Description: Theobromine, also known as xantheose, is a bitter alkaloid of the cacao plant. It is found in chocolate, as well as in a number of other foods, including the leaves of the tea plant, and the kola (or cola) nut. It is classified as a xanthine alkaloid, which also include the similar compounds theophylline and caffeine. The compounds differ in their degree of methylation. In modern medicine, theobromine is used as a vasodilator (a blood vessel widener), a diuretic (urination aid), and heart stimulant. Theobromine increases urine production. Because of this diuretic effect, and its ability to dilate blood vessels, theobromine has been used to treat high blood pressure.
