Patients with significant phlegm in the throat usually have difficulty draining it out in the form of nasal mucus, but if mucus or mucopurulent nasal mucus is present in the nasal passages, it may be drained out in the form of phlegm. Some patients may experience repeated backward flow of nasal mucus in the nasal passages into the throat, resulting in repeated increase of phlegm in the throat, which may be excreted by coughing or throat clearing action. If the patient has obvious purulent nasal discharge or symptoms of pus phlegm, further treatment with antibiotic medication is often required. To reduce the production of inflammatory secretions from the underlying etiology, mucus-promoting drugs, such as eucalyptus lemongrass enteric softgels, can be used in conjunction.
