What foods help relieve cold symptoms, coughing, and excessive phlegm more quickly?

For colds accompanied by coughing and excessive phlegm, drinking an appropriate amount of brown sugar–ginger tea may help alleviate cough symptoms associated with the common cold. Roasted tangerines are also beneficial, as tangerines possess expectorant and antitussive properties. Roasting eliminates their naturally cold and raw nature, thereby avoiding throat irritation while enhancing their cough-suppressing effect and reducing phlegm production. Additionally, consuming more fresh fruits and vegetables—rich in vitamins—can support faster recovery from the common cold.
