Watermelon cream lozenges cannot cure cough, but can only moisten and cool the throat, so it is generally appropriate to use watermelon cream lozenges if you feel uncomfortable with your throat when you talk more, or when the environment is dry and you drink less water. However, if there is inflammation in the respiratory tract, coughing or even phlegm, watermelon cream lozenges are not suitable. Watermelon cream lozenges are colder, so they tend to cause airway reaction and tracheal contraction, which is not conducive to the discharge of phlegm produced by inflammation in the airway. In addition, watermelon cream throat lozenges are cold, and the saliva swallowed after watermelon cream throat lozenges contain a lot of this benign medicine, but also easy to hurt the spleen and stomach, which is not good for the improvement of respiratory diseases, because the spleen and stomach is the mother organ of the lungs, if the spleen and stomach are injured, it will affect the recovery of lung disease, so try not to use watermelon cream throat lozenges when coughing.
