"Herbal Xuan Tong" records that pears "clear the heat of the five internal organs for the living, and nourish the yin of the five internal organs for the ripe ones". The dry air in spring and autumn is the season when respiratory diseases, especially lung diseases, occur frequently. Chinese medicine experts believe that yellow pears in late autumn can remove lung garbage and enhance lung resistance. Therefore, experts suggest that eating about 400 grams of yellow pear in late autumn every day can play a variety of nutritional and health-care roles, such as invigorating the stomach and promoting digestion, moistening the lungs and relieving cough, clearing away heat and resolving phlegm, sobering up and preventing cancer.
