Rock sugar. Rock sugar nourishes yin and produces body fluids, moistens the lungs and relieves cough, and has a good auxiliary therapeutic effect on lung dry cough, dry cough without phlegm, and expectoration with blood, so I won't say much. The choice of rock candy tends to be polycrystalline rock candy, which is also called earth rock candy. In fact, polycrystalline rock candy, single crystal rock candy and white sugar are different in earthwork medicine: white sugar is used in pear soup, and the effect is not good; Single-crystal rock sugar is formed by modern machine processing and crystallization on the basis of traditional technology, which seems to be far from the feeling of traditional Chinese medicine. Only polycrystalline rock candy is naturally crystallized by traditional processing, commonly known as natural rock candy, so it is better to prepare drugs for soaking alcohol and nourishing adjuvant.

Pears. According to Chinese medicine, pear is slightly cold and sweet, which can produce fluid to quench thirst, moisten dryness and resolve phlegm. It is mainly used for diseases such as fever, body fluid injury, vexation and thirst, lung dryness and dry cough. Pear also has the effects of clearing away heat and calming nerves, and has a good auxiliary effect on patients with hypertension, heart disease, insomnia and dreaminess. At the same time, it is also a health care fruit for patients with hepatitis and kidney disease in autumn. Pear is a good fruit, but it should not be eaten too much. Too much will hurt the spleen and stomach and help damp, so people with spleen deficiency and loose stool should eat carefully. After verification, the most suitable materials are Yali pear and Sydney, and fragrant pear is also acceptable.

Pear can moisten lung and clear away heat, promote fluid production and quench thirst. It can be used together with rock sugar to enhance the effect of moistening and relieving cough, and can be used to treat children's lung dry cough, dry cough without phlegm, dry lips and dry throat. Sydney can nourish yin and moisten the lungs, nourish the stomach and produce fluid, eliminate phlegm and relieve cough, which has a good maintenance effect on the throat; Moreover, there are many sugars and vitamins in pears, which are easily absorbed by the human body.
