If you feel phlegm all the time, you should first understand from which location the phlegm is produced and give symptomatic treatment to get good results. If it is a case of rhinitis where nasal snot may back up into the pharynx and cause phlegm, you can consider using drugs for rhinitis to reduce the outflow of secretions in the nasal cavity, and use nasal sprays such as endosolvadex or Reynocort to spray the nasal cavity. If phlegm is caused by pharyngeal cavity, when there is pharyngitis or pharyngolaryngitis, the inflammation of the pharynx will stimulate the increase of secretion in the throat, which will also lead to phlegm, and it is usually necessary to treat pharyngolaryngitis with drugs, such as glycyrrhiza bingmei tablets and busulfan oral solution. There are also cases of sputum caused by infection in the lungs, which are usually caused by inflammation in the lungs and coughing out sputum.
