Indigenous to coastal rainforests of West and Central Africa, the seeds of this beautiful tree have been prized for their powerful stimulant effects. The powder contains between 1% and 3.5% caffeine (usually about 2%). Theobromine is also present in amounts just under one percent.

The effects usually are first noticed as an increase in depth of breathing accompanied by spine tingling rushes of energy which begin in the lower back and swirl up to the base of the head, climaxing with a tightening of the scalp and a feeling of the hair standing on end. It can range from a quick flash up the spine to a full-on, one-by-one opening of the chakras as a kundalini-like mobilization of vital forces rises to the crown of the head. Since the skin's pleasure receptors are especially effected, the sensation of touch becomes very pleasurable indeed. The combination of an alert, receptive state of mental stimulation with the sensation of pleasure in touch make kola a delightful experience.
