Dr. Chen Yajuan
The main effects of licorice tablets are cough suppression and phlegm removal, commonly used for treating cough symptoms caused by conditions such as colds and pneumonia. The primary active ingredient in licorice tablets is licorice extract powder, supplemented with opium powder and camphor, which together protect the respiratory tract while providing antitussive and expectorant effects. Meanwhile, the star anise and fennel oil contained in licorice tablets can produce a beneficial reflex stimulation on the human airway mucosa, increasing secretion from respiratory glands and thereby diluting mucus.
