The use of cold and hot medicines together is called the concurrent use of cold and heat. And the use of cold and hot drugs, in the formula can be the same as the king of the drug, the same as the subject of the drug, the same as the adjuvant; or a for the king and a for the subject, a for the king and a for the adjuvant, a for the king and a for the use of a very wide range of cold drugs and hot drugs, there is a complementary, make, and make the system into the role of each other. 1, cold and heat together when the cold and heat, together for the king, together for the subject drug, or a for the king and a for the subject drug, there are often cold and heat together with the wonderful. For example, the Bureau of “black tin Dan,” the cold black tin with sweet Yin, suppression of floating Yang, lowering the reversal of asthma; and the acidic heat of the sulfur Huang Jun tonic fire, cold warm kidney, two drugs a cold and a hot, a yin and a yang, and do the same as the king’s medicine, there is a fire and water and tonic, and must be the wonderful. Another example is Huang Tu Tang of Jin Gui, because the bleeding mechanism of this disease has two aspects: spleen qi deficiency and cold, not being able to control blood and liver heat not being able to hide blood, and the former is the main one, therefore, it is used with Radix et Rhizoma Atractylodis Macrocephala, Radix et Rhizoma Atractylodis Macrocephala, Colla Corii Asini, and Radix Scutellariae Radix et Rhizoma Atractylodis Macrocephala, which is used to replenish the spleen yang and benefit the spleen qi to regain the right of blood control of the spleen, and Radix et Rhizoma Asini and Colla Corii Asini to clear the liver and nourish blood, in order to regulate the function of the liver for the collection of blood. The use of the hot and pungent Radix et Rhizoma Polygonati Odorati with the sweet and cold Radix et Rhizoma Polygonati is the same as the ministerial drug, so that warming the yang and strengthening the spleen does not harm the yin, and clearing the liver and nourishing the blood does not hinder the yang. Han’s medical pills “Jiaotai pill with Huanglian, cinnamon formula, the treatment of insomnia of the heart and kidney; the ancient formula Jianglian San with ginger with Huanglian treatment of dysentery, the two sides are a gentleman, a subject, cold and heat mutual aid example. “are a cold and a hot, a yin and a yang, cold because of heat with, hot because of cold with, yin and yang, the most wonderful system of the formula, so there is a success without prejudice to the harm also.” 2, cold and heat make Li Shizhen said, “phase makes, I’m also making.” When cold and heat are used together, one for the king and one for Zuo (ZuoSu or ZuoShi), or one for the king, one for the medicine, cold and hot drugs are often each other for ZuoShu and have synergistic effect. Such as the “Jin Gui” warm meridian soup, with hot and pungent Wu Yu with Gui Zhi for the monarch, in order to warm the meridian line stasis, in addition to the use of ginseng in addition to the blood, but also with bitter cold peony dandelion and sweet cold maitake with the Colla Corii Asini, nourishing yin and nourishing the blood, moistening the pulse channel in order to increase the water to line the stasis of blood from the Chong Ren veins in the next line, similar to the later generations of the treatment of yangming heat knot yin deficiency to increase the water to line the boat law, Wu Yu with maitake and dandelion, the cold and heat of the nature of the opposite, a monarch, one for the adjuvant, between cold and hot drugs, but also a synergy of the two. The effect of the cold and heat medicines is synergistic. For the heavy cold and heat evidence of the evil, casting hot or cold medicine, if the disease drug resistance, the disease does not accept the drug and the occurrence of the refusal of the grid, often used in conjunction with the disease gas from the cold or hot medicine, cold and hot and used to eliminate the refusal of the grid, is the cold and hot counter-support. For example, Tong Wei Si Reverse plus Pig’s Bile Soup and Bai Tong plus Pig’s Bile Soup, the bitter cold pig’s bile can lead the great Xin Da Hao’s appendicitis and dry ginger into the yin, in order to eliminate the yin to the full bloom of the pungent and hot medicine of the refusal to accept, with the counter-supporting effect. Tongguan Pills respectively take Huangbai and Zhimu as the principal and ministerial medicines to clear heat, dry dampness and firm up the yin, and use less pungent and hot cinnamon as the adjuvant medicine, which can not only induce Zhimu to enter the lower jiao kidneys and bladder and blood, but also pass the yang qi and help the qi, and adjuvant the principal and ministerial medicines to pass the urine, and support the transformation of dampness and heat. Both the king and the minister are cold medicines, and use a hot medicine cinnamon, both as a supporting and citing the two positions, cold medicine and hot medicine, although different, and can have a cold and hot synergistic use of each other. 3, the system into each other cold and heat, both cold and heat, but also heat and cold, used to restrict the toxicity of the main drug, potent or treatment of unwanted drug activity, can enhance the strengths and weaknesses, to avoid harm, this cold and heat and into the role of each other, can be divided into cold and heat and cold and hot with the system and cold and hot concoctions of the system of the two categories: ① cold and heat with the system of the system of the system of cold and hot medicines, a king, one as the system of the system of the system of the system of the system of the system of the king of the system of the system of the system of the system of the system of cold and hot medicines, a king, a king of the system of the system of the system of the system of the system of the system of the role. Such as the “Jin Gui” three things to prepare for the emergency pill, with bitter cold rhubarb for the adjuvant, adjuvant big Xin big heat of the king’s medicine Batou and the subject of medicine ginger, can reduce the toxicity and potency of Batou, and can be pushed to the new. The use of heat as an adjuvant to cold, such as Paeonia lactiflora Tang, can restrain the coldness of the pungent and hot drug Cinnamomum cinnamomi in the team of cold drugs such as Scutellaria baicalensis, Rhizoma Coptidis and Rhizoma Dahuang, preventing the bitter cold from injuring the middle and iced over the evils of dampness and heat, and it can also support and neutralize dampness and heat. With Paeonia lactiflora, there is a strengthening of the function of blood circulation and dysentery, a drug and both the dual role of adjuvant and adjuvant. The same as the adjuvant, in the formula can also be cold and heat, used to antagonize the treatment of unwanted drug activity. Such as Suhexiang Pills in the rhinoceros horn and Wicker as adjuvant, with rhinoceros horn is to use its detoxification function, but rhinoceros horn cold, impede the opening of cold closure of the junshen medicine, so the adjuvant use of pungent and hot Wicker to antagonize the cold and enhance the formula Suhexiang and other 10 aromatic junshen medicines, cold and pain relief, the pungent open the role of the depression. In this way, take the rhinoceros horn detoxification function and avoid its coldness, sex with each other, can Platypus incredibile spoiled tic poor suffocation umbrella ② hot and cold concoction adjuvant: the hot and cold nature of the opposite drugs together concoctions, and then only the main drug into the drug, can change its performance. Such as the Tiantai Wu Yao scattered neem and bazhou with fried, and then go to the bazhou and only use neem, can reduce the coldness of neem, but also to enhance the function of the gas dispersal. Another example is the Huanglian of Xianglian Pill, which should be fried with Cornu Cervi Pantotrichum, and then only Neem Zi is used to reduce the coldness of Huanglian, and the pungent flavor of Cornu Cervi Pantotrichum can be used to disperse dampness and moisten dryness, so as to treat dampness-heat diarrhea, dysentery, and thirst.
