destruction of round-worms in horses. . A laxative ball may 

 be composed of aloes ( 3 ii.-iv.), ginger and powdered nux 

 vomica (each 3 iiO> mixed with glycerin or molasses. 



It is often taught that aloes is contraindicated in haemor- 

 rhoids, but this teaching does not obtain unless the piles 

 are inflamed. In piles, associated with an atonic conditiqu, 

 aloes- may be beneficial by improving the tone of the bowels. 

 Aloes may be useful in jaundice due to constipation, but in 

 general it is inferior to salines, calomel and podophyllin in 

 the treatment of this disorder. According to Brunton, the 

 presence of bile in the intestines is essential for the chola- 

 gogue action of aloes. Therefore the absence' of bile in the 

 bowels would forbid the use of aloes as a purgative. 

 Laxative doses of aloes are valuable in amenorrhoea, 

 about the time that " heat " should occur, in combination 

 with iron.
