The generic name of Tian Qing Gan Ping is called Diammonium Glycyrrhizate Enteric Capsules and is generally recommended to be taken before meals. Diammonium glycyrrhizate enteric capsules are liver-protective drugs, and the main ingredient, diammonium glycyrrhizate, is absorbed in the intestinal tract without being affected by food. However, it is a serious irritant to the stomach, mainly manifested by nausea, vomiting, abdominal distension and loss of appetite. Therefore, it is made into an enteric preparation in order to reduce adverse reactions in the stomach. Taking diammonium glycyrrhizate enteric-coated capsules before eating can ensure that it does not dissolve in the stomach but reaches the intestine before dissolving and releasing, which can effectively avoid the irritation to the stomach.
