Blue Cypress (Callitris intratropica) is a tree native to Australia growing in the Northern Territory.

The tree grows freely in nature and is wild-harvested to produce the oil, under a well- managed sustainability scheme imposed by the state government. The tree itself grows anything from 10-40 metres in height and in remote parts can live up to 200 years.

Blue Cypress oil is steam distilled using modern day equipment from the chipped bark and wood of the tree. Distillation can take 5-7 days depending on the temperature and pressure but it's the inclusion of the bark which houses certain resins that gives the oil its rich blue colour.
