REMOVAL OF THORN-HEADED WORMS FROM SWINE 11 



OIL OF CHENOPODIUM 



Oil of chenopodium in doses of 1 c. c. in 64 c. c. of castor oil failed 

 to remove any thornheads present in 17 pigs of an average weight of 

 80.6 pounds. The average dose of oil of chenopodium recommended 

 for a 100-pound pig for the removal of ascarids is from one-half to 

 1 fluid dram or from 2 to 4 c. c. The 1 c. c. dose, therefore, was well 

 within the limits of safety and may have been too small. Larger 

 doses- should be tested, although the results in these experiments 

 were not very promising. 



CONCLUSIONS 



The following drugs were entirely ineffective in the removal of 

 thorn-headed worms in the doses and manner used : Ethereal extract 

 of male fern, kamala, a hyperactive solution of iodine, oil of chenopo- 

 dium, and liquor cresolis compositus. 



Kamala extract had too little efficacy to be of any promise and 

 apparently does not warrant further test. 



Tetrachlorethylene should be tested in larger doses. 



Nicotine sulphate shows some promise for the removal of thorn- 

 heads, especially when given with carbon tetrachloride, and this com- 

 bination deserves further test. The doses of the nicotine sulphate 

 and carbon-tetrachloride mixture used were injurious to the animals 

 treated, but perhaps a satisfactory dosage and mode of treatment 

 may be developed.
