Cassia Oil

Cinnamomum cassia


A warming oil that dates back to biblical times, Cassia essential oil may promote healthy digestion and immune function while providing a strong, uplifting aroma.*



A close relative to Cinnamon, Cassia has a strong, spicy aroma that can be used in small quantities to transform any essential oil blend. Cassia has been used for thousands of years for its many health benefits. It’s one of the few essential oils mentioned in the Old Testament, noted for its welcome, unmistakable fragrance and calming aromatic properties. Preclinical studies suggest that cinamaldehyde, a main chemical component of Cassia oil, may support a healthy immune response, digestive system, metabolism, and cardiovascular system, but more confirming clinical research is needed.† Cassia is an ideal oil to diffuse during cold months due to its warming properties and spicy scent.Because of its potential to irritate the skin, Cassia should be dilut ed with a carrier oil when applied to the skin and can be very strong when inhaled directly. When diluted and applied topically, Cassia can help soothe the skin. Cassia can be used in cooking either as a replacement for Cinnamon in pies and breads or by itself in a myriad of entrées and desserts.
