 Spain, to compete with the tea that England sold, put a chopped yerba mate on sale to make tea that became popular in Europe, known as the "Tea of the Jesuits".That "Tea of the Jesuits" from the 17th century, today has become the "mate cocido", a very popular infusion that, because of the low price of yerba mate compared to the price of tea or coffee, has become since the early 20th century the common beverage in schools, hospitals and prisons.The preparation of "mate cocido" in tea bags is almost the same as regular yerba mate, with the difference that in grinding the dust and sticks are removed, sorting and processing only the leaves.
