Excessive use of expectorants may interfere with the self-cleaning function of the respiratory tract."This view has triggered widespread discussion in the medical community and is in sharp contrast to the habit of self-medication by some netizens.
Professor Wang from Beijing University of Chinese Medicine suggested:"White phlegm mostly belongs to cold syndrome. You can eat ginger, tangerine peel and other warm ingredients appropriately, but it needs to be treated based on syndrome differentiation and avoid treating one person at a time."This suggestion received a large number of reposts and likes from TCM enthusiasts on the Xiaohongshu platform.
