Plattsburgh State University of New York. Volume 5 (2011) 77 Titled ;” An ecological and cultural review of the emu (Dromaius novaehollandiae) By Carroll and Christopher T. Martine “Therapeutic properties can vary greatly depending on the diet and lifestyle of individual birds.” “The Whitehouse et al. (1998) study also produced evidence that among farmed birds, oil from those farmed in Australia had far better therapeutic properties than those farmed in North America or Europe. There is 1-2% of emu oil composition that has not been positively identified, but it is thought to contain a varying mixture of natural antioxidants and other enhancers (Lindsay 2010). The Australian birds were farmed by Aborigines, suggesting that a more natural, stress-free state (due to a unique knowledge of the emu that is not present in the west) creates a more therapeutic composition in the oil (Lindsay 2010).” Emus are native to Australia and therefore any attempts to breed from a flock of birds outside of Australia, no matter how huge, will be limited and naturally affect the quality of the oil.
