Moxibustion, according to its fiery nature can warm the meridians, activate blood, dispel dampness and disperse cold, treatment of cold evidence, the natural justice, but for hot evidence can use moxibustion, there have been two views of hot evidence can not be moxibustion and hot evidence can be moxibustion. The former is represented by Zhang Zhongjing, a medical sage of the Han Dynasty, who described the adverse consequences of using moxibustion in hot cases as being more dire, such as “Treatise on Typhoid” 119: “The pulse of the micro count, caution not to moxibustion, because the fire is evil, it is annoying and rebellious, chasing the deficiency and chasing the real, blood scattered in the veins, although the fire is weak, internal attack is powerful, scorching the bones and hurting the tendons, blood is difficult to recover. It is believed that moxibustion should be avoided for the body with Yin deficiency and internal heat, because moxibustion can easily injure the fluid, which can lead to the serious consequences of the depletion of Yin and blood and the formation of scorched bones and injured tendons. The “Treatise on Typhoid” 115 cloud: “pulse floating, heat, and moxibustion, this is the real. The actual to deficiency treatment, because of the fire and move, will be due to dry vomiting blood.” It is believed that the evidence of actual heat should not use moxibustion to supplement Yang, otherwise it will hurt Yin and move fire, forcing blood to move delicately. Zhang Zhongjing’s view had a great influence on later generations and became the mainstream view in modern acupuncture clinics. In the Tang dynasty, Sun Simiao’s “The Essential Formula of the Thousands of Gold” and “The Winged Formula of the Thousands of Gold” not only established some basic principles of moxibustion from the theoretical and clinical points of view, but also expanded the indications of moxibustion to include uncomplicated diseases, acute diseases, and heat. For example, “The Thousand Gold Winged Formula? The first of these is to make sure that the person is not suffering from a disease that is not a disease. The “Prepared Emergency Thousand Gold Essential Formula? The “small intestine is full of heat, moxibustion Yindu, with the year strong”. The first thing you need to do is to get a good idea of what you’re looking for. The “back and back inconvenience, tendon contracture paralysis pain, deficiency of heat and internal cold, moxibustion twenty-two.” These all indicate that heat can be moxibustion. In the Jin Dynasty, Liu Wansu believed that moxibustion has the function of “drawing heat out” and “drawing heat down”, and advocated the use of moxibustion for heat. In the Yuan dynasty, Zhu Danxi perfected the method of “drawing heat out” and “drawing heat down”. In the Yuan Dynasty, Zhu Danxi perfected the theory of “hot evidence can be moxibustion”, considering that hot evidence includes actual heat and deficiency heat, and summarized the function of moxibustion for hot evidence as “drain and draw heat down”, “dispel fire and dispel phlegm”, “nourish Yin and clear heat”. It is also known as the “clearing of heat”, “dispersing fire and dispelling phlegm” and “nourishing Yin and clearing heat”. In the Ming Dynasty, Gong Juzhong pointed out clearly in his “Phlegm Fire Point Snow” that “it is difficult to enumerate the functions of moxibustion to remove disease, where the deficiency of reality, cold and heat, light and heavy, far and near, there is no way to be inappropriate.” The “Moxibustion”, more clarified the mechanism of heat evidence can be moxibustion: “deficiency of heat with moxibustion, yuan qi flow around; real heat with moxibustion, depression heat can be treated; surface heat can be moxibustion, sweating appropriate plan; internal heat can be moxibustion, guidance called superior. Fire depression should be issued, …… the same qi seeking each other, open the door to chase the thief, smooth qi rowing boat.” Yu Tuan’s “Medical Zhengzhuan” and Wang Ji’s “Acupuncture and Moxibustion Question and Answer” explain the hot evidence can be moxibustion: “deficiency moxibustion, so that the fire gas to help the vital energy also; real moxibustion, so that the real evil with the fire gas to disperse also; cold moxibustion, so that its gas to re-warm also; hot moxibustion, leading the evil heat of the gas outside the hair, fire on the meaning of dry also.” The above shows that the ancients were very respectful of the moxibustion method, and the application is very wide. The author believes that Zhang Zhongjing’s saying that hot evidence cannot be moxibustion is mainly for systemic hot evidence, while the later saying that hot evidence can be moxibustion is mainly for localized hot evidence, such as surgical sores and boils, or cold-heat mixed evidence, or cold-heat refusal evidence, or yin-yang both deficiency evidence. In this way, there is not much contradiction between the two views. In general, moxibustion is not used for systemic solid heat or deficiency heat, or at least it should be used only under the premise of using heat-clearing medicine or yin-clearing medicine; for other cases of heat, moxibustion can be used, but we should pay attention to the amount of moxibustion and the method of operation, as well as the use of other methods. The author uses moxibustion extensively in the clinic, for heat, usually with the blood stabbing therapy, especially commonly used to release blood from the ear tip, because the fire is inflammatory, whether actual fire, or false fire, can rise upwards, some symptoms of the upper jiao, head and face, and the ear tip has good effect on such symptoms. In the clinic, I often encounter patients with “upper heat and lower cold”, that is, patients with sores on the mouth and tongue, swelling and pain in the throat, or with irritability, but at the same time have a cold stomach and abdomen, and chills in the lower limbs. Such people take cold medicine to “remove fire”, the stomach cold can not stand, legs and feet more cold; eat warm medicine or spicy food, it is easy to get on fire, so the dilemma is very painful. In this regard, the author often in the lower extremities of the points with moxibustion, received very good results. Because moxibustion can lead the fire downward, to promote the balance of yin and yang to reach.
