Cacao (Theobroma cacao)

Cacao Overview:

Theobroma cacao is the tree that gives us chocolate. It's seeds are roasted, crushed, and mixed into water to form a thick, bitter brew. Which was traditionally used in South America as a stimulant and aphrodisiac.

Some of the chemicals contained in the seeds are closely related to caffeine. Theobromine, which is the main active constituent in cacao, is nearly identical to caffeine in fact. It has very similar effects overall to caffeine, but is a weaker mental stimulant, and a stronger broncodilator and vasodilator. This makes theobroma useful for athletic performance, as it increases the airflow to the lungs, combats high blood pressure, and provides subtle mental stimulation.

The medicinal uses of Theobroma cacao vary significantly depending on the plant part used.
