This textbook was originally published for the purpose of preparing students for pharmaceutical examinations. This latest (fifth) edition nevertheless covers the field of pharmacognosy satisfactorily, and in addition contains discussion of such topics as: London commerce in crude drugs, enzymes found in vegetable drugs, chemistry of drug constituents, drug extraction, fluorescence and chromatographic analysis, and exercises on the evaluation of crude drugs. In addition, 10 maps are given (at the end of the text) showing the distribution of crude drugs throughout the world.
The text has been "revised in accordance with the U.S.P. XIII, 1947, and the B. P. 1948."
