The Irises from the family Iridaceae are found in Europe, North Africa, Eastern Asia, the US and Russia. In skin care products, it has an anti-inflammatory effect but also has strong general skincare properties.
In aromatherapy, Iris has a slightly numbing, liberating and highly inspiring effect. It counteracts mental stress and closes holes in the aura. In small doses, Iris oil is excellent for meditation.
