Cassia is a medium-sized deciduous or semi-deciduous tree that grows up to 10–15 m in height. It blooms from May to July and produces lightly scented yellow flowers. Temperatures in the range of 19to 25 oC are ideal for cassia growth. The tree requires annual rainfall between 650 and 2400 mm. Cassia is resilient and can survive drought-like conditions. It, however, requires full sunlight to survive. Cassia oil is extracted via steam distillation from the bark of Cinnamomum cassia. The oil extracted is a dark brown, free-flowing liquid with a strong and spicy odour. There is limited stock on the market. Oil distillation from the new crop is expected to commence soon.
