Licorice tablets are generally not suitable for cough and phlegm. Licorice tablets, also called compound licorice tablets, contain a variety of ingredients, mainly from traditional Chinese medicine, such as camphor, anise oil, opium powder and other ingredients, which have cough suppressing and expectorant effects and are used for coughs caused by a variety of reasons, including bronchitis and bronchial tuberculosis. Since licorice tablets contain opium powder, a central cough suppressant ingredient, which mainly inhibits the cough center and plays a strong cough suppressant role, they are not suitable for patients with cough and phlegm. Because if coughing and phlegm are present, strong cough suppressant is not conducive to the discharge of phlegm and even causes phlegm to block the airway, which can produce asphyxia in serious cases. Therefore, licorice tablets are generally suitable for patients with dry cough and no phlegm.
