Milk of magnesia is a name given to magnesium hydroxide – an inorganic compound with the formula, “Mg(OH)2”. It forms a milk-like appearance when in suspension, hence the name. The solid mineral form of magnesium hydroxide is brucite [Mg(OH)2] which occurs in clay minerals especially in chlorite. Brucite occupies the interlayer position which is normally occupied by monovalent and divalent cations such as Na+, K+, Mg+ and Ca+ in chlorite. In this manner, chlorite interlayer is cemented by brucite and can neither swell nor shrink (Zumdahl, 2009).

Milk of magnesia is used as an antacid to neutralize stomach acid. Hydroxide ions from the Mg(OH)2 combine with acidic hydroxide (H+) ions produced from hydrochloric acid by parietal cells in the stomach to produce water. It is made into capsules and chewable tablets for use against constipation and indigestion ([[:File:UNN_Medical_Geology_Fig_16.png|Figure 16]]).
