 as a hexa-hydro-derivative of pyrazine

USE OF UNAUTHORIZED NAMES FOR VEGETABLE DRUGS AND flEDICINAL PLANTS. 



By henry H. RUSBY, M. D., 

 Professor of Physiology, Botany, Pharmacognosy and Materia Meaica, at New York College of Pharmacy. 



TN one way or another everyone who 

 ■^ has much to do with pharmacy suffers 

 from the custom noted in this title. The 

 clerk wastes valuable time in a vain 

 search for an unrecorded name, although 

 the article itself may be well-known to 

 him under its ordinary title, (as "Cuca" 

 for Coca,) and the customer — perhaps a 

 physician — is sent away annoyed and dis- 

 satisfied. Or, perhaps misled by the im- 

 proper use of a common name, the clerk 

 is led to furnish an article not desired 

 by the customer, (as "Zanthorhiza" in- 

 stead of Hydrastis, for Yellow Root,) 

 and, however correct his action, suffers 

 from all the discredit of having committed 

 an error. The employer, in making his 

 purchase, orders one thing and receives 

 another, (as "Cherry Laurel" instead 

 of Myrcia, for Bay Leaves,) or orders 



something supposed to be new — the phy- 

 sician being, geuerall}^, in this case the 

 one principally involved — and gets an 

 old and generally discarded article, or 

 one possibly already in stock, (as "Eri- 

 geron" for Pride Weed). 



Not infrequently is the physician made 

 the victim ot a direct fraud, (as in the 

 case of "Ditana digitifolia" which does 

 not exist,) in which case he can never 

 quite free himself from a feeling towards 

 the druggist as though the latter had 

 been a confederate in it. True, the drug- 

 gist has acted merely as an agent — and an 

 unconscious one — but then he "ought to 

 have known," and his knowledge should 

 have protected his over-credulous broth- 

 er, who is not expected "to be posted" 

 on such matters.
