Cough itself needs to be divided into wind-cold and wind-heat coughs, and watermelon juice is a product that clears heat and quenches thirst, especially in summertime. Summer coughs are more common in wind-cold and wind-heat coughs, and also include summer dampness coughs. Drinking watermelon juice when you have a cold or hot cough can quench your thirst, moisten your lungs and dissolve phlegm, which can help to treat and relieve coughs. Watermelon juice can also be used as an adjunctive treatment for summer coughs, which are unique to summer. Of course, coughs need to be further treated according to the specific cause of the cough, and watermelon juice can be used as an adjunctive dietary therapy in conjunction with it if necessary.
