LAXATIVE PHTHLEINS 



Phenolphthaleinum — Purgen. This is an artificial anthra- 

 cene derivative, prepared by the interaction of phenol and phthalic 

 acid. It is a white crystalline powder, slightly soluble in water, 600 

 parts, and freely so in alcohol, 10 parts. It is used for the small ani- 

 mals only in doses of from "H-O to 4 or 5 grains. It is an agreeable 

 and fairly reliable purgative, producing large watery stools, and 

 appears to have no other action. Solutions in oil injected subcutane- 

 ously cause purgation without local irritation. This is the drug 

 upon which most of the candy cathartics depend for their action. 

 It may be given in pill and is sometimes combined with calomel when 

 that agent is to be given in small divided doses. 



d. THE MERCURIALS 



This group comprises the insoluble purgative mercurials, calomel 

 (mild mercurous chloride), mass of mercury (blue mass), and mer-
