GUAIACUM. The wood and resin. The 

 former is sometimes employed in human me- 

 dicine, as an ingredient in alterative decoc- 

 tions, but never in veterinary practice. The 

 resin, commonly called gum guaiacum, is 

 sometimes used as an alterative. Farriers 

 employ it also in what they suppose to be 

 rheumatic lameness, but without any advan- 

 tage, I believe. Rheumatism seldom at- 

 tacks horses : when it does occur, purga- 

 tives, with moderate exercise, are the best 

 remedies. 



The dose of gum guaiacum is from half 

 an ounce to six drams. 



There is a volatile tincture of guaiacum 

 sold in the shops, which seems better adapt- 

 ed to rheumatic complaints than the gum 

 alone; but its use should be preceded by a 

 purgative. 



The dose is one ounce and a half.
