Ilex paraguariensis
Select sizeThe plant
Yerba mate is an evergreen holly-family tree. Its leaves are dried for traditional drinks.
What's in it
Caffeine is a natural stimulant that helps increase alertness. Theobromine is a related compound; polyphenols are other naturally occurring plant substances.
Caffeine
Around one per cent of the dried leaf.
Theobromine
The cocoa compound, present in meaningful amounts.
Chlorogenic acids
Abundant polyphenols, also prominent in coffee.
Saponins
Responsible for the foam that forms on a well-made mate.
How it works
Alertness: Caffeine temporarily blocks adenosine signals in the brain. Adenosine is a messenger involved in feeling sleepy. Everyday ritual: This explains why mate is enjoyed when people want to feel more awake. Its distinctive bitter-green flavour makes it a traditional alternative to tea or coffee.
In the tradition
Traditionally shared in South America from a gourd through a filtered straw.
The filtered drinking straw is called a bombilla.
