Acne is a chronic inflammatory skin disease of the sebaceous glands of hair follicles, which clinicians call “acne”. “It mainly occurs on the face and manifests as acne, papules, pustules, nodules, cysts, etc., often accompanied by excessive secretion of facial sebaceous glands. “Acne is a serious aesthetic problem, especially in the case of severe nodular cystic acne, which can leave a permanent “pain” in the form of hyperplastic scars on the face. Acne has been known in Chinese medicine for a long time, and has been called “acne”, “pulmonary wind acne”, and “wine acne”. In the Qing Dynasty, Wu Qian and others compiled the book “The Golden Guide to Medical and Surgical Techniques”, saying: “This disease is caused by blood heat in the lung meridian, and every time it occurs on the face and nose, the bumps are broken, shaped like sticky shavings, red and swollen and painful, and white powder juice is broken out. It is advisable to take loquat clear lung drink, external application of upside-down powder, slowly from the work also. Wu Qian discussed the causes of “pox”, the main clinical manifestations and how to treat it. He also proposed a treatment method of taking loquat and lung clearing drink internally and applying upside-down powder externally. Until now, TCM practitioners still use it to treat acne, with satisfactory results. Chinese medicine believes that the pathogenesis of acne is the result of eating spicy and stimulating food or greasy products, which causes heat to accumulate in the lungs and stomach, steaming upward through the meridians, congesting on the chest and face, and accumulating on the skin. In the case of alcoholics, the fumes of alcohol and the wind and cold are the cause of acne. Therefore, the treatment of acne should be based on the pathogenesis of acne and the treatment method should be based on the evidence, mainly on clearing the accumulated heat in the lungs and stomach. This is the reason why Loquat Clear Lung Drink was created. Loquat Clear Lung Drink has the effect of clearing away lung heat. The original formula is composed of six herbs: ginseng, loquat leaf, licorice, Huang Lian, mulberry bark, and cypress. At present, it is mostly improved clinically on its basis to make its therapeutic effect greatly enhanced. Currently, the original formula is mostly composed of removing ginseng and adding scutellaria and gardenia. The formula uses: 10g of loquat leaf, 10g of mulberry bark, 10g of yellow lily, 10g of scutellaria, 10g of cypress, 10g of mountain gardenia, and 6g of raw licorice as the basic formula with addition and subtraction to treat acne with definite efficacy. In this formula, loquat leaf and mulberry bark clear lung heat and lower lung fire, and are the ruling herbs; Scutellaria baicalensis, Huang Lian, and Huang Bai are used together, with Scutellaria baicalensis clearing the lung and mainly clearing upper jiao lung heat; Huang Lian mainly draining heart and stomach fire, and specifically draining middle jiao stomach fire; Huang Bai takes the kidney to reduce heat and remove steam, and mainly draining lower jiao damp heat. Taste sweet raw and slightly cool, and harmonize all medicines detoxification strong. Raw licorice clears heat and detoxifies, and can harmonize all medicines, making it an adjuvant. The whole formula is used together to exert the effect of clearing heat from the lung and stomach. When the heat of the lung and stomach is cleared, the internal organs are cleared and the phlegm and dampness are dispersed, the acne is eliminated and the skin returns to normal. When using this formula to treat acne, we should also add and subtract drugs according to different clinical manifestations and conditions in order to use it flexibly and enhance its efficacy. If the patient has more sebaceous secretion, add Coix Seed and Atractylodes; if itching is obvious, add Bitter Ginseng and White Fresh Peel; if the patient has constipation, add Raw Rhubarb and Aloe Vera; if the nodule cyst is difficult to disappear, add Xia Ku Cao, Trigonella and Curcuma longa; if the patient has dry mouth and lips, add Xuan Shen, Mai Dong and Pollen; if the patient has irregular menstruation, add Angelica, Bai Shao, Yi Mu Cao and Chuan Xiong. Daily skin care is also very important, usually must pay attention to diet and life adjustment, less chocolate, sugar, too sweet fruit, less fatty, fried, fried food and spicy stimulating food; eat more fruit, drink more water, keep the bowels open, life should be regular, to ensure sufficient sleep, keep a happy mood. When cleaning the skin should use warm water, use non-greasy cleanser to wash the face, do not use cool water or hot water with too high temperature, do not use alkaline soap to remove oil, it will lead to excessive secretion of oil, but aggravate the greasy skin. I believe that reasonable treatment and correct daily care methods, “acne” will be less and less, will not “harass” you.
