CALUMBA 573 



For cattle the above prescriptions are as serviceable as for 

 horses, but require to be given in somewhat larger doses. 

 For sheep gentian is a very useful stomachic, and when 

 prescribed with salt arrests for a time the progress of liver- 

 rot. It is a valuable bitter tonic for dogs prostrated by 

 reducing disorders. 



DOSES, etc. For the horse, 3ij- to i. ; for cattle, i. 

 to gij. ; for sheep, 3i. to 3iij. ; for pigs, 3ss. to 3i. ; for 

 dogs, grs. v. to grs. xx., repeated twice or thrice daily. 

 The carefully-prepared Pharmacopoeia extract, infusion, 

 and tincture, flavoured with orange-peel and aromatics, 

 are frequently used in veterinary practice. The powder 

 is prescribed in bolus, prepared with treacle, glycerin, and 

 meal, or in infusion, made by digesting the powder during 

 several hours in hot water, and decanting the clear fluid. 

 A small addition of diluted alcohol ensures more thorough 

 solution and better keeping.

 starch. 



ACTIONS AND USES. Calumba is a bitter and gastric 

 stimulant. It promotes secretion of gastric juice and 

 improves the appetite in a manner similar to gentian. As 

 it contains no tannin it is devoid of astringency and may be 

 prescribed with preparations of iron. Like quassia, calumba 

 infusion may be used to destroy worms in the horse's rectum. 



DOSES, etc. Of the infusion (one of calumba to 20 of cold 

 water) horses and cattle take ij. to iv. ; dogs 3ij- to j.,
