CALUMBA 53i 



strong, aromatic, somewhat musk-like odor; its taste is 

 warm and very bitter. 



Gonstit'uenis. — 1, cascarillin, a neutral, bitter, crystalline 

 body; 2, two resins, 15 per cent.; 3, a volatile oil, 1.5 per 

 cent.; 4, tannic acid ; 5, gum. 



Incompatihles. — Metallic salts, mineral acids, and lime 

 water. 



Dose.—R &C.,l ss.-i. (15.-30.) ; Sh. & Sw., 3 i--ii. (4.-8.); 

 D., gr.x.-xxx. (.6-2.), 



Administration. — Cascarilla may be given in powder to 

 the larger animals on their food, or in infusion (1-10, B.P.), 

 or tincture (1-8, B.P.), ^ iv.-vi. of either for horses ; 3 ss.-i. of 

 the tincture for dogs. The infusion does not keep. 



Action and Uses. — Cascarilla is called an aromatic bitter, 

 since it combines the action of a volatile oil in stimulating 

 gastro-intestinal secretion, motion, and vascularity, with that 

 of the bitters in exciting the appetite, gastric and salivary 

 secretions, together with vascularity and peristalsis of the 

 stomach. The drug is suitable for the same cases as gen- 

 tian, but is particularly indicated in the treatment of atonic 

 gastro-intestinal indigestion with flatulence (on account of 

 its volatile oil). Mineral acids precipitate the resins in 

 tinctures, so that the infusion may be combined with the 

 former.
