What it is
This is an aromatic oil obtained from the fruit and seeds of Illicium verum, the star anise plant. It is used in cosmetics and sunscreens in small amounts to condition the skin and to contribute scent, owing to the plant's characteristic aroma. Star anise oil is notably high in anethole, the compound responsible for its sweet, anise-like fragrance.
Safety & warnings
As an aromatic essential-type oil rich in anethole, it can act as a fragrance and may cause sensitivity or irritation in fragrance-sensitive individuals, so patch testing is reasonable. It should be the true star anise (Illicium verum), not the toxic Japanese star anise (Illicium anisatum).
Origin & sourcing
Natural; an oil derived from the fruit and seeds of the star anise plant, Illicium verum.
