TCM treatment of cough should be divided into different types. Different syndromes have different treatment methods. When coughing, boiling pear water is really suitable. It should be two. One is the wind dry cough inside the cough caused by external factors. The recipe used in TCM treatment of wind dry cough is called Sangxing Tang. One medicine in Sangxing Tang is to boil the peeled pear skin with the medicine to treat the wind dry cough. The wind dry cough usually occurs after the cold in autumn. The inside of the lung is quite dry, and when the body fluid in the lung is injured, the pear in the medicine itself is part of the prescription. Pears can also be used when coughing due to yin deficiency. Pears are fresh when they have the best nutrition. Because there were no conditions before, pears were very difficult to preserve. That is, once they were cut, they would change color quickly. When the pulp was white, the nutritional value was the highest. At that time, the content of vitamins, pectin and juice was very high. Once the fruit is rotten, the vitamins will be greatly weakened, and other nutrients will start to decline. So if fresh pears can be squeezed or eaten directly, it is best to eat them directly to absorb the nutritional value. But sometimes, depending on the patient's taste, or some pears are very deep, and too sour pears are not suitable for cough treatment. At that time, you can boil them, and then the sour taste will disappear after they are boiled into water. In this way, it is very good to eat the cooked pears together with the pear soup. Sometimes we may use some rock sugar at home, and try not to add it. Because it is too sweet after adding sugar, this too sweet taste is not good for relieving cough, so a light pear soup is very good.
