You can also take oral Chinese medicines, such as Baicalin Oral Liquid, Shuanghuanglian Oral Liquid, Pu Di Lan Anti-inflammatory Oral Liquid, Ban Lan Gen Granules, Qing Kai Ling Granules, Antelope Jiao Jiao Punch, etc., all of which have anti-viral effects. You can also take Chinese medicines, such as cough syrup, Chuanbei loquat extract, powerful loquat extract, and lung power cough combination, to relieve cough and resolve phlegm. If the cough is caused by bacterial infection, antibiotics such as penicillin, cephalosporins, macrolides and quinolones can be used for symptomatic treatment. You can also pass Bambuterol oral solution, which can dilute the phlegm, promote the discharge of phlegm and improve the efficacy of antibiotics.
