↑↑↑ Click above Beauty Industry Technician Circle, all beauty industry people are paying attentionWhat is Liu Yin (Six Evils)?What does Liu Yin mean? The term “Liu” refers to the six types of weather changes: wind, fire, cold, heat, dampness, and dryness, while “Yin” means excessive. In other words, when these six types of weather changes become excessive, they can invade the human body as external evils, causing harm to our health.
1. Wind Evil Harms the Head and Face1. “Those harmed by wind are first affected above”. Wind evil generally invades the head and face. For example, headaches, runny noses, facial nerve paralysis, allergic rhinitis, and facial muscle spasms caused by colds are generally considered by TCM to be due to wind invasion. Treatment will first consider expelling wind and resolving the exterior. 2. “Wind is good at movement and changes frequently”. TCM believes that diseases that move around and have no fixed location are caused by wind evil. For instance, some pains that shift from left to right, or abdominal pain that alternates with back pain, lead TCM to first consider whether wind evil is the cause, and treatment should first focus on expelling wind and resolving the exterior. 3. “Wind is the leader of all diseases”. Cold and heat evils are difficult to invade the body alone; they often rely on wind evil. Therefore, it is said that “wind is the leader of all diseases”. Key points to differentiate between wind-cold and wind-heat syndromes include cold, pain, and sweating.2. Cold Evil Harms Yang and Causes Cold Pain1. “Cold is a Yin evil that easily harms Yang Qi”. “Yang deficiency leads to external cold, while Yin deficiency leads to internal heat”. These two statements correspond to each other. TCM emphasizes analogy and often relates to natural phenomena, making it easier to understand. 2. “Cold has a stagnating nature”. Unlike wind evil, which is not fixed, cold evil causes stagnation and immobility. Once stagnated, it becomes blocked, leading to pain. Women in postpartum confinement should avoid cold; for instance, if they are exposed to cold on their back during this period, they may frequently experience back pain and discomfort, feeling cold and difficult to treat. 3. “Cold has a constricting nature”. For example, many people like to curl up their legs while sleeping in winter, which illustrates this principle. Therefore, when a person is affected by cold, they do not sweat. One distinction between wind-cold and wind-heat colds is that wind-cold colds do not produce sweat, while wind-heat colds do. 3. Heat Evil Causes Heat Stroke1. “Heat is a Yang evil, characterized by heat”. Heat evil often appears in the hot summer, thus classified as a Yang evil with a hot nature. Common symptoms of heat stroke include flushed face, irritability, strong heat, fever, rapid pulse, and excessive sweating. 2. “Heat has an ascending and dispersing nature”. The characteristic of heat evil is that it easily ascends and disperses outward, particularly harming Qi and body fluids. When a person suffers from heat stroke, Qi is depleted, body fluids are reduced, leading to excessive sweating and little urination, making them prone to fainting. 3. “Heat evil often accompanies dampness”. During heat stroke, dampness often invades the body. This is because summer is not only hot but also rainy and humid, so heat stroke often comes with dampness, leading to symptoms such as fever, thirst, irritability, chest tightness, nausea, vomiting, diarrhea, and fatigue. 4. Damp Evil Causes Heaviness and Fatigue1. “Dampness is heavy and turbid”. After being affected by dampness, one often feels dizzy, heavy, fatigued, with joint pain and weakness. Due to dampness, one feels wrapped up. TCM has a saying: “Draining dampness makes the body light”; detoxification also makes the body light. Which is correct? I believe it must be symptom-specific; if there is dampness in the body, draining dampness will naturally lighten it; if there are toxins, then detoxification will naturally lighten it. 2. “Dampness obstructs Qi and damages Yang Qi”. This means that it is not Yang deficiency itself, but damp evil that blocks Yang Qi. It is like a problem in the heating pipes; no matter how much heat is added in the boiler room, the areas that are blocked remain cold. Where Yang Qi cannot reach, it is cold. When Yang Qi is blocked from reaching the hands, they feel cold; when it cannot reach the feet, they feel cold; when it cannot reach the lower abdomen, men may experience impotence, and women may suffer from cold womb and infertility. Therefore, treating female infertility sometimes cannot rely solely on tonifying the kidneys or invigorating blood; patients with significant dampness must rely on draining dampness and unblocking Yang to see results. 