Description
Cassia Essential Oil is steam-distilled from the bark of Cinnamomum cassia, an evergreen tree native to Southeast Asia. With its bold, cinnamon-like spice, this oil brings deep warmth and richness to blends. Often diffused, it creates a cozy atmosphere, while diluted topical applications offer a stimulating effect. It harmonizes beautifully with citrus, clove, and vanilla oils, making it a favorite in aromatic compositions, seasonal fragrances, and massage applications. Its inviting nature keeps it a valued oil.
