2 TABLE OF THERAPEUTIC AGENTS 



aromatic, bitter, acrid, sweet, and mucilaginous drugs are brought to- 

 gether, (b) Classification into subgroups based upon structural char- 

 acteristics. Here drugs having similar structure are found associated. 

 In the table having this arrangement the official drugs only are found. 

 Appended to each there is a physical description in the fewest possible 

 terms such prominent terms as are used in describing the physical and 

 structural characteristics. 



Each drug has a number, so that a ready reference to the same drug in the 

 body of the work is made easy. Here a fuller description is found. 



Instructors in pharmacognosy who use this book are recommended to employ 

 this conspectus and to have the students use these numbers. When labeling the 

 drug (or its container) for class work, these numbers should be employed. The 

 experience of the author in teaching the subject under consideration has been 

 most favorable to this method. By the use of the numbers at first, the student 

 quickly grows to learn, not only the drug, but the place in the system to which 

 it belongs. The subject grows in interest until he is able to recognize the drug 

 and to properly classify it. 



IV. Botanical. By this arrangement drugs belonging to the same 

 natural order are brought together. In subdividing these orders botanical 

 relationship is emphasized to as large an extent as is practicable in deal- 

 ing with drugs from a pharmaceutical standpoint. From the point of 

 view of the scientist this is the ideal system. This method has been adopted 

 in the body of this work. 



Geographical. Drugs are rarely classified according to the locality of their 

 occurrence. It is, however, instructive to the student to refer individual, or 

 classes of drugs, to their locality. Drugs of ancient times were obtained chiefly 

 from Asia. Many of these have survived, and are official to-day; notably aloes, 

 myrrh, etc. With the discovery of the new world many important drugs were 

 made accessible. Geographical classification is therefore of interest from many 

 points of view. The presentation of this subject is facilitated by outline maps 

 with the drugs indicated in their natural localities. As an example of such a 

 map, see Cinchona. 



Alphabetical Arrangement. In all the standard books of reference, such as 

 the "Pharmacopoeia" and the "Dispensatories," a strictly alphabetical arrange- 

 ment is followed, no attention being paid to systems of classification. The ar- 

 rangement is made wholly subservient to quick and ready reference. 



In the following order four classifications will be presented: i. A synop- 

 sis of therapeutical agents. 2. Chemical agents. 3. Classification of 

 organic drugs, as indicated under (a) and (6). 4. Botanical arrangement, 

 where drugs will be treated at some length.
