Essence Wu capsule has some damage to the liver because it is a proprietary Chinese medicine preparation, mainly used for insomnia, hair loss and excessive graying of hair caused by kidney yin deficiency in patients. For the taking of Jing Wu capsule, if you are a normal person, you can consider taking it in moderation, but do not take it continuously for more than a month. If after a month the patient still wants to continue taking it, it is recommended to stop taking it for two weeks before considering taking further medication, which will have less impact on liver function and kidney function. In addition, for patients with viral hepatitis or other underlying hepatobiliary pathologies, it is recommended to take as little or no other drugs as possible, including Jing Wu capsules, because for the liver, the general reserve function is insufficient and may cause liver insufficiency and liver failure in patients after taking the drug. If the patient needs to take Jing Wu capsule, it is recommended to regularly observe the liver function and kidney function to see if there is liver function and kidney insufficiency, if there is, you should actively stop the drug and take a certain amount of liver and kidney-protective drugs for treatment.
