Armoise oil is distilled from dried Artemisia vulgaris herb, which is also known as mugwort. The plant has a reddish stem, clusters of small white flowers and hairy green leaves. There are around 300 species in the Artemisia genus.
They grow wild around northern temperate regions, South Africa and South America. Artemisias are also popular as ornamental plants and some species are favoured in flower arrangements for their freshly fragrant leaves.
