Rich in antioxidants, polyphenols, and methylxanthines, yerba mate exhibits various pharmacological activities, including anti-inflammatory, cardioprotective, and anti-diabetic properties. Its stimulating effects, attributed to caffeine, enhance mental alertness and physical performance, making it popular among athletes. The processing methods of yerba mate, including harvesting, roasting, and maturation, significantly influence its flavor and health benefits. Despite its long-standing cultural significance, scientific research on yerba mate has intensified in recent years, revealing its potential as a functional food ingredient.
