The Australian Tiwi people knew about the properties of Blue Cypress bark resins for thousands of years, and they used it to protect their skin from the harsh desert climate as well as for stomach upsets. It is now grown in plantations, and is valued for its fragrant wood which is also resistant to termites. In aromatherapy circles, the oil is sometimes referred to as the ABC Essential Oil – for 'Australian Blue Cypress'
