Cassia is considered one of the 50 fundamental herbs in traditional Chinese medicine (TCM). It’s an evergreen tree native to China and Burma. Cassia is commonly known as Chinese cinnamon, and its scientific name is Cinnamomum cassia. Cassia essential oil, or cassia bark oil, is derived by steam distillation of the cassia bark, leaves and twigs.
Cassia is similar to true cinnamon (sometimes called Ceylon cinnamon) and mimics some cinnamon benefits and uses. They’re from the same botanical family, and they both have a spicy, warm aroma — but cassia bark oil is sweeter than cinnamon.
Cassia has been used extensively in indigenous and folklore medicine systems. In the Indian system of medicine, know as Ayurveda, the plant has been documented as thermogenic, purgative, expectorant and diuretic, and it’s been used in the treatment of leprosy, erysipelas, ulcer symptoms, cough, flatulence, dyspepsia, menstrual problems and tuberculosis. It’s also been used as a bronchitis natural remedy, anemia natural treatment and for natural constipation relief.
