Brewed from the leaves of the perennial tree Ilex paraguariensis, yerba mate is a traditional beverage in many parts of South America, including Argentina, Paraguay and Brazil. Often passed around in a gourd to be sipped socially, yerba mate tea is a vital part of these cultures. It is now available outside of South America, with growing popularity in the U.S. and other international markets. Examining the health facts of yerba mate is vital to understanding this traditional drink.
Antioxidants
Antioxidants are chemicals that work in the body to prevent free radicals --- or electrons that are literally "freed" from their source atoms --- from damaging cell DNA and energy-producing mitochondria. Yerba mate contains high amounts of antioxidants, reports the "Journal of Food Science." This cell-protecting property of yerba mate is due to its high concentration of polyphenols. Also found in plants such as green tea leaves and raspberries, polyphenols are compounds rich in antioxidants ready to help protect cells from free radicals.
Vitamins and Minerals
Yerba mate is rich in healthy vitamins and minerals, the University of Florida reports. It contains vitamins A, C, B-1 and -B2, all of which stimulate the activity of muscles and lungs. Mate also is a good source of magnesium and potassium, minerals essential for maintaining your body's energy and enhancing concentration.
Stimulant and Diuretic Properties
Yerba mate has a high caffeine content --- comparable to that of coffee --- and is popularly consumed for its stimulant effects upon the central nervous system, including increased energy and enhanced alertness. Yerba mate also has diuretic properties, reports the UC Davis Department of Plant Sciences, which also stem from its caffeine content. Diuretics increase urination and can help flush the body of toxins contained in urine. Keep in mind, however, that if you use yerba mate as a diuretic, it is vital to drink plenty of water to prevent dehydration from the herb's diuretic properties. Also, if you are sensitive to caffeine, talk to your personal physician for advice on whether yerba mate is a good option for your overall health.
Potential Health Benefits
Many potential health benefits of yerba mate are currently being researched by scientists among the medical community. Some evidence supports yerba mate's potential for preventing certain types of cancer, staving off diabetes and increasing fat metabolism to combat obesity. Although these potential health make yerba mate a singular herb to consider incorporating into your diet, additional research is needed to prove long-term health benefit cllaims.
