Cassia Essential Oil (Cinnamomum cassia) is an aromatic oil obtained from the bark of cassia, a evergreen tree in the Lauraceae family native to China and Southeast Asia. It is known for being hot, sweet, cinnamon-like, and intensely spicy with a syrupy warmth and is used in aromatic practice for cold-weather atmosphere, festive blends, and everyday wellness blends.

In traditional and modern aromatherapy, cassia oil is chosen when a blend needs adds strong warmth and spice to diffuser blends used in colder weather. Depending on the formula, it may be used in diffuser blends, diluted massage oils, or carefully balanced body-care applications. Its scent pairs especially well with oils in the spicy family as well as woods, resins, and supportive citrus notes.
