Article 247 of the “Treatise on Typhoid” says: “The floating and astringent pulse of the fallen Yang is strong in the stomach, and the astringent is the number of urine, and when the floating and astringent are fighting each other, the stool is hard, and the spleen is about the spleen. In later times, it was mostly explained by “the stomach is strong and the spleen is weak”, “the spleen is deficient in Yin” and “the spleen cannot move its fluids for the stomach”. We think it is not consistent with the original purpose, to understand the original intention of Zhang Zhongjing, should grasp the following points: (l) the location of the disease disease: “typhoid” Article 179 cloud: “sun Yangming, the spleen about is also; positive Yang Yangming line, the stomach home is also real; Shaoyang Yangming, sweating, urine has been, the stomach in dry, annoying, real, difficult stool is also. Sun Yangming refers to the disease in the sun into Yangming, the disease is heavy in Yangming, its nature is real, non-spleen weakness can not be for the stomach to move its fluid; (2) pulse floating pulse astringent: Cheng Wuji said: “fall Yang, the spleen and stomach pulse diagnosis. Floating for Yang, know that the stomach is strong, astringent for Yin, know that the spleen is about”. Combined with the “Jin Kui Essentials” Zhang Zhongjing mentioned “fall Yang pulse floating and astringent” and the pulse evidence of a total of three, one for the spleen about, two for cholera, two for gastric rebellion, the common denominator of the three is that the dampness is obstructed, the qi elevation is not normal, from the clinical point of view, the pulse floating for the dry heat of the lung and stomach, the pulse astringent for the astringent stagnation of qi and blood, because the stomach likes dampness and hate dryness, if the spleen for the stomach heat about, will lead to Dampness and heat fight, qi stagnation, lifting and lowering is not normal, turbidity does not descend then hard stool; fluid partial seepage bladder then urine number. (3) floating and astringent fight: floating main stomach heat, the stomach belongs to the internal organs, is Yang, belongs to the table, like dry, to descend as smooth; astringent main qi and blood astringent stagnation, the spleen belongs to the organs, belongs to the yin, belongs to the inside, the main wet, to rise for use. Floating and astringent fighting is the meaning of stomach heat and spleen dampness fighting each other and causing the Qi to rise and fall out of order. Just as the wind and water fighting each other, floating and astringent fighting each other is said. Article 216: “The pulse is floating and hollow, floating for Yang, hollow for Yin, floating hollow phase combat, stomach heat, its Yang is extinct.” “Floating and astringent phase fight” and “floating and hollow phase fight” both reveal the changes of yin and yang, surface and internal organs pathogenesis from the pulse, which can be seen that Zhang Zhongjing attaches importance to the pulse. (4) stool hard urine number: Article 244: “Sun disease, inch slow, Guan floating, ruler weak, the person has fever and sweating, and vicious cold, not vomiting, but the heart under the plankton, this by the doctor also. If it does not, the patient is not vicious cold and thirsty, this is transferred to Yangming. The number of urine, stool must be hard, not change clothes for ten days, no suffering. Thirsty for water. Less and less with it, but with the method of rescue. For those who are thirsty, Wu Ling San is appropriate.” This article discusses the symptoms of the Sun’s disease that is transformed into Yangming with the symptoms of urine count, hard stools and thirst. The pathogenesis is very different from that of dry heat and Yin deficiency. Throughout the clinic, dry stool and small stool are Yin deficiency; stool pond and small stool are wet; hard stool and small stool are damp-heat. Study the significance of the formula of hemp seed kernel can be seen, hemp seed kernel moisten intestinal dry laxative for the ruler, supplemented by rhubarb to clear heat and dampness, pass the internal organs to lower turbidity, peony and Ying benefit yin, and ease the urgency; adjuvant almond to promote lung Qi, moisten the intestine to lower turbidity, Citrus aurantium to drain heat and remove the real, regulate and smooth the qi flow; make honey for the pill, slow figure its function. In short, it has the function of clearing dampness and heat, clearing the qi flow and regulating the two bowels. Thus, it can be deduced that: hemp seeds and nuts pills to treat the real dispel the evil, not the treatment of deficiency of the formula. Its reasoning is apparently consistent with the damp-heat fight, qi stagnation, lifting and lowering irregularities, dysbiosis. As Yu Jiayan said: “The spleen is weak when it is tonic. Why do you use rhubarb, citrus aurantium and thick park in the formula?” From ancient times to the present day, medical doctors have differed in their opinions about the treatment of spleen. The word “spleen”, in terms of its superficial meaning, is understood by some to mean “the spleen is restrained”; most believe that it means “the spleen is weak and cannot move its fluids for the stomach” and “the stomach is strong and the spleen is weak”, “This statement narrowly understands “spleen contract” as “spleen trapped”, which then evolves into “spleen weak”; Some people think it is “deficiency of spleen yin”; others think it is a solid evidence of spleen and stomach and a light evidence of Yangming. If we think about it, it seems to be inconsistent with the original purpose. If the spleen is weak and cannot transport water and dampness, it will lead to diarrhea and cannot lead to firm stools; if the stomach is dry and yin is injured, it is difficult to pass the number of urine. Clinical evidence of constipation is quite a lot, the etiology of the complex pathogenesis, there are Yangming internal organs real three Cheng Qi of the steep down heat knot; there is the latter intestinal dry Jin withered increase liquid Cheng Qi Tang of the increase of water row boat; there is a weak spleen and stomach stool hard at first after the loose Hovenia pill of the spleen to lower turbidity; there is a lack of kidney essence Jichuan decoction of the kidney to moisten the intestines. In my opinion, Zhang Zhongjing’s theory of “the spleen is about” is different from Yangming’s internal organs, although it is named “Sun Yangming”, the theory of “the spleen is about” is intended to be different from the stomach family, but is actually a variation of Yangming Although the name “Sun Yangming” and the theory of “the spleen is the contract” are intended to distinguish it from the stomach, it is actually a variation of Yangming, i.e., the spleen and stomach are surrounded by dampness and heat, and the spleen is not normal in lifting and lowering, and the fluid is unbalanced in transmission and distribution. Therefore, the small Cheng Qi to clear the damp heat, regulate the Qi and laxative, with the hemp seed kernel of the moist, slow peony, the beauty in the almond of the propagation, worth contemplating, Wu Jutong almonds have “propagation of the lung Qi, lung Qi is open, the dampness of the gas is also transformed” the theory and Zhang Zhongjing original meaning is very consistent. In clinical practice, only a broad understanding of the evidence and treatment of the spleen, not bound to the “stomach strong spleen weak”, ‘”spleen Yin deficiency”, in order to understand the true meaning of Zhang Zhongjing: flexible application, expand the scope of its main treatment.
