The Su Wen? The theory of “yang plus yin is called sweat”, which states that the function of yang qi (including the function of gasification and movement) is the main factor in the formation of fluid memory and outward sweat, that is, yang qi in the body pushes fluid out of the body, which is called sweat. Yin and yang are interdependent and mutually useful, with yang rooted in yin and yin rooted in yang; yang transforms qi and yin forms. The formation of sweat is the result of changes in the functions of both yin and yang, and fluid is the basic substance of sweat, but the formation of fluid is produced by the qi-transforming function of yang qi. The sweating of pathological sweating, such as night sweats, is also the result of Yang Qi and fluid together with the discharge, often seen in the clinical sweat does not solve, “sweating dead Yang also dead Yin”. Therefore, you cannot simply mechanically consider spontaneous sweating as qi deficiency and night sweating as yin deficiency. If any aspect of qi, blood, yin or yang is out of order, or is disturbed by external evil such as dampness and heat, abnormal sweating will occur. In the process of copying prescriptions from the famous Chinese doctor Peng Peichu, I had the privilege of seeing an American male patient who had been treated for 20 years for night sweats. The patient started to sweat at night when he was 20 years old, sometimes lightly, sometimes heavily, and in severe cases, he sweated profusely and his clothes were wet. He is afraid of heat and not afraid of cold, and sweats slightly less when covered with a thin blanket. He was thirsty and drank a lot, with tinnitus, red tongue, thin coating and thin string pulse. The first consultation gave Astragalus membranaceus 15, Atractylodes macrocephala 15, Radix Bupleuri 9, Radix Paeoniae Alba 15, Pericarpium Citri Reticulatae 9, Tortoise Board 12, Phellodendron Bark 9, Fructus Schisandrae 6, Ephedra Root 15, Rhizoma Glutinosa Root 15, Dried Peach 15*14 patches; follow-up consultation: night sweats were significantly less, the front added: Roasted Licorice 6, Cinnamomum Bark 6, Jujube 7*14 patches; only one night sweat in half a month, sweating less; Astragalus membranaceus 15, Atractylodes macrocephala 15, Radix Bupleuri 9, Radix Paeoniae Alba 12. Chen Pi 9, roasted licorice 6, ephedra root 15, tortoise board 12, cypress root 9, Radix Codonopsis pilosulae 15, pulsatilla 12, schisandrae 6, *14 patches. Night sweats for 20 years, severe sweating, wet clothes, Yin deficiency is Yang Sheng, deficiency of heat, Yin Qi is empty, sleep then Wei Qi take advantage of the deficiency into the Yin, the table is not protected, the muscle surface is not dense, the fire in the glory alone in the outside, steam heat, forcing the fluid to leak outside the sweat. Wake up, then the gas is solid in the table, the xuanfu closed and sweating stopped. The use of yu ping feng san to benefit the guard to consolidate the table, raw pulse san to benefit the qi and nourish yin, plus the usual astringent sweat drugs, to achieve good results, re-examination, plus the use of cinnamon, licorice and jujube, and harmonize the Ying and Wei, the first diagnosis less sweat, the second diagnosis to heal, the third diagnosis sweat stopped. Night sweats, which is called “bed sweats” in the Nei Jing, refers to the situation where a person sweats after going to sleep but stops sweating after waking up. The “Ming Medical Guide? The “sweating from the heart sweat” cloud: “night sweat, sleep out, sleep and collect, such as the ko robbers, so to name it”. The majority of physicians believe that the cause of the disease is yin deficiency, for example, such as: “Medical Zhengzhuan? Sweating evidence: “night sweating, sleep and through the body like a bath, and the awareness of the party to know, is a Yin deficiency, the camp blood is also the main. The most important thing is to make up for the Yang and regulate the Wei, and to make up for the Yin and lower the fire.” However, clinically many patients nourish yin and lower the fire is ineffective. The patient is not simply suffering from yin deficiency and fire, but from deficiency of both qi and yin, lack of solidity outside the guard, and disharmony between the camp and the guard. The kidney is the master of the five fluids, which enter the heart as sweat. Inadequate intercourse, overwork, loss of blood and essence, or long term illness, injury to yin, deficiency of yin in the body, deficiency of kidney fluids, internal deficiency of fire, external leakage of fluids, hot flushes and night sweats, false sleeplessness, dizziness and tinnitus, red tongue with little coating, thin pulse, etc. It is good to use Yu Ping Feng San, Sheng Wei San and Gui Zhi Tang, which benefit Wei and consolidate the surface, nourish Yin and astringent sweat, and harmonize Ying and Wei. Therefore, the appearance of sweat, whether physiological or pathological, is the result of Yang transforming Qi, Yin forming, and fluid being changed by Qi and taking juice. The relative dynamic balance between yin and yang maintains the normal physiological function of fluid in the body. When the balance between yin and yang is out of balance, the discharge of fluids will be abnormal, resulting in spontaneous sweating, night sweating, war sweating, etc. In clinical treatment, we cannot stick to the “yin deficiency” theory, and do not know how to adapt.
