COPAIBA 



COPAIBA, BALSAM of COPAIBA, an oleoresin de- 

 rived from Copaifera coriaceae, C. Guyanensis, C. 

 Langsdorfii, and C. qfficinalis all official as C. 

 species. 



Both the oleoresin and the oil of copaiba are apt 

 to induce erythemata and cause indigestion. Santal 

 has largely displaced them. They have been largely 

 esteemed in the treatment of gonorrhea, the balsam 

 in an average dose of 15 minims and the oil 8 minims, 

 in capsules or in the form of emulsion. These agents 

 are stimulants and antiseptics to the mucous mem- 

 brane of the urinary tract. 



Sterilization of the urinary tract is impossible, 

 especially in gonorrhea, the bacteria being deeply 

 lodged. Copaiba is relatively efficient, being ex- 

 creted slowly and not being dangerously irritant; 

 but it is useful only in more or less chronic forms of 

 gonorrhea, and in gleet. Winternitz taught that this 

 class of drug is effective more from decreasing the 

 number of leucocytes in the exudate than from any 

 antiseptic influence. 



CORNUS 



DOGWOOD, Cornus florida. Not official. A simple 

 bitter, in action similar to other bitters. See "Gen- 

 tian." Southern physicians esteem cornus as an 

 antiperiodic and employ it in malaria. Heat de- 

 stroys its active principle, cornin. Cornus is our 

 best indigenous substitute for cinchona bark. Dose : 



fl. Yi to 1 fluidrachm.
