You can eat honey when you have a cough, but you must be careful how you do it. Honey is very nourishing, it contains a lot of lung moistening things, and there are many immune substances that can help improve the body’s immunity and fight against external sensations. However, honey is very sweet, and this sweetness has a bad effect on the body, especially on the respiratory tract, which may cause irritation of the pharynx, or if the honey is too sweet during the discharge of phlegm, it may affect the smoothness of the discharge. So when you use honey, you must mix it with water to dilute it, and not use water that is completely boiling, but generally use water that is about 40 degrees Celsius to dilute the honey, and drink it while it is still hot.
