded in his book Pu Ji Ben Shi Fang, had great enlightenment to later generations. He classified the wind affections as 3 major types, known as (a).wind affection the channels, (b).wind affection the Fu viscera, (c).wind affection the Zang viscera. He recorded general and exact symptoms of the wind affection with channels, Zang-viscera and Fu-viscera, and established related principles of treatment. He also suggests treating wind affection with moxibustion and listed out 12 acupoints special for it. He also analyzed the pathogenic reasons of palpitation syndrome due to fear, and established a method to treat it.
⑶.Herbalist Xu is also good in the treatment of miscellaneous disease, for example, accumulation and mass, numbness syndromes, pain and ache syndromes, etc. He often uses a method known as Sou Ti Qu Xie Fa(sourcing and kicking dispelling method), use prescriptions majorly composed of insects and worms, include scorpion and earthworms, etc, to free the meridians and relieve pains. And he also pointed out the proper applications and proper insect herbs for various accumulation and retention syndromes.
⑷.Herbalist Xu is also good in the application of ancient prescriptions with flexibility and modifications, create new prescriptions, his book Pu Ji Ben Shi Fang recorded over 370 kinds of prescriptions, some of them came from ancient famous medicine books Qian Jin Fang, He Ji Ju Fang, Bi Yong Fang, Huo Ren Shu, Qian Jin Sui, Jing Xiao Chan Bao, Wan Jin Fang, some came from ancient famous herbalists and Taoist(include Pang Anshi, Sun Zhao, Yang Jilao, Shen Kuo, Cai Taishi, Zhang Changshi, Chao Tuiguan, Zheng Kangde, Cui Yuanliang, Tian Zi, Zhenxin taoist, etc.), herbalist Xu classified the effective prescriptions he collected into different entries under title five Zang viscera syndromes, recorded syndromes and listed prescription, supplement with notes of its origin, or records about its efficacy. Thus, herbalist Xu had done a good reservation and inherit the valuable experience from previous professionals and kept precious history literature for later generations. Except for his reservation work, herbalist Xu also attached importance on the modification of ancient prescriptions and those prescriptions from Shang Han Lun, get good efficacy in practice. He also creates new prescriptions for wide applications, some of them are known to include Qi Zhen San, Qu Mu Yuan, Mi Rong Yuan, Er Shen Yuan, Jing Qi Yuan, Xiong Qiang Tang, etc. These prescriptions have many influences on later generations.
The three major books with topics on Shang Han Lun from herbalist Xu, known as the Shang Han Bai Zheng Ge in 5 volumes, Shang Han Fa Wei Lun in 2 volumes, Shang Han Jiu Shi Lun, were revised, printed and published widely in the 18th and 19th centuries, these books got known widely and became popular, ever since then, the academic values of these books from herbalist Xu got sufficient confirmation in the fields of TCM, herbalists admitted that he is one representative herbalist of the Song Dynasty with great achievement in the interpretation and application of the theory from Shang Han Lun, he was admitted as one outstanding and prominent herbalist in the development of TCM, his theory and experiences still have important guiding functions and practical values for today's practice.
