Convincing liquid is a classic gastric mucosal protector. This drug acts as a mucosal barrier. Therefore, this drug must be taken before a meal to be more effective. This is because when fasting before a meal, there is nothing else in the entire stomach. After oral administration of Healing New Liquid, this liquid can be evenly sprayed on the surface of the stomach, forming a protective film of the stomach, which is equivalent to a shield, forming a protective barrier. After eating, or after the secretion of stomach acid, this mucosal barrier can play a very good role in protecting the lower gastric mucosa. At the same time, Healing New Liquid can also repair the gastric mucosa, and the drug acts directly on the lesion area to provide a quick repair to the disease. If taken after a meal, the effect of the drug may be greatly reduced due to the large secretion of stomach acid and the stimulation of food.
