Kidney deficiency and liver fire refer to that on the basis of kidney yin deficiency, there is also liver fire exuberance, or it may be that liver fire exuberance consumes kidney yin. The method of recuperation is to invigorate the kidney yin while clearing the liver fire. For example, drugs for tonifying kidney yin, such as privet fruit, habitat, tortoise shell, turtle shell, etc., are used, and drugs for clearing hepatitis, such as chrysanthemum, mulberry leaves, and moutan peel, are used. In life, we should maintain a comfortable mood, calm mind, eat less warm and dry food, live in a disciplined way, and conform to the four seasons of Yin and Yang.
