 its chief use is in acute rheumatism, for which it is a very good 

 remedy; as a diaphoretic is used in large doses. 



ACIDUM SAUCYUCUM— SALICYLIC ACID. 



This is an organic acid, existing naturally in various plants, 

 but most largely prepared synthetically from carbolic acid, occurs 

 in needle-shaped crystals, soluble in alcohol, ether and hot water ; 

 borax increases its solubility.
