INDIAN HEMP. 611 



Goulard's Extract. 



This popular name is sometimes applied to the liquor 'pluinhi 

 suhacetatis of druggists. 



For cracked heels, mud fever, etc., we may use 1 part of the 

 solution to 4 parts of olive oil, cream, or glycerine. 



Ichthyol, 



which is the ichthyo-sulphate of ammonium or of sodium, has been 

 greatly praised by German veterinary surgeons (" Journal of Comp. 

 Path.", June, 1900), as a remedy for cracked heels, grease, mallen- 

 ders, sallenders, wounds, burns, saddle galls, itchy tail (and other 

 forms of pruritis), inflammation of the joints, including those of 

 navel ill, strains, bruises, etc. It is used externally either as a 

 liniment (1 part or more of ichthyol, and 2 parts each of spirit 

 or ether and water), or as an ointment (1 part of ichthyol to 

 from 2 to 10 parts of lanoline, vaseline or oil). The hair of the 

 part should be clipped off, and the liniment or ointment rubbed in 

 twice a day. Internally it has been successfully employed in cases 

 of purpura and septic pneumonia, by intratracheal injections of 

 about 1 oz., or Z^ oz. by the mouth. 



Indian Hemp ( Cannabis Indka) 



is a very valuable soother of pain, and may be used in doses of 

 ;! to f oz. of the extract for colic, and also for tetanus. In 

 such cases, it acts far better than opium ; because its effect lasts 

 longer, and does not produce so much constipation, or such dis- 

 tressing head symptoms. The present preparations, such as the 

 extract, are liable to deteriorate by keeping, and are not of 

 uniform strength. These objections will no doubt be rectified 

 in the near future by the employment of its active principle. 



Iodine. 



For its action in " Diabetes," see p. 516.
