Eupatorium gayanum Wedd.

Aristeguietia gayana, or asmachilca, is a bush that grows up to 1 meter in height.

It grows in the west-facing mountainsides and interandean valleys between 3600–4000 meters in altitude.

It was traditionally used by the Incas for respiratory system complaints.

[citation needed] Today, it is used in cooking, but tea is the most common preparation.
