Deficiency of yin will lead to yin deficiency and fire, such as dry mouth, dry eyes, even mild tinnitus, hot flashes, hot hands and feet at night, irritability, not easy to fall asleep, and dreaming after sleep, which are symptoms of yin deficiency and fire, and can be taken with American ginseng as a tea substitute or chewing. After making water with a small amount of American ginseng, if it is combined with sleep disorders and excessive dreaming, it can be added with Schisandra chinensis. If there are obvious symptoms of yin deficiency and fire, such as dry mouth and eyes, you can add wolfberries. If you feel that your spleen qi is weak, your appetite is poor, or your stools are loose, you can use those that strengthen the spleen and dissolve dampness, such as patchouli, pellitory, and sand nuts.
