I often use the six sutras of typhoid fever, and often several sutras are used together, or one sutra is the main and other sutras are taken into account. This involves the problem of interrelationship between the six meridians. Typhoid scholars have said that the six meridians are transmitted in a clear order, but I think this is also for the convenience of reasoning. Mr. Zheng Qin’an’s “Medical Method Roundup – One Qi for All Diseases” says: “There are ten thousand diseases, which originate from one element. One element, two qi muddled into one qi also. One qi is surplus and contraction, the disease is born. There is a surplus that is fire, not enough that is cold. …… six qi cycle, each order of organs can be based on; six qi that is six sutra, six sutra is still a sutra; five elements into five qi, five qi is still a qi. The sun is unveiled to speak of the beginning of the gas, the theory of the Turk’s Yin to speak of the end of the gas, the cycle of day and night, the cycle of the week, the disease also, sick this gas also. The Qi industry is the great use of the surrounding body shell. The use of medicine to cure disease, the actual treatment of qi also.” The five elements of yin and yang are for the convenience of reasoning, and are born from the same qi, and have different names. The Yellow Emperor’s Classic of Internal Medicine – Suwen Yin and Yang on the separation of the two elements says: “The sun is the opening, Yangming is the closing, Shaoyang is the pivot. Taiyin is the open, Conjunctive Yin is the close, Shaoyin is the pivot”, which is later called “open and close pivot”, a convenient way to understand the operation of the six meridians in the human body. Let’s look at the “correspondence between heaven and man” as an axiom, without discussing it, and correspond the signs of the four seasons to the luck of the six meridians, which can help us better understand the “one qi for all diseases”, the “six meridians of typhoid fever The essence of “typhoid fever and six meridians” and the operation of “open and close pivot” of internal meridians. This process is the combination of sympathetic yin, as the sunlight of heaven and earth begins to rise, and grass and trees begin to grow, as the sutra says: “In March of spring, this is the beginning of development, heaven and earth are born, and all things are glorious”; Taiyin wet earth should be in summer, the opening of Taiyin, with the warmth of fire, things are transformed, as the sunlight of heaven and earth shines, and grass and trees flourish, as the sutra says: “In March of summer, this is the beginning of development, as heaven and earth are shining, and grass and trees flourish. The sutra says: “In the summer of March, this is called the summer show, the sky and earth, everything is flamboyant”; Yang Ming dry gold should be autumn, Yang Ming’s combination, Sheng Yang within the collection, all things return to their roots, such as heaven and earth autumn breeze send cool, grass and trees begin to wither, the sutra says: “In the autumn of March, this is called Rong Ping, the weather to be urgent, the earth to be clear”; Sun cold water should be winter, the weather to be urgent, the earth to be clear. The sun’s cold water should be winter, the sun’s opening, the cloth Yang into the ground, the essence of the Tibetan, such as the world’s ice and snow, grass and trees grow, the sutra: “March, this is closed, water ice and chap, without disturbing the Yang. Shaoyang phase fire for the winter and spring of the pivot, yin into Yang long, Yang Qi to grow, such as the pivot is out of tune, the phase fire delusion, so Shaoyang pivot Yang; Shaoyin gentleman fire for the summer and autumn of the pivot, Yang kill Yin hide, Yang Qi to hide, such as the pivot is out of tune, Yang deficiency cold, so Shaoyin pivot Yin; the reality is that the gentleman phase fire, different names and the same thing, Yang gathered for the gentleman, Yang scattered for the phase, Yang gathered for Yin, Yin scattered for Yang. Typhoid fever, each with its own formula, the sun, such as ephedra soup, open the sun to cloth Yang; Yangming such as Baihu Tang, combined with Yangming to collect Yang; Shaoyang such as Xiao Chaihu Tang, pivot Shaoyang to pass Yang; Taiyin such as Rizhong Tang, open Taiyin to Yang; Shaoyin such as four reverse soup, pivot Shaoyin to transport Yang; Conjunctive Yin such as Gui Zhi Tang, combined with Conjunctive Yin to ascend Yang. This is only a list of a few prescriptions, if you are interested, refer to the corresponding formula evidence, qi-chemical operation, can be similar to the typhoid fever prescriptions.
