What is Yerba Mate?

Mate is a plant. The leaves are used to make medicine.

Mate is used as a stimulant to relieve mental and physical tiredness (fatigue), as well as chronic fatigue syndrome (CFS). It is also used for heart-related complaints including heart failure, irregular heartbeat, and low blood pressure.

Some people use mate to improve mood and depression; to relieve headache and joint pains; to treat urinary tract infections (UTIs), and bladder and kidney stones; for weight loss; and as a laxative.

In foods, mate is used to make a tea-like beverage, known as maté or Yerba Maté, which is very popular in Brazil, Paraguay, and Argentina.

  • Diabetes. Early research suggests that drinking yerba mate tea three times daily for 60 days can lower blood sugar in people with diabetes.
  • High lipid (fat) levels in the blood.
