The present disclosure provides a hydrogel tablet for relieving alcoholism and protecting the liver as well as the preparation process and application thereof. The present disclosure firstly provides a composition with the effects of relieving alcoholism and protecting the liver, which comprises the following components on the basis of weight parts: 20˜40 parts of chitosan, 25˜55 parts of sodium alginate, 3˜20 parts of gelatin, 1˜10 parts of calcium carbonate and 0.05˜0.5 parts of gallic acid. Based on this composition, the present disclosure further provides a hydrogel tablet for relieving alcoholism and protecting the liver. In the present disclosure, chitosan, sodium alginate and calcium carbonate are compounded at an appropriate proportion to form powder particles of chitosan/sodium alginate (shell)-calcium carbonate (core), into which are additionally added gelatin and gallic acid to get a product that is the hydrogel tablet.
