Caffeine (or hot tea or coffee) lessens central de- 

 pression and may well be given to offset undesirable 

 properties of the antipyretics, especially those of 

 the coal-tar group. It is a diuretic useful in dropsy 

 and to aid in the elimination of toxic substances. 



It is useful in the heart failure of pneumonia and 

 septic infections. With phenacetin, it is employed 

 in migraine and periodic headaches. 



The dose is 2 grains; of citrated caffeine, 5 grains. 



There are several xanthine derivatives, some sur- 

 passing caffeine hi diuretic effect. THEOBROMINE 

 (5 to 8 grains) is a good diuretic in the edemas and 

 is not so apt to induce insomnia as caffeine. THEO- 

 BROMiNE-SoDiUM ACETATE (8 to 15 grains) is more 

 soluble and better tolerated by the stomach. AGURIN 

 is similar to the last-named. THEPHORIN (7% grains) 

 is also diuretic. UROPHERIN-B (5 to 15 grains) is 

 used in connection with digitalis. THEOPHYLLIN is 

 a powerful diuretic, but not lasting. It should be 

 followed by other agents (dose 3 to 5 grains). 

 THEOPHYLLIN SODIO-ACETATE is given in the same 

 dosage. See "New and Nonofficial Remedies" for 

 details. XANOL, caffeine sodio-salicylate from nat- 

 ural oil, is a vaso-motor heart tonic and diuretic 

 (2 to 5 grains). 



CAJUPUT 



The oil is official in several pharmacopeias. It 

 is derived from Melaleuca leucadendron. It con- 

 tains 60 per cent of cineol. For internal use as a 

 balsamic stimulant, the British Pharmacopeia spirit 

 may be used in doses of 5 to 20 minims. Formerly 

 the oil was used as an application to frost-bite.
