For patients with cough symptoms, they can eat pears, loquats, grapefruit and other fruits in moderation. These fruits are not only rich in vitamins and trace elements, but are also considered by Chinese medicine to have the medicinal effects of clearing heat and detoxifying, moistening the lungs and dissolving phlegm, and clearing the throat. Ice sugar boiled pear water and Sichuan shellfish stewed loquat are commonly used in life to help stop cough. Patients should minimize the consumption of hot or too much sugar fruits such as oranges, lychees, longan, cherries, mangoes, durian, sugar cane, etc. to prevent irritation of the airway mucosa after intake, leading to aggravation of cough symptoms and causing throat discomfort and increased phlegm. Patients with cough and throat discomfort can drink honey water, lemon water, fat sea water, etc. in addition to fruits. If the cough is severe or accompanied by coughing phlegm and redness of the throat, you can take medicines such as honey-refined Chuanbei loquat paste and pulmonary cough for treatment under the guidance of a doctor. If there is a bacterial infection, antibiotics can be used for anti-infection treatment. Also, avoid eating too much spicy and stimulating food and talk less to let your voice get enough rest.
