I tried this way to cure 咽炎. when I felt 咽炎 started at very beginning, I went to buy lime (no matter whether it is yellow or green), then I got its juice from one entire lime without added any water and drunk it. I tried two or three times a day. it would get rid of 咽炎 away, since I have bothered by it fro many years. hope it works fro you too.
