Sourced from the far north coast of New South Wales, Australia, Aura Cacia's tea tree oil is as "green" as can be. Our grower focuses on soil nutrition management in order to enhance the tea tree oil production. Although at a premium price, organic materials rather than synthetic nutrition sources have been given a priority. The intention has been to ensure that soil carbon levels are maintained rather than depleted, as is often the case. The use of vermiculture and compositing has been investigated over a long period to determine the best applications for sustained production. Essential oil is obtained by steam distillation of the leaves and branch tips.
