Chronic pharyngitis is difficult to cure, so it is important to maintain a light diet and follow your physical condition. It is recommended to take one vitamin C tablet a day, especially when eating spicy food, or drink plenty of water to keep your throat clean. You should also eat fruits containing C, such as pomegranate, kiwi, Apples, etc., smoke less, and when you are really feeling uncomfortable or in pain, you should consider taking medicines, such as Yinhuang Granules, Zhenhuang Pills, Rubesque Grass Tablets, Pharyngitis Tablets and other Chinese patent medicines
