Whether eating fruit will aggravate a cough requires knowing whether the cough is a cold cough or a hot cough. A cold cough will certainly be aggravated if you eat cold fruits. A hot cough will certainly be aggravated by eating hot fruits. To determine whether it is hot or cold, a cold cough is one that is afraid of cold, coughs up white sputum or has a white runny nose, is not thirsty, and does not like to drink or sweat. A hot cough is a fear of heat, dry mouth, thirst, bitterness, love of water, and irritability. Cold coughs are best eaten with hot fruits, such as cherries and mangoes. Hot coughs can eat some cold fruits, such as pears, oranges and watermelons.
