Pharyngitis is a manifestation of excess heat in the body. Therefore, we should avoid eating spicy and stimulating foods, smoking, drinking alcohol, and staying up late. You can eat some bitter foods that clear heat and relieve summer heat, such as bitter melon, mustard greens, white radish, fish mint, and isatis root, all of which have the effect of clearing heat and removing dampness. Gargling with salt water, holding it in your mouth for five to six minutes before spitting it out, can also be beneficial. If dietary treatment is ineffective, under the guidance of a doctor or pharmacist, you might use some traditional Chinese medicines that clear heat, detoxify, and remove dampness from the throat. If there are general symptoms such as chills, fever, or aversion to cold, it may be necessary to also use antibiotics in the treatment. (Medications should be used under the guidance of a clinical doctor; do not self-medicate blindly.)
