Overview:Maté, also known as yerba maté, kali chaye, and Paraguay tea, is a small evergreen tree or bush native to Brazil, Argentina, and Paraguay. In most parts of South America, maté is the national drink, and as a daily stimulant, it is even more popular than tea or coffee. Maté tea, which is made from the dried, crushed, or powdered leaves, acts on the central nervous system as a stimulant, diuretic, and mild pain reliever. These medicinal properties can most definitely be attributed to the high caffeine content in the drug. Like other herbs that contain caffeine, Maté is used for fatigue, water retention, gastrointestinal complaints, and as a wakefulness promoting agent. Studies are being conducted to see if Maté can be used as an effective treatment for obesity. Maté is not recommended for prolonged or habitual use. As a metabolic stimulant, yerba mate has shown positive results in clinical studies of obesity.
Traditional Use/Benefits/Body Systems:Stimulant to alleviate mental and physical fatigue; source of antioxidants, diuretic for the urinary system.