3. “Dampness is sticky and lingering”. Patients with dampness often require a long treatment process, and one must be prepared for a prolonged battle, sometimes needing three months, half a year, or even one to two years to adjust their constitution, as dampness is persistent and sticky. The best approach for a prolonged battle is dietary therapy. 4. Dampness tends to move downward. Damp evil moves downward, in contrast to wind evil, which moves upward. Therefore, many issues in the lower half of the body, such as swelling in the lower limbs, abdominal distension, diarrhea, or sticky and unsatisfactory stools, or difficulty urinating, should first consider dampness. Why does a person have significant dampness in their body? There are several main reasons: a preference for cold foods, a liking for greasy foods, a fondness for smoking and drinking, and indiscriminate use of supplements. Additionally, environmental issues and familial or hereditary factors may also contribute. 5. Dry Evil Causes Dryness and Harms the Lungs1. Dry evil causes dryness and easily harms body fluids. After being harmed by dry evil, one may experience dry mouth and throat, dry eyes, dry nose, thirst, and reduced urination. 2. Dry evil easily harms the lungs. After lung damage, one may experience dry cough, no phlegm, or even coughing up blood. Bai He (Lily Bulb) can moisten the lungs and stop cough, and it also helps combat fatigue. 6. Fire Evil Causes Inflammation and UlcersFire and heat are of the same category; when heat intensifies, it is called fire. 1. “Fire is a Yang evil, characterized by inflammation”. Fire tends to rise; when a person has fire, the eyes, ears, and mouth are prone to problems, which is very common. 2. Fire evil, like dry evil, easily damages the body’s righteous Qi and body fluids. When there is excessive internal fire, bleeding can easily occur; many people experience nosebleeds, heavy menstrual bleeding, or bleeding from other areas, often due to fire evil. Such bleeding cannot be treated solely with hemostatic drugs; bleeding caused by fire must be cleared. Da Huang (Rhubarb) and Huang Lian (Coptis) in the Xie Xin Tang (Drain the Heart Decoction) are used to clear fire specifically for bleeding caused by fire evil. 3. Fire evil easily leads to boils and sores. Boils can occur on various parts of the body due to fire evil, which falls under the category of TCM surgery.Acupuncture Moxibustion to “Expel Evil from the Surface”Urticaria, skin itching, and rashes can be treated with moxibustion at points such as Dazhui (Da Zhui Point) and Mingmen (Mingmen Point) to expel wind evil and relieve itching. Dysmenorrhea can cause extreme pain, leading to a pale complexion. In this case, moxibustion at Guanyuan (Guanyuan Point) can be selected to expel cold evil and promote smooth Qi and blood flow. Heat evil can affect the head, leading to dizziness and vertigo. Moxibustion at Yintang (Yintang Point) can be selected to expel heat evil, effectively alleviating dizziness and vertigo. Abdominal distension and difficulty urinating can be treated with moxibustion at Zhongwan (Zhongwan Point) to expel damp evil, gradually expelling the evil from the surface. For dry and difficult bowel movements, moxibustion at Mingmen (Mingmen Point) can be selected to expel dry evil, effectively improving the symptoms of dry and difficult bowel movements. For tremors in the hands and feet, moxibustion at Hegu (Hegu Point) can be selected to “expel evil from the surface” and cut off the disease.
“Shiji: Bian Que Cang Gong Liezhuan”: “When the spirit cannot stop the evil Qi, the evil Qi accumulates and cannot be released, leading to a slow Yang and rapid Yin, resulting in sudden death.” This shows that when evil Qi invades the body, if it is not dealt with in time, the evil Qi accumulates and cannot be expelled, causing greater harm to the body. In the early stages of evil Qi invasion, performing moxibustion can open a path for the evil Qi to exit, “expelling evil from the surface”, allowing the body to restore its “innate” strength and return to a normal state.
