After the establishment of autumn, it means the arrival of autumn. Autumn is the most beautiful season and the season of harvest. The autumn wind blows, leaves fall one by one, and they float down to the ground one by one, with the unique charm of autumn, rendering the golden color of the earth. The cool and pleasant air, the golden leaves, autumn brings the earth such a charming scenery. However, after autumn, the weather becomes gradually dry due to more sunshine and less rain, especially for people who work outdoors and do not like to drink water, as well as the elderly and children, their bodies will be easily dehydrated, so there will be what people often call “autumn dryness”. According to Chinese medicine, dryness is the main qi of autumn, with the characteristics of dryness and easy to hurt the fluids and damage the lungs. Usually, autumn dryness can be divided into warm dryness and cool dryness: early autumn and late summer with the remaining heat of the evil often form warm dryness; while late autumn and nearly winter combined with the evil of cold is often cool dryness. If the autumn dryness is combined with irregular diet, insufficient rest time, and excessive fatigue, it is easy to make the turbid gas of the stomach and intestines cannot be discharged in time, forming internal heat and injuring fluid, which eventually leads to the occurrence of autumn diseases such as heat constipation. For this kind of autumn dryness caused by constipation, Chinese medicine is how to solve the problem? The wisdom of the ancients is: increase the water to travel the boat. When “increase water rowing boat” belongs to the category of Chinese medicine under the law, meaning: when there is water, the boat can walk smoothly; without water, the boat will stop, at this time, even if you push again, the boat is difficult to travel, if you can make the water full up, and then push the boat will be much easier to walk. Chinese medicine’s “increase the water to move the boat” is precisely the use of this reasoning, designed to “increase the liquid soup” to nourish Yin, moisten dryness, laxative. Therefore, “Zengliang Tang” is also a representative formula of Chinese medicine to increase water flow. It is mainly used for constipation due to “deficiency of fluid, no water stopping” and “heat and fluid dryness”, with 30 grams of Xuan Shen, 24 grams of Mai Dong and 24 grams of Sheng Di. This formula is a combination of three herbs. In the formula, Xuan Shen nourishes Yin and clears heat, which can moisten the bowels; Sheng Di is sweet and bitter, cold in nature, which not only clears heat and nourishes Yin, but also helps Xuan Shen increase the function of nourishing Yin and moistening dryness; Mai Dong is sweet and cold in nature, which can nourish the lung and stomach, moisten the bowels and open the bowels. The combined use of the three medicines can not only treat dry stools, but also a series of symptoms such as itching, dryness and cracking of the skin, dry throat and thirst, dry cough and less phlegm caused by warmth and dryness. Modern medical research has also found that Zengliang Tang is effective in treating mouth ulcers, chronic periodontitis, allergic colitis, anal fissures, hemorrhoids and other diseases. Although TCM’s “liquid-boosting soup” has a variety of effects such as liquid-boosting, anti-inflammatory, antipyretic, and enhancing gastrointestinal peristalsis, it must be used in conjunction with one’s own constitution, and should not be used indiscriminately, such as obesity, phlegm, and spleen deficiency diarrhea, which are often accompanied by loose stools, commonly known as “diarrhea “Because of the cold nature of the liquid-boosting soup, people with spleen deficiency diarrhea will not only be unable to relieve autumn dryness after consumption, but also aggravate diarrhea. Also, cold patients should not take it indiscriminately, because taking tonic products during the period of external sensation will cause the external evil to stay stagnant and not go, that is, the so-called “closed door to stay invasive” in Chinese medicine, so that the external sensation is difficult to heal. Therefore, in the selection of prescriptions and medications to treat autumn dryness, it is necessary to carefully analyze the evidence and not to generalize the whole picture.
