The epithet of this species has been given both as "caruifolia" and as "carvifolia" and is based on the similarity of the leaves to those of Carum carvi Linnaeus (Apiaceae). Both forms are therefore orthographically correct, depending on whether they are based on the genus name or the species epithet, and there is no case for regarding either as an orthographical error. The protologue actually gives the spelling as "carnifolia." It seems rather likely that the "n" is an upside-down "u" and that the correct spelling should be "caruifolia."

Artemisia caruifolia contains abrotanine used in anti-inflammatory and antifebrile drugs.
