You can eat a mixture of roxithromycin, promethazine and licorice, and mix it with Fritillaria cirrhosa, almond, pear and crystal sugar to make soup, which has the function of relieving cough, resolving phlegm and moistening lung. In the meantime, drink more water, eat more fresh fruits and vegetables, and don't eat spicy food, especially fish, shrimp and mutton. I wish you a speedy recovery.
