Strictly speaking, eggplant is not significantly effective in treating cough. Eggplant is a cold vegetable and has a certain clearing and detoxifying effect after eating it, which has some auxiliary effect in helping to treat cough, but the cough does not relieve the phenomenon. The symptoms of cough should also be actively treated with medication, such as cough caused by respiratory infections, which need to be based on the type of infection. Choose appropriate antibiotics and antiviral drugs for anti-inflammatory treatment. In addition, if the cough is caused by cough variant asthma, inhalation of terbutaline sulfate and budesonide should be used to relieve the cough. In addition, if the cough is allergic, anti-allergy medications such as loratadine are needed for relief. Eating eggplant, which is rich in vitamins, vitamin C or vitamin B, can help the body to build up resistance and thus promote recovery from infection, so it is helpful in aiding the treatment of cough.
