After reading your description, your sore throat is caused by lung fire. Just nourishing yin and clearing lung heat can solve the problem. Don't eat hot food in diet, such as greasy, fishy and spicy. Diet should be light. Mainly cold food, such as melon, towel gourd, bitter gourd, lotus root, pear, watermelon, grapefruit and so on. Especially eating more pears and grapefruit in the afternoon can reduce lung heat and clear internal fire, which is very beneficial to you. In daily life, you should go to bed early and get up early, and don't stay up late, which can make internal fires difficult to live. Most people who are prone to get angry or have a sore throat are caused by staying up late. Decocting 30g of Mulberry Leaves and 0g of Ophiopogon japonicus15g with water four to five times a day can reduce lung heat and clear lung fire. You can also drink cassia tora chrysanthemum water (cassia seed15g, chrysanthemum morifolium10g) frequently every day, which can clear the internal fire, and specifically aim at the sore throat caused by lung heat (liver belongs to wood in five elements, lung belongs to gold in five elements, and wood fire burns lung). If you do as mentioned above, the sore throat will disappear and return to normal. That's my answer to your question. Thank you.
