Cassia essential oil is a rich, spicy oil extracted from the bark of the cassia tree (Cinnamomum cassia). Closely related to cinnamon, cassia is known for its warm, sweet, and intensely aromatic fragrance that makes it a popular ingredient in aromatherapy, seasonal diffuser blends, natural home fragrances, and wellness routines.
With its comforting scent and warming aroma, cassia essential oil is often used to create cozy environments and enhance aromatherapy experiences throughout the year.
What Is Cassia Essential Oil?
Cassia essential oil is produced through steam distillation of the bark, leaves, and twigs of the cassia tree. Native to China and other parts of Asia, cassia has been valued for centuries in traditional herbal and aromatic practices.
The oil possesses a stronger and sweeter aroma than true cinnamon, making it a favorite in diffuser blends and home fragrance products.
