If you have a cough with yellow pus phlegm, you have a wind-heat cough. Brown sugar and ginger are both hot foods, which can aggravate the symptoms of wind-heat cough or aggravate the symptoms of wind-heat cold, so you should never drink brown sugar and ginger tea during this period. However, if you have a wind-cold cough, you can drink brown sugar and ginger tea to treat it. A wind-cold cough is caused by external wind-cold, and you cough up white, thin phlegm, so drinking brown sugar and ginger tea can remove the cold from your body and help you recover from a wind-cold cough or wind-cold. However, you should not drink too much brown sugar ginger tea, because it is a strong stimulus to the stomach, and if you drink too much, it is easy to produce stomach discomfort, which is not conducive to recovery.
