Where do yerba mate leaves come from?
Coming from a yerba mate tree or Ilex paraguariensis, mate leaves come straight from Argentina, Brazil and Uruguay (South America). Mate is prepared from dried and roasted leaves.
This traditional drink offers an intense taste with a touch of bitterness very appreciated by Native Americans. You recognize it by its greenish color.
Argentina is the largest producer and exporter of mate. It was coveted at the beginning of the 20th century, notably by Swiss intellectuals who thought that mate would become a global drink, like coffee. Today, mate is an essential drink in this region of the globe because of its medicinal virtues.
This plant, known for its energizing and antioxidant properties, is increasingly consumed throughout the world. However, like any drink containing stimulating substances, it is important to respect a recommended daily dose.
What are the side effects of mate on health?
Studies have shown that yerba mate contains caffeine, as well as theobromine, two substances that can have side effects if consumed in excess. These effects include irritability, insomnia and palpitations, especially with increased sensitivity to caffeine.
Yerba mate leaves contain caffeine, but also theobromine present in cocoa trees. What is it for? This molecule diffuses energy constantly, unlike coffee.
The side effects that can occur due to excessive mate consumption actually come from the caffeine. In fact, a cup of mate contains 70 mg of caffeine: less than coffee, but more than tea!
What is the maximum recommended dose of caffeine consumption?
It depends on each person’s health and age. It is between 200 and 400 mg per day. Each person has a different tolerance to this molecule. Ask your doctor for advice if you have any doubts or questions.
