Mulberry leaf, the same source of medicine and tea, “Shennong Ben Cao Jing” classified as “middle class”, said it: “smell bitter sweet cold, has a small poison, the main cold and heat sweating.” About its attribution to the meridian of the various books vary, mostly for the hand Taiyin meridian, hand and foot Yangming meridian. For its efficacy, “this herb seeking truth” said: “clear the lungs and stomach, cool the blood and dry dampness, remove the wind and brighten the eyes, “Sheng Ji Lu” for the treatment of vomiting blood more than, evening mulberry leaves roasted research, cold tea serving three money, only one service stop, after the liver and lung medicine.” The “get with the materia medica” said it: “clear the dryness of the West, diarrhea of the East of the real.” Among the five elements, the east is liver wood and the west is lung gold, so it is clear that it has the effect of clearing lung and moistening dryness, clearing liver and dipping fire. The New Compilation of Chinese Medicine summarizes its efficacy as: “It has the function of dispersing wind and clearing heat, clearing lung and moistening dryness, cooling blood and brightening eyes.” It can be seen that mulberry leaf can clear wind and heat, clear lung and moisten dryness, cool the blood and stop bleeding, dispel wind and brighten the eyes, clear the liver and diarrhea fire, and is used to treat wind-heat external sensation, lung-heat and dry cough, hemoptysis and vomiting of blood. The ancient formulas of Mulberry Chrysanthemum Drink and Mulberry Apricot Soup are representative formulas of mulberry leaves. Mulberry-Chrysanthemum Drink is a famous formula for treating external wind-heat, with mulberry leaves and chrysanthemum as the ruler, which has the effect of clearing wind and heat, promoting lung-heat and relieving cough, and is used to treat external wind-heat offending the lung and causing cough. Mulberry leaf in the formula not only has the power to remove wind and heat, but also can clear the lung and moisten dryness to stop coughing, which is indispensable! In modern times, it is used to treat upper respiratory tract infections, acute tracheobronchitis, etc. Mulberry Apricot Soup is derived from the “Warming Diseases Article”, with mulberry leaves, almonds, zhebeimu, sage, gardenia peel, tempeh and pear skin, which can clear the lung and moisten dryness, moisten the lung and stop cough. Mulberry leaf is the ruling herb, which can remove wind and heat externally, moisten the lung and stop cough internally, and then complemented by nourishing yin and clearing heat, removing wind and heat to help its effect of moistening dryness and stopping cough. In modern times, it is used to treat upper respiratory tract infections, bronchial dilatation and other evidence of dry lung and cough. Modern medicine has conducted more detailed research on the main components and pharmacological effects of mulberry leaf, in its main components, water accounts for 75% and dry matter accounts for 25%. The material basis of its pharmacological action mainly includes flavonoids (rutin and isoquercitrin in high proportion), polysaccharides (mulberry leaf polysaccharides), lipids (high content of unsaturated fatty acids), alkaloids, volatile oil, chlorogenic acid and phytosterols, etc.. Research has found that its pharmacological effects are extensive, including antibacterial and antiviral, cough suppression, lowering “three highs”, anti-aging, anti-tumor, etc. 1.Lowering “three highs” Lowering “three highs” means lowering blood pressure, lowering blood lipids and lowering blood sugar, which can explain why mulberry leaves can be called a medicine and tea of the same origin. Quercetin and rutinoside in mulberry leaves can expand the coronary arteries and improve the heart before and after load, lowering blood pressure. The phytosterols and flavonoids contained in mulberry leaves can inhibit the absorption of cholesterol in the intestinal tract, thus lowering the blood lipid content, and in the process of their action, improve the blood viscosity and cardiovascular lipid deposition, thus improving hyperlipidemia and its series of complications. It is written in the Materia Medica: “It is used as a substitute for tea to quench thirst.” Modern research has confirmed that the present-day diabetes corresponds to the ancient thirst, and mulberry leaves have long been recorded in ancient times as a substitute for tea to stop thirst. Modern research has confirmed that mulberry leaf has obvious effect on lowering blood sugar, and its mechanism of action is to inhibit the absorption of sugar in the intestinal tract and stimulate insulin secretion to increase the use of sugar substances, thus stabilizing blood sugar and achieving the purpose of lowering sugar. 2, anti-inflammatory, antibacterial and cough suppressant Mulberry leaf aqueous extract has good antibacterial effect on both Gram-positive and negative bacteria; and its extract has certain anti-inflammatory effect, which can effectively reduce inflammatory edema and exudation, especially the inflammatory edema of respiratory system and digestive system; and its extract is found to have certain cough suppressant effect, but the specific mechanism and pharmacological basis are not yet known. Its anti-inflammatory, antibacterial and cough suppressant effects are compatible with its effect of removing wind and heat, moistening the lung and relieving cough. 3, anti-aging Quercetin and phenolic substances in mulberry leaves have significant anti-oxidant free radical and superoxide anion effects, and can also reduce the accumulation of lipofuscin, playing an anti-aging role. 4, other mulberry leaves also have anti-tumor, promote ulcer healing, anti-filariasis and so on a variety of effects, here is not detailed. Mulberry leaves have so many advantages, so what people are suitable for taking mulberry leaves? In what way is it best to take it?

In addition to the above three groups of people, others can take it in the appropriate amount with climate change and their own physical condition. Mulberry leaf is the same source of medicine and tea, usually you can drink it as a substitute for tea, so it is convenient and safe. 1.Finished mulberry leaf tea With the continuous development of the economy and health care industry, there are now a variety of mulberry leaf tea health products, whose ingredients are mostly based on mulberry leaf alone, with some products containing other types of substances.
