In the Andes it is known as Huacatay or Wacatay, and in other regions it is common as chinchilla, chiquilla, chilca, zuico, suico, or anisillo.[3] Other names include muster John Henry,[4] southern marigold,[5] khakibos, stinking roger,[6] wild marigold,[2] and black mint.

An herbal tea can be brewed from the leaves. An extraction of the plant, "Marigold oil", is used in the perfume, tobacco, and soft drink industry.[3]
