Cough patients can eat sugar cane, especially sugar cane juice, which can produce saliva to quench thirst, moisten the lungs and resolve phlegm, and may also play a therapeutic role in the symptoms of cough patients. However, if patients have frequent coughs, when chewing sugar cane, we must pay attention to avoid the residue of sugar cane from entering the trachea to cause cough aggravation, and try to drink some sugar cane juice, which is safer and will absorb its nutrients more thoroughly. In addition, patients with cough should drink more water, improve circulation, and choose symptomatic treatment according to the diseases that may cause cough at present. The treatment of fruit is only an aid, but if the disease is serious, the choice of medicine is also essential.
