Tinnitus and night sweats mostly belong to kidney yin deficiency, but rarely seen in kidney yin and yang deficiency. Patients with Kidney-Yin deficiency have tinnitus with a high pitch and sharp sound, which tends to appear at night, accompanied by heat in the palms and feet, dry mouth and bitterness, yellow urine, and hot flashes of bone steam, mainly in the afternoon, with the above manifestations apparent after the afternoon. These patients are mostly caused by injury to Qi and Yin. It is mainly reflected in the following aspects: 1, lack of exercise: Yang Qi is not stored, and the growth of Yin Qi is restricted; 2, eating food on fire: such as spicy stimulation, barbecue, greasy food, will lead to increased blood viscosity, which leads to heat stasis, poor Qi flow, causing injury to Qi and Yin resulting in Yin deficiency; 3, false fire injury to the liver: anxiety, depression, indulgence, staying up late, can cause false fire to rise and lead to loss of Kidney Yin.
