It was the first real stimulant known in the New World outside of the South American yerba mate regions, and it came in the early 18th century -- shrouded in intrigue.

„Yerba Maté supposedly does not contain caffeine, but rather a closely related compound called "mateine" which is a similar stimulant. Mateine is not as harsh to your body and does not produce the same addictive results. Others have claimed that the chemical compound within Yerba Maté is in fact caffeine, and to think otherwise is just wishful thinking.“
