For the judgment of kidney yin deficiency and kidney yang deficiency, Chinese medicine practitioners mainly judge by clinical symptoms, tongue and pulse. 1. Clinical Symptoms: Patients with Kidney-Yin deficiency mainly show soreness and weakness of the waist and knees, five heart-heat (heat in the hearts of the hands and feet, and self-consciousness of the heart and chest), dryness and bitterness of the mouth, night sweating (sweating abnormally after going to sleep, but sweating stops after waking up), and deafness and tinnitus. Patients with kidney yang deficiency mainly show coldness in the waist and knees, long and clear urination, and coldness in the limbs. 2. Tongue and pulse: Patients with kidney yin deficiency mainly show red tongue with little moss and fine pulse (the pulse becomes narrower and thinner and the rate is accelerated). Patients with kidney yang deficiency have a pale tongue with white fur and a sluggish pulse. For patients with kidney deficiency, it is recommended that they go to a regular hospital and be treated under the guidance of a professional physician.
