Doses. 



Fluidextradum Chimaphilce. D. 3ss — j ; 2.0 — i.O. 



Since the constituents are so similar to those of buchu the action 

 and uses are practically identical with it. 



* PAREIRA 

 Synonym. Pareira Brava 



The roots of Chondrodendron tomentosum, a climbing tree grow- 

 ing in Brazil and Peru. They contain as an active principle an al- 

 kaloid, buxin and tannic acid. The action and uses are similar to 

 buchu. 



Cantharis, Cantharides. Since cantharides has a more typi- 

 cal and important action it will be studied in detail in another 

 group. In moderate doses it is a stimulant to the genito-urinary 

 tract, but in large doses is a severe and dangerous irritant. Toxic 

 doses or even large ones are irritant to the gastrointestinal tract, as 

 well as to the genito-urinary tract. The most important and typical 

 results of large doses are : gastro-enteritis, with pain, nausea, vomit- 

 ing or purging. Upon the genito-urinary tract it may cause 

 nephritis, dysuria, frequent micturation, hematuria and albumin- 

 uria. It has been recommended as a stimulant to the genito-urinary 

 tract but is rarely used for this purpose, except as an aphrodisiac. 



*ZEA 



Synonym. Cornsilk 



Zea or cornsilk is the stiles and stigmas of Zea mays (Indian 

 corn). Its activity is due to a resin and maizenic acid. 



Fluidextradum Zeoa. D. 3ss — ij ; 2. — 8. 

 Decodum Zeoe, 5 per cent. D. §j — ij ; 30. — 60. 



Cornsilk really belongs to the group of diuretics. It is a feeble 

 diuretic and sedative to the genito-urinary mucous membrane. It 

 may be of some use in acute cystitis and various forms of nervous 

 irritibility of the bladder, but is of little value in veterinary medi- 

 cine.
