The dried leaves of the Ilex paraguariensis are more commonly known as Mate or Yerba Mate and are used to make a stimulating tea. The Yerba Mate leaves contain caffeine and similar naturally occurring compounds, so unlike many herbal teas Mate is not caffeine-free. Yerba Mate is a widely cultivated, medium sized evergreen tree that grows 4 to 8m high and is a member of the Holly family. Across the whole of South America millions of men, women and children know Mate as a simple and effective way of staying in peak condition. It is a stimulating infusion which can replace morning tea or coffee.
