Question
My 3-year-old child has a cough, especially at night, accompanied by phlegm. However, the child is unable to cough up the phlegm. After a week of injections, there was only slight improvement for two to three days. There is no fever, and there are no special abnormalities in eating or drinking. The stool is less frequent and somewhat dry. Can the child take Sichuan Fritillary Lozenge? Do we need to combine other medications for treatment?
