Té de coca

Coca tea, also called mate de coca, is a herbal tea made using the raw or dried leaves of the cocaine-containing coca plant, which is native to South America. It is made either by submerging the coca leaf or dipping a tea bag in hot water. The tea is most commonly consumed in the Andes mountain range, particularly Argentina, Bolivia, Colombia, Ecuador and especially in Peru, where it is consumed all around the country. It is greenish yellow in color and has a mild bitter flavor similar to green tea with a more organic sweetness. There is no evidence that the use of coca tea leads to dependence or addiction, potentially due to the low concentrations of cocaine present.
