Andrews Liver Salts is a laxative and antacid for mild stomach complaints. It is sold as a powder which is added to water and mixed, creating effervescence, before being swallowed. The powder contains sugar; two antacids, sodium bicarbonate and citric acid; and a laxative, magnesium sulphate. The product is similar to Eno's salts and Kruschen salts, and a mild form of Epsom salts. The term "liver salts" or "health salts" is typically used for a laxative.
