ABSTRACT

Although no effort is made to describe pharmacognosy in an introductory chapter, it immediately becomes obvious according to this textbook that pharmacognosy is the study of all vegetable drugs. Most of the emphasis has been placed on the botanical characterization of the drugs, especially their morphology and histology. The student using this textbook must be familiar with the fundamentals of descriptive botany. Though less attention is devoted to the constituents and uses of these drugs, nevertheless these data are brief and complete.

The drugs to be treated are arranged on a taxonomic and also on a morphologic basis. In the beginning the drugs are grouped under the thallophytes and pteridophytes. The spermatophytes are divided into a number of morphologic groupings such is rhizome and roots, tubers, woods, barks, herbs, leaves, flowers, fruits and seeds. Each of these groups is subdivided into monocotyledons and dicotyledons, and, finally, the drugs are listed
