physiologic standardization. Most of the indica- 

 tions for a narcotic are better met with opium; but 

 cannabis may be used if for any reason opium 

 is contraindicated. In certain cases, more notably 

 neuralgic ones, cannabis relieves pain more promptly 

 than does opium. Vesical spasm is the one indica- 

 tion where cannabis is almost universally preferable 

 to other drugs. In the earlier stages of gonorrhea 

 the drug is a good agent to produce sedation. Some 

 cases of dysmenorrhea are markedly relieved by 

 cannabis. 



Dose: Tr. 5 to 15 minims; fl. % to 2 minims. 



CAPSICUM 



CAYENNE PEPPER, capsicum fastigiatum. Official. 

 Capsicum is a useful rubefacient suitable for pro- 

 longed application because never blistering. Cap- 

 sicum is not sufficiently valued as a stimulant, 

 especially in gastric inactivity, frequently noted in 

 long-standing cases of malaria. Dose: 1 to 5 grains. 



CARBO LIGNI 



CHARCOAL. Official. Used in flatulence with fetid 

 breath and offensive dysenteric discharges. Char- 

 coal may also be added to poultices, which may then 

 have a disinfectant action. Dose: 10 to 60 grains. 



CARYOPHYLLUS 



CLOVES, Eugenia aromatica. Official. Dose: 1 to 

 5 grains. Oil of Cloves is markedly carminative and 

 is of great value for its anesthetic and caustic effect 

 on exposed nerves in carious teeth. Eugenol, an hy- 

 droxylated terpene, is the active agent.
