The Ilex paraguariensis, commonly known as yerba mate, is a plant native to the subtropical regions of South America, particularly Argentina, Brazil, Paraguay, and Uruguay. It is a medium-sized tree with a grayish trunk, typically reaching heights of 4 to 6 meters. Its leaves are deep green, elongated, and slightly serrated along the edges, and they are the primary component used to produce the traditional infusion. This species belongs to the Aquifoliaceae botanical family.

Since ancient times, yerba mate has been highly valued by indigenous peoples, especially the Guaraní communities, who used it both for its stimulating properties and its cultural and social significance. Over time, its consumption spread widely, and today mate is a deeply rooted tradition enjoyed by millions of people across different countries and cultures, transcending social and geographic boundaries.