His major works and books: Herbalist Xu Shuwei compiled many works in his life, his works known include Ben Shi Fang(or Lei Zheng Pu Ji Ben Shi Fang) in 10 volumes, Shang Han Bai Zheng Ge in 5 volumes, Shang Han Fa Wei Lun in 2 volumes, Shang Han Jiu Shi Lun, Zhi Fa, Bian Lei, Yi Shang Han Lun, Zhong Jing Mai Fa San Shi Liu Tu, Xu Ben Shi Fang in 10 volumes, etc. Among them, the content of the book Shang Han Bai Zheng Ge is in the form of rhymes style to present the theory of Zhang Zhongjing in 100 syndromes, for the convenience to study, in the case "syndrome without prescriptions", then supplemented with other prescriptions from classics include Qian Jin Yi Fang, etc; in the case the discussion was not sufficient, supplemented with theory and discussions from Chao Shi Bing Yuan, and quotations from other herbalists include 朱弘(Zhu Hong), 孫尚(Sun Shang), 孫用和(Sun Yonghe), etc. The classics Shang Han Fa Wei Lun recorded a totally 22 discourse on prescriptions, the first discourse listed the 72 syndromes of the exogenous febrile disease, gave detailed interpretations, the second discourse and following gave records of the author's viewpoints. The content of the book Shang Han Jiu Shi Lun starts with the syndromes and symptoms, treatment procedure, and comments, similar to later medical records. The Lei Zheng Pu Ji Ben Shi Fang is an academic work and it recorded the clinical experience of herbalist Xu himself for passing on, it classified diseases into 23 parts, collected over 300 prescriptions, listed with main indications, prescription name and doses firstly, then recorded treatment method, instructions, attached with 1 to 2 cases, added comments in the end. Many of his specific viewpoints are insightful, for example, the Qi syncope should not be treated as symptoms of apoplexia, to invigorate the kidney better use nourishing herbs, differentiation with hemorrhoidal hemorrhage, bloody stool, blood hemorrhoids, etc. Later wise herbalist commented very highly of his achievement, for example, later herbalist 叶桂(Yè Guì) commented on herbalist Xu: "He was a scholar and professional in treatment. He holds a will for universal relief, and interpret secret from ancient herbalists, to benefit offsprings, a great achievement.", his theory and prescriptions showed a big and far influence on generation herbalists of the Song Dynasty and later.
Herbalist Xu Shuwei also ever compiled herbal classics Lei Zheng Pu Ji Ben Shi Fang(the Effective Prescriptions for Universal Relief, in 10 volumes) in his late, published, it was known briefly as Pu Ji Ben Shi Fang. The herbal classics Pu Ji Ben Shi Fang recorded herbal recipes over than 390 pieces, provided comparatively reliable identification and differentiation method for many syndromes with similarity, in a specific theory, herbalist Xu proposed his special viewpoint for the relationship of spleen and kidney in details, this theory had its important influence on visceral manifestation theory of later generation. He laid important emphasis on the relationship between the spleen and kidney, his viewpoint showed it enlightenment to later generation for further study with spleen-kidney relationship and clinical practice.
Among his works, Shang Han Bai Zheng Ge(the one hundres syndromes poem of the Treatise on Cold-induced Diseases) in 5 volumes, Shang Han Fa Wei Lun(the Elaborations on the Treatise on Cold-induced Diseases) in 2 volumes, Shang Han Jiu Shi Lun(the ninety treatises on the Treatise on Cold-induced Diseases), Lei Zheng Pu Ji Ben Shi Fang(the Effective Prescriptions for Universal Relief) survived till today, his other works lost in ancient time, and those books were known as Zhong Jing Mai Fa San Shi Liu Tu(the thirty-six graphs on the pulse formula of Zhongjing), Yi Shang Han Lun(there supplement wings of the Treatise on Cold-induced Diseases), Shang Han Lei Lun(the categorized Treatise on Cold-induced Diseases), Zhi Fa Ba Shi Yi Pian(Zhi Fa, or the Eighty-One articles on treatment methods), Bian Lei in 5 volumes, etc. These books are identified from herbalist Xu Shuwei himself, there is an ancient book Xu Ben Shi Fang(Supplement of Effective Prescriptions for Universal Relief) in 10 volumes, it attributed its authorship to herbalist Xu Shuwei too, yet the contents and academic viewpoints of some applications have some differences from herbalist Xu Shuwei which presented in his book Lei Zheng Pu Ji Ben Shi Fang(the Effective Prescriptions for Universal Relief), so the book Xu Ben Shi Fang is suspected as a doubtful ancient book forged its author to herbalist Xu Shuwei, but not his book.
