Danggui Sini Decoction is from Treatise on Febrile Diseases, which was a famous prescription created by Zhang Zhongjing in the Eastern Han Dynasty. The original prescription was composed of Danggui Sanliang, Guizhi Sanliang (peeled), Paeonia lactiflora Sanliang, Asarum Sanliang, Glycyrrhiza uralensis Erlang (roasted), Tongcao Erliang and Jujube Twenty-five (broken, twelve in one method). A row of Wujiafeng was planted next to the house, with long spiny branches and dense. I don't know how many years ago it disappeared, because people often dig it. Take it to decoction, which can dispel wind and remove dampness, and cure arthralgia. However, because the smell of the branch shell is still relatively heavy, people can only take its white pith, which is colorless and tasteless, and can also achieve the purpose of dredging meridians. It can be used to stew pig's feet and promote lactation for parturient. When I was very young, the old people told me that this white pith was called Tongcao. After practicing medicine, the real cure of the disease with Tetrapanacis quinquefolius is to use this color to enter the lungs, light to ventilate, light to urinate, and because of its weak strength, it is an important task, and it is used as a guide among many drugs. The nature and taste of "Tongcao" contained in the book have always been entangled with "Akebia". There is no "Caulis Akebiae" in Shennong's Classic of Materia Medica, but "Caulis Akebiae". The classics are pungent, flat, non-toxic, removing cold and heat in the spleen and stomach, and dredging nine orifices, blood vessels and joints, which is unforgettable and eliminates evil insects. However, "A Bielu of Famous Doctors" says: sweet, and "Wupu Materia Medica" says: bitter. In Compendium of Materia Medica, Li Shizhen shifted the odor and function of the previous Akebia tetrapanacis to Akebia tetrapanacis, and added another item "Tongtuomu" in the book, saying: "There are fine holes, and both ends are connected, so it is named Akebia tetrapanacis, which is called Akebia tetrapanacis today. Today's grass is the ancient wood. " At this point, whenever the ancient side used "Tongcao", it had to use "Akebia". The injustice of the grass, after Li's book, became an ironclad case. Among the ancient prescriptions, the use of "Tongcao" was first seen in "Danggui Sini Decoction", which was recorded in Treatise on Febrile Diseases by Zhang Zhongjing: Danggui Sanliang, Guizhi Sanliang (peeled), Asarum Sanliang, Glycyrrhiza uralensis Erliang (roasted), Tongcao Erliang, Paeonia lactiflora Sanliang, and 25 jujubes (broken). There are 351 articles in Treatise on Febrile Diseases: "Danggui Sini Decoction is the main treatment for those whose hands and feet are cold and their pulse is thin." In plain English, Danggui Sini Decoction is used when the hands and feet are cold and the pulse is too thin to touch. Qi and blood can't warm the limbs, so it is cold; Qi and blood can't fill the pulse, so the pulse is thin. In Treatise on Febrile Diseases, there is another place where Danggui Sini Decoction is used, and it is recorded in "No Next Part": "Those who benefit from the pulse are weak, so they are strong. It is Danggui Sini Decoction to set the pulse to float, because the intestines sound. " To put it bluntly, it is diarrhea, and the pulse is wide. This is not diarrhea caused by evil, but deficiency. The reason is that Ba Man used laxatives. If the six veins are floating and the bowel sounds still appear, it belongs to Danggui Sini Decoction. The pulse floating in the interior is weak, while the pulse floating in the interior is leathery, while the pulse floating in the interior is weak and cold in the exterior, and the water gurgles between the intestines. In this case, it is necessary to immediately warm up the qi and blood to ward off the external cold, and at the same time, it is beneficial to urinate to ventilate the yang, so as to turn the situation around and avoid diarrhea. Cheng Wuji's Annotations on Treatise on Febrile Diseases explains "Danggui Sini Decoction" in this way: "Neijing says: The pulse is the house of blood. All blood belongs to the heart. Those who pass through the pulse must first replenish the heart and blood. Suffering first enters the heart, and the suffering of Angelica sinensis helps the hard work; The heart is bitter and slow, and it is urgent to eat acid to collect it, and the acid of peony is to collect the heart; The liver is bitter and anxious, and the urgency of eating is sweet, and the sweetness of jujube, licorice and medulla tetrapanacis is slow. " Cheng Wuji clearly pointed out "the sweetness of the grass". Of course, sweetness means sweetness, just like we often say "sweet spring" and "sweet dew". Xu Hong's Annotations on Treatise on Febrile Diseases is more direct: "Angelica is the king to replenish blood; Taking Paeonia lactiflora as the minister, supplemented by nourishing the qi; Taking cassia twig and asarum as pungent ingredients, and dispelling cold and warming qi as auxiliary ingredients; Taking the sweetness of jujube and licorice as the guide, we can benefit from it and make up for its deficiency; With the lightness of the grass, it passes through its veins and sputum. " Clearing yang is not good for urination, and diarrhea is not good for small side, which is not the cure. It can be seen that the medulla tetrapanacis in Danggui Sini Decoction is clearly the bland medulla tetrapanacis that we are used to, rather than the "Akebia" with extremely bitter taste. There is a record about Akebia Akebia in Cuncunzhai Medical Notes, which I reposted below: The Essays of Chongqing Hall states that Akebia Akebia is bitter in taste, so the heart-purging fire comes from the small intestine, and all the herbs are sweet and light, or the words are slightly pungent. Have you not only tasted it, but also inquired about it? Press: The ancient name of Mutong is Tongcao, and now it is Tongcao, and the ancient name is Tongtuomu. Is yunmutong sweet and light, or is it a misinformation of Tongcao? Unknown. In fact, the taste of Akebia manshuriensis is extremely bitter and bad. The world called Huanglian a bitter medicine, but I don't know that the taste of Huanglian is bitter and clear, and the taste of Akebia manshuriensis is bitter and turbid. Ye's medical case used aloe vera as a decoction, and Xu criticized, "Please taste it yourself, and you will know its suffering." I am willing to move the wooden bridge with Sri Lankan. And the wood communication is extremely fast and profitable, so it is not suitable for multi-use. Yu You, Shen Xingtian, said that he once saw a child who took the heavy agent Akebia Mutton decoction by mistake, so he couldn't help urinating, followed by a white paste, such as fine, and he died of crying bitterly. After his death, his urine was broken and there were still several sperm beads. Those who use wood are cautious. A few years ago, due to the "Akebia manshuriensis" incident, the state banned this kind of drugs related to "Akebia manshuriensis", and most of them are currently used in the market. I don't write these things to say that Akebia Akebia can't be used, but I hope that everyone should fully understand them when using drugs. There are wild people in the Jianghu who use loofah vines and pumpkin vines instead of Akebia stem. Although they are helpless, they are enlightened people after all.
