The term 'Andean Stimulants' refers to a variety of traditional South American beverages made from coca leaves, which are native to the Andes region. The most popular of these drinks is coca tea, which is made by steeping the leaves in hot water. Cocas, a type of fermented beverage made from coca leaves, is also popular in the Andes region. It is made by mixing the leaves with sugar and other ingredients, and then allowing it to ferment for several days. Both coca tea and cocas are known for their energizing effects, and are often used as stimulants by people living in the Andes region.
