Yerba mate

Yerba mate (Ilex paraguariensis Aquifoliaceae)


Other Names: Mate, Paraguayan Tea

Yerba mate, an evergreen tree native to South America, grows wild along streams and is cultivated in Brazil, Paraguay, and Argentina. Known as Jesuit tea, it was introduced to Europe by Jesuit missionaries. The tree, reaching up to 10 meters, has oval, leathery leaves similar to holly but without thorns.


Parts for Use

Leaves

  1. Harvested from December to August from trees at least 4 years old.
  2. Dried quickly over fire and chopped into small pieces.
  3. Used as green mate for beverages and stews.
  4. Commercially grown trees are pruned low to ease leaf picking.

Ingredients

Contains up to 10% phenolic acids, saponins, flavonoids, a little resin, and traces of essential oil. Caffeine and theobromine are the primary active compounds, stimulating the urinary tract and heart.


Use in Treatment

Yerba mate’s high caffeine content combats fatigue, nervous exhaustion, and lethargy while acting as a diuretic for kidney problems. Research shows caffeine boosts alertness, intellectual vigor, and metabolism by about 10%. Phenolic acids, flavonoids, and saponins enhance its energizing effects. A 1988 study indicated appetite suppression, and a 1995 study showed fat breakdown in the bloodstream, suggesting weight loss potential. A 2001 study combining yerba mate with guarana and damiana supported weight loss. Recent research suggests it may protect against arterial stiffness, reducing risks of heart and circulatory disorders. It also helps relieve headaches and rheumatism pain.


Cultivation

As a tropical tree, yerba mate requires a heated greenhouse or indoor cultivation, as it cannot tolerate temperatures below 7°C.
