Description
Cassia essential oil, distilled from the bark of the Cinnamomum cassia tree, is a rich, sweet, and powerfully spicy oil closely related to true cinnamon (Cinnamomum verum). Native to China, it has been revered for over 2,000 years in medicine, perfumery, and sacred rites. The aroma is unmistakably warm, evoking comfort, vitality, and festive familiarity — yet more intense and penetrating than its Sri Lankan counterpart, Cinnamon Bark.
The Cinnamomum cassia tree thrives in tropical regions of Southeast Asia, where its inner bark is harvested, dried, and steam-distilled to release a golden to reddish-brown oil. The resulting essence is dominated by cinnamaldehyde, a potent compound responsible for Cassia’s fiery warmth and its renowned antimicrobial and immune-supportive properties. Its scent profile is sweet-spicy with hints of clove and amber, filling a space with energizing warmth.
Cassia has played a central role in trade, medicine, and religion since ancient times. In the Old Testament, it is listed as one of the holy anointing oils (Exodus 30:24). In ancient China, it was prized for its ability to stimulate vitality and circulation, used as both a tonic and a digestive aid. Greek and Roman physicians recommended it for strengthening the stomach and dispelling cold. The oil’s warmth and stimulating nature made it a treasured commodity in ancient trade routes alongside frankincense and myrrh.
In modern aromatherapy, Cassia essential oil is recognized as both a comforting and fortifying essence. Emotionally, it encourages courage, warmth, and joy. Physically, it supports healthy circulation and immune defense. While its intensity requires careful use, Cassia’s vibrant energy brings a sense of grounding strength and optimism — a fiery spark of renewal in the cold of life’s winters.
