Action and Uses of Balsams of Peru and Tolu. 



Externally, the balsams are stimulant, antiseptic and parasiticide. 

 Balsam of Peru is a useful remedy in alcoholic solution (1-8) for chronic 

 eczema of dogs. It may also be serviceable in ointment (1-8) for sore 

 teats in cows, or as an application to kill lice and the parasites of (sar- 

 coptic) mange and ringworm. 

 For mange or ringworm.

M. 



S. Apply externally 3 times daily. 



It is, undiluted, a most excellent stimulant and antiseptic dressing 

 upon wounds and ulcers. In fact there is no better agent for dressing 

 ordinary wounds. Occasionally renal inflammation follows its very ex- 

 tensive external use. 



Internally, the balsams are stomachic and carminative, and are elimi- 

 nated by the skin, mucous membranes and urinary organs, stimulating 

 these parts. They are therefore occasionally prescribed in chronic bron- 

 chitis, pyelitis and cystitis. The syrup of tolu is an exceedingly mild 

 preparation, but forms an agreeable vehicle for cough mixtures in canine 

 practice. The balsams may be administered in emulsion rubbed up with 

 either glycerin, mucilage, or white of egg and water.
