Eating dragon fruit does not aggravate cough symptoms, which generally occur due to a certain intensity of stimulation of cough receptors, which are mainly located in the throat, as well as in the airways such as the bronchi and trachea. Cough symptoms can occur if the pharynx is strongly stimulated or if the airways are strongly stimulated, including when an acute inflammatory reaction occurs in these areas. Dragon fruit is a common fruit that is richer in vitamins as well as water, and is not strongly irritating, so it does not cause irritation to the throat, and the richness of water and vitamins has a certain auxiliary effect on the reduction of congestion and edema in the throat. Therefore, cough patients eat dragon fruit, not only will not aggravate the cough, for the cough symptom reduction has a certain auxiliary effect.
