 usually combined with one or two grains of calomel, or with 

 twenty grains of jalap. Rhubarb is used in powder, in- 

 fusion, syrup, and tincture. The compound powder, or 

 Gregory's mixture, prepared by mixing thoroughly six parts 

 magnesia, one part ginger, and two parts rhubarb all in 

 fine powder is an excellent stomachic and antacid, and is 

 given in doses twice as large as those of the simple rhubarb. 

 In diarrhoea in calves and foals it exerts carminative, 

 laxative, and subsequently astringent effects. When the 

 bowels are persistently relaxed, two drachms each of 

 rhubarb and magnesia, with half a drachm of opium, may 

 be given night and morning in well-boiled wheat-flour 

 gruel, with one or two tablespoonfuls of brandy or sweet 

 spirit of nitre. One-third to one-half this quantity is 

 prescribed for diarrhoea in lambs. 



Syrupus Rhei is made with two parts each of rhubarb and 

 coriander, twenty-four of sugar, eight of alcohol (90 per 

 cent.), and twenty-four of water ; and the compound 

 tincture with two parts of rhubarb, one-fourth part each 

 of coriander and cardamoms, two of glycerin, and eighteen
