Theobromine, the alkaloid contained in the beans, resembles caffeine in its action, but its effect on the central nervous system is less powerful. Its action on muscle, the kidneys and the heart is more pronounced. It is used principally for its diuretic effect due to stimulation of the renal epithelium; it is especially useful when there is an accumulation of fluid in the body resulting from cardiac failure, when it is often given with digitalis to relieve dilatation. It is also employed in high blood pressure as it dilates the blood-vessels. It is best administered in powders or cachets.

Brew a strong infusion of this seed powder by taking two tablespoons and working it into one cup of cold water. Start this heating slowly and gently, gradually bringing it to the verge of boiling.
