The way to nourish the liver is to drink Pu-erh tea, green tea, etc., but tea has only a secondary effect on liver metabolism, and can not play a major role. Pu-erh tea, green tea has a large number of tea polyphenols, which can promote its own oxidative metabolism, and a large amount of tea can promote blood circulation, promote the metabolic function of the liver, to ensure the normal operation of liver cells, and promote the recovery of liver cells. However, in general, drinking tea is only a mild aid to liver function. Drinking tea does not treat or improve liver function injury when it is severe. It is important to develop good habits in daily life to avoid damage to liver cells caused by smoking and drinking alcohol.