The book Shang Han Bai Zheng Ge(the one hundres syndromes poem of the Treatise on Cold-induced Diseases) in 5 volumes, is his book mainly about the syndrome differentiation outline of the cold-induced diseases, syndromes, and symptoms, prescriptions. The 1st and 2nd volume are formulas in verses about the general principles of the syndrome differentiation of cold-induced diseases, the 3rd to 5th volume are formulas in verses about the syndromes of cold-induced diseases. It collects over 100 verses in easy and understandable common sentences, based on the author's in-depth study of the ancient works Shang Han Lun, main subjects are about exterior and interior, Yin and Yang, pain in the throat, Huo luan, vomit and throw up, fullness in the abdomen, spontaneous sweating, pulse manifestations, disease involving two or more channels, disease of one channel involving another channel, therapy, etc. With annotations and reference quote from ancient works Zhu Bing Yuan Hou Lun, and theories from herbalist Zhu Gong, Sun Yonghe, Pang Anshi, Song Di, Wang Shi, gave supplement and elaboration, with his own experience and theories from many years study of the works Shang Han Lun, to benefit later generations. It set the exterior-interior and deficiency-excess as an outline for the syndrome differentiation of the cold-induced diseases, also boost the spread and popularization of the works Shang Han Lun and its syndrome differentiation methods, it stated essential meanings from the works Shang Han Lun.
The book Shang Han Fa Wei Lun(the Elaborations on the Treatise on Cold-induced Diseases) in 2 volumes, collected his 22 academic articles, the 1st article listed 72 syndromes of the cold-induced diseases, explained and interpreted the pathogenesis, experiences of syndrome differentiation and prescriptions, the 2nd and later articles collected short articles of the author about own viewpoints about notes, discussions, for example, the difference of white peony root and red peony root in the Gui Zhi decoction, the differences of the Gui Zhi and Rou Gui, the importance of Primordial Qi in the cold-induced diseases, etc. Its contents are mainly from experiences of the author on the study of the cold-induced diseases, include syndromes and symptoms, pulse method, treatment, and prescriptions, etc, in fine details.
The book Shang Han Jiu Shi Lun(the ninety treatises on the Treatise on Cold-induced Diseases) collected 90 cases from the author's practice, among them there are 61 cases is about the classical cases originated from the works Shang Han Lun, related with 36 types of classical prescriptions. Each case recorded the syndromes and treatment procedure, followed by pathogenesis interpretations according to ancient works Nei Jing(the Inner Canon), Nan Jing(the Difficult Classic), Shang Han Lun(the Treatise on Cold-induced Diseases) and other relevant works, combined with the author's viewpoint, is an early consilia, and an important reference book to study the works Shang Han Lun.
There is a legendary story about herbalist Xu Shuwei for treatment with himself when he was young and studied very hard, he holds a habit of drinking wines before rest, years later, he often felt sounding in the stomach, and hypochondriac pain, the diet is reduced, vomit out some gastric juice every 10 days or half month, when summer comes, the left side of his body does not sweat, only the right side perspire. He made a careful analysis of his own case, and hold a viewpoint that the disease is due to dampness obstacle the stomach, the spleen and stomach are hurt, the spleen is deficient and water could not be transformed, caused dampness obstruction in the stomach, thus caught the internal dampness syndrome which appears with symptoms include sounding in the stomach and sweat on right body side only, vomit gastric juice, etc. Thus, herbalist Xu tried to treat himself and followed his academic thought "medication in essence", prepared a special pill for it, took 50 pills daily, and increased to 100 to 200 pills daily gradually in later days, his strange disease got relieved months later, and finally recovered. Herbalist Xu made a correct syndrome identification himself, selected exact herbs, and got miracle effects, he knew in depth that the characters of dampness pathogen are sticky and stagnating, not easy to dispel out in a short time, hold on taking the herbs and gradually increase the dosage, then the power of the recipe could be accumulated in the body and finally drove the dampness pathogen out.
