This symptom is very common and is commonly known as blood heat.

It is caused by kidney yin deficiency and insufficient body fluid secretion. You can drink winter melon stewed with black chicken soup and stir-fry watermelon rind to slowly recover. You can also consult a traditional Chinese medicine doctor for a prescription. At ordinary times, you should pay attention to eating less animal liver, beef, mutton, seafood and other foods, and mainly eat light foods.
