Introduction Cassia essential oil, distilled from the bark of the Cinnamomum cassia tree, is a spicy, warm, and intensely aromatic oil closely related to cinnamon. Known since ancient times in Chinese and Ayurvedic medicine, cassia has been prized for its stimulating, protective, and comforting qualities . Its aroma is richer, hotter, and more pungent than true cinnamon ( Cinnamomum verum ), making it both powerful and distinctive in perfumery and wellness. At Herbsmetics, we introduce Cassia oil in our Perfume & Aromatherapy Workshops in Phuket , where guests explore its bold, exotic spice character and learn how even a drop can transform a blend.

Diffuser : Add 1–2 drops with sweet orange or clove for festive, warming blends.
Massage Oils : Highly diluted (very low %) for warming and circulation blends.
