Commonly taken in effervescent solution. It is about the least disagreeable of all purgative medicines. Apothecaries mostly keep it already dissolved, in tightly corked and wired bottles. More convenient for keeping in a family is the solid granular citrate of magnesium '. which is to be dissolved when taken. Dose, of the bottled solution, a wine-glassful (more, or less, according to the amount of purging needed). Of the granular citrate, from a teaspoonful to a table-spoonful. In the latter dose, it is quite an active cathartic; although not so rapid in its operation as some other medicines; and all persons are not alike susceptible to its action.
