Hawthorn is not recommended for coughs because it is rather acidic and it is not recommended to eat overly acidic food during coughs. Firstly, overly acidic food tends to irritate the throat leading to the onset of cough or aggravate it. Secondly, acidic food has the effect of astringent phlegm, which makes phlegm less likely to be coughed out, thus aggravating the infection of the respiratory system and making it difficult to heal the cough, so it is better not to eat hawthorn during coughing. Once again, the acidity of hawthorn is relatively high and can easily cause too much acid in the stomach and intestinal tract, which is also not good for cough recovery. It is better to eat simple, light and easily digestible food or to eat fruits that clear heat and detoxify the body, such as pears, apples or grapefruit. Finally, a light diet is needed. You can drink rice porridge or millet porridge and eat fresh vegetables rich in vitamins, such as green vegetables and cauliflower.
