Action and Uses. — Areca nut is an anthelmintic more 

 commonly classed as a taeniacide, but capable of killing 

 round-worms satisfactorily. It acts more successfully as a 

 vermicide in dogs than in the case of the larger animals. 

 Areca nut is an astringent in small doses, but large amounts 

 induce catharsis. When the drug is used as an anthelmintic 

 the animal should be deprived of food for 24 hours previous 

 to its administration. The powder is given to dogs in milk, 

 frequently with oleoresin of male fern in small quantity. If 

 purgation does not follow the use of areca nut tvithin a short 

 time, a dose of castor oil is indicated. The fluid extract is a 

 more convenient preparation. 



Arecoline hydrobromate (CgHigNO, H Br) has been 

 recently employed subcutaneously — H., gr.^-i. (.02-.06) ; D., 

 S^-w'tV (•001-.005) — as a rapidly-acting cathartic, exciting 

 peristalsis, in colic and indigestion of horses, and in gastritis 

 (" Fardel bound ") of ruminants. The results so far reported 

 have been favorable, but final judgment must be deferred 

 until further trials are made. In 1 per cent, solution the 

 alkaloid is used in the eye as a myotic.
