Chinese medicine practitioners believe that tinnitus and night sweating (abnormal sweating after going to sleep and stopping after waking up), and cracked tongue with teeth marks are mostly related to insufficient yin fluid and inflammation of deficiency fire. For treatment, you can choose medicines with the effect of nourishing yin and lowering fire (nourishing yin essence and lowering fire), such as Zhi Bai Di Huang Wan. According to Chinese medicine practitioners, insufficient yin fluid can easily lead to the inability of fluid to travel up to the mouth and tongue, and the inability to moisten the tongue and the appearance of yin injuries such as cracks and teeth marks on the tongue. In addition, due to the deficiency of yin in the organism, yang is relatively hyperactive, and tinnitus occurs when deficiency fire is inflamed. At night, when the yang enters the yin, the vaporized fluid leaks out and night sweating occurs. Therefore, you can choose drugs that can nourish yin and reduce fire, such as Zhi Bai Di Huang Wan. Zhi Bai Di Huang Wan has the effect of nourishing yin and lowering fire, and can be used in the treatment of yin deficiency and fire (deficiency of yin and essence in the body, resulting in hyperactive fire), hot flashes (bursts of heat), night sweating, dry mouth and sore throat, tinnitus, spermatorrhea, and short and red urination (small amount of urine, dark yellow in color), and other conditions. The medicine should be taken with caution for pregnant women. For patients with tinnitus and night sweating and cracked tongue, it is recommended to go to regular hospitals for treatment under the guidance of professional physicians.
