Loquat can be used to some extent to relieve cough, mainly for coughing caused by lung heat, and is usually taken in the form of a decoction. Pei Pa Koa is the fruit of Pei Pa Koa, family Rosaceae. According to Chinese medicine, loquat is sweet, sour and cool in nature, and belongs to the spleen, lung and liver meridians. It has the effects of moistening the lungs and lowering the qi (moisturizing the lungs and bringing down the upward lung qi), quenching thirst and generating fluids. It can be used for symptoms such as coughing and wheezing caused by lung heat, vomiting and thirst, so it is useful for relieving cough caused by lung heat. The loquat is usually used in medicine after a certain degree of concoction, and usually used in the form of decoction, in order to have a better effect. In addition, loquat has a limited effect on relieving cough, if the cough symptoms continue to be unrelieved, it is recommended to go to the regular hospital to receive timely treatment. It is important to note that loquat should not be taken by people with a weak spleen. Chinese medicine should be taken under the guidance of a physician, not on their own.
