phlegms

痰, 黏液

the thick mucus that is formed in the nasal and throat cavities, usually secreted in excessive amounts as a result of common cold

Phlegm is a thick and sticky mucus-like substance produced by the respiratory system. It is primarily composed of mucus secreted by the mucous membranes lining the airways. Phlegm serves as a defense mechanism to trap and remove foreign particles, such as dust, bacteria, and viruses, from the respiratory tract. It can be coughed up or expelled through sneezing, aiding in the removal of irritants and helping to keep the airways clear. Changes in the color, consistency, or amount of phlegm can provide indications of certain respiratory conditions or infections.

The common cold often causes an increase in phlegm production, leading to congestion and coughing.
