CHENOPODIUJt 439 



expensive for general use for horses. Santonin is often remedial in in- 

 continence of urine in young animals, when belladonna fails,' and is fre- 

 quently beneficial in the treatment of amaurosis. 



Class 3. — Used to Expel Round and Hook Worms. 



Chenopodium. American Wormseed. (Non-offlqial.) 

 The fruit of Chenopodium arabrosoides, a perennial plant growing in the 

 United States and the West Indies. The seeds contain a volatile oil of an aro- 

 matic and disagreeable odor, to which the action of chenopodium is due. 



Dose.—H., 3ii-iii, (8-12) ; D., Tlliii, (0.2), per 2.2 lb.; Cats, TTli-iii, (.06-0.18). 



The drug has been used extensively in the treatment of hookworm 

 in man. Cases of poisoning have occurred with nausea, vomiting, diar- 

 rhea and dysentery, weakness, staggering, paralysis, stupor and coma. 

 Ascaridole the active principle, depresses the muscular tone of the bowels, 

 heart and vagus center. Treatment consists in the use of castor oil, caf- 

 feine and strychnine. The oil is given to dogs on sugar or in capsule. 



Hall and Foster have found oil of chenopodium the most successful 

 agent against ascarida in dogs, giving 0.2 mils per kilo live weight; and 

 the best remedy in lambs for hookworm in the same dosage. Dogs are 

 starved for 24 hours and given a dose of castor oil before the chenopodium 

 is administered. 



For mixed infestation with intestinal parasites in dogs (ascarids, 

 hookworm, whipworm) the same investigators discovered that a combina- 

 tion of chloroform and oil of chenopodium in the dose of 0.2 mils per kilo 

 (TTtiii per 2.2 lb.), of each, with castbr oil, 30 mils, was the best remedy 

 as follows for 22 lb. dog: 



Olei chenopodii. 



Chloroformi aa 3ss. 



Olei ricini 3i. 



M. 



S. Give at one dose after starving 24 hours. 



Against hookworms in dogs, chloroform was found most efficient in 

 the same dose (0.2 per kilo) ; more so than chenopodium. Chenopodium 

 is very efficient against round worms in hogs, giving about 1 minim to 

 every 2 lbs. live-weight on the feed. The hog should be previously fasted 

 for 24 hours and fed individually. The oil of chenopodium is also very 

 successful against hookworm and stomach worms of sheep, given to them 

 in the same dosage (0.2 mils per kilo) as for dogs, in a glass of milk. 



Spioelia. Pinkroot. 



Spigelia or pinkroot is the root and rhizome of Spigelia marilandica (Caro- 

 lina pink), growing in the Southern United States. 



Spigelia is used against round worms and should be followed by a purge. 

 For this purpose it is often given with senna. 



Round worms. Dogs. 



Fluidextracti spigeliae at sennse gi. 



Sig. Two teaspoonfuls as dose. 

 It has some toxicity for higher animals and may cause poisoning resembling 

 that of belladonna, as dilatation of the pupils, stupor, coma. It contains an alka- 

 loid, spigeline, a bitter, volatile oil and tannin.
