The color is the external glory of the internal organs, the five organs should be in the five colors, under normal circumstances contain but not reveal. If the five colors are exposed, whether in the face or in the sweat, urine, belt, etc. are all signs of malfunction of the internal organs, the essence can not be taken in, resulting in the overflow of essence. The color sweat can reflect the internal organs of some diseases. 1, the black sweat color black belongs to the kidneys, sweat see black most of the signs of kidney deficiency, such as black and thin is the heart and kidney disorders, when adjusting the heart and kidney to converge essence, such as black and sticky is the kidney yin deficiency damp heat, and when yin clear damp heat. The patient had black sweat on the head and five hearts due to alcoholism, the sweat was sticky and thick with dizziness and dreams, heart trouble, red tongue with thin yellow coating and thin pulse. I imitated the method of clearing damp-heat by transporting the heart and kidneys, and gave Jiaotai Pill combined with Liu Wei Di Huang Tang plus Che Qian Zi, Slippery Rock, Mouton, stacked into more than ten doses and healed. 2, yellow sweat Yellow sweat is a sign of dampness and heat. The yellow color belongs to the spleen, yellow sweat for the spleen color out of the sign, mostly for the spleen is caught by damp heat or spleen deficiency loss of astringency, such as the color is thin and yellow for the spleen deficiency yellow sweat, while the color is sticky and yellow is damp heat yellow sweat. The Golden Horoscope is the record of yellow sweat, such as: “inch mouth pulse sinking and weak, sinking that is the main bone, weak that is the main tendon, sinking that is the kidney, weak that is the liver, sweat in and out of the water, such as water sad, yellow sweat out of the calendar, so called the calendar.” The yellow sweat of the calendar section is mostly accompanied by a loss of spleen transportation and transformation, so the yellow sweat disease is mostly accompanied by swelling, and the differentiation with jaundice is that the eyes are not yellow. The patient consulted Yu because of yellow sweating in the five heart areas (i.e., the heart of the hands, feet, and forehead). He reported that he had pain around his body after plowing in the rain, and then he had yellow sweat gradually. I first gave six doses of mushroom Chen artemisia soup, yellow sweat see light, but the limbs still pain, so easy to Jin Kui Mu Fangji Tang eight doses of healing. 3, white sweat White belongs to the lung, for the lung color exposed, mostly for the heart and lung Yang deficiency, due to the lack of Qi. The white sweat is an ominous sign, such as “Su Wen – Jing Yin Bu Lun” said: “True deficiency of the heart, the sympathetic gas stays thin, the hair is white sweat” means that the white sweat can be seen in the true heart pain, explain the relationship between white sweat and heart and lung deficiency. White sweat is sometimes also occasionally seen in severe pain, for example, the chapter on cold hernia with abdominal fullness in the Golden Horoscope says: “If the cold hernia is painful around the umbilicus, if the hair is white sweat, the hands and feet are cold, and the pulse is sunken and tight, Da Wu Tou Decoction is the main remedy”. 4, red sweat refers to epistaxis, red belongs to the heart, the heart is the main blood vessel, the heart is a fire organ, when the heart fire is heavy, epistaxis can be cured by itself. Red sweat is light red sweat, which is called “blood sweat” in “Treatise on the Origin of Diseases – Blood Diseases”, and is mostly a sign of Qi deficiency, and also a sign of fire in the heart and liver. In addition, there should be a difference between red sweat and epistaxis, which appears in acute fever and high fever and fire, because it plays the role of sweating and heat relief, so it is called “red sweat”, but although epistaxis is also commonly called “red sweat”, the part is not from the Xuanfu, but from the nostrils, so it is not really red sweat. The former sages believe that children born sweating like blood is an inauspicious omen, and many die young. The predictive value of blood sweating is often a signal of bleeding in other parts of the internal body, and the discovery of red sweat requires further examination of the internal body. In addition, taking chemical agents such as potassium iodide, also prone to drug-related red sweat. 5, green sweat for the clear green sweat, clear green for the liver and gallbladder color, green sweat, suggesting the liver and gallbladder essence leakage, clinically seen in the “gallbladder down” a disease (gallbladder by 牋 fracture), is a very bad sign. In addition, the appearance of lime green sweat in the severe stage of thirst disease is a sign of ketosis. In addition, the injection of methylene blue, can also form drug blue sweat.
