Maltum, Malt, is now official. It is diastasic, tonic, nutrient, and (in the form of Extractum malti, U. S. P.) an excellent vehicle for disagreeable drugs. The so-called malt tonics made by brewers differ little from the better grades of beer, ale, and porter. Several drug houses sell liquid malt preparations rich in diastase and containing very little alcohol.
