The season of fright is warm and cold, and the climate is relatively dry, which makes people thirsty and cough due to exogenous factors. There is a folk custom in China to eat pears on frightened days. Experts say that raw pears are cold and sweet, and have the effects of moistening the lungs and relieving cough, nourishing yin and clearing heat. In addition, patients with cough can also eat lotus seeds, loquat, Siraitia grosvenorii and other foods to relieve pain. Diet should be light, and it is best not to eat greasy food. Irritating foods such as peppers, onions and garlic should also be eaten less.
