It’s is a tisane (herbal tea) made using the leaves of the coca plant; typically the raw leaves of the plant. It is made either by submerging the coca leaf or dipping a tea bag in hot water. The tea originates from the Andes mountain range, particularly Bolivia, Equador and Peru.
The leaves of the coca plant contain several alkaloids including cocaine; in fact, they comprise the sources for cocaine’s chemical production, though the amount of cocaine in the leaves is so small, around 0.4%, that in order to make a gram of cocaine, 250 grams of coca leaves would be needed. A cup of coca tea prepared from one gram of coca leaves contains approximately 4.21 mg of cocaine.
