text: Liver and Kidney Yin Vacuity \nThis pattern appears as the combined Yin deficient symptoms of both the Liver and Kidney, and is common in depleted or older patients. Aging, reproduction, and excessive sexual activity deplete the Kidney, while the stresses of life and emotional challenges tax the Liver. Together, the diminishment of these two vital substances is responsible for numerous natural phases such as menopause, and the overall aging process. Deficient Yin of these combined organs will result in dryness of all their associated bodily tissues, including the skin, hair, eyes, and diminishment of sexual fluids. As the Liver rules the eyes, visual problems such as loss of acuity, blurry vision and dry eyes result. As the Kidneys rule the ears hearing problems, such as tinnitus or hearing loss develop. Other symptoms include dizziness, dry mouth and throat, seminal emission, insomnia, and low back or knee ache. Also included will be heat signs due to Empty Fire rising out of Yin vacuity, such as warmth in the palms of the hands, soles of the feet or the chest center. The tongue will be red, possibly with cracking, and have little coating. The pulse will be fine and weak.
