      diuretic drug and major alkaloidal constituent of cocoa. Theobromine is a xanthine alkaloid, a methylxanthine, as are caffeine and theophylline, but it differs from them in having little stimulatory action upon the central nervous system. The stimulant effect of cocoa results from the caffeine that it contains rather than from the theobromine.
