Emu oil is oil derived from adipose tissue harvested from certain subspecies of the emu, Dromaius novaehollandiae, a flightless bird indigenous to Australia. Unadulterated emu oil can vary widely in color and viscosity anywhere from an off-white creamy texture to a thin yellow liquid, depending on the diet of the emu and the refining method(s) used. It is composed of approximately 70% unsaturated fatty acids. The largest component is oleic acid, a monounsaturated omega-9 fatty acid. Emu oil also contains roughly 20% linoleic acid (an omega-6 fatty acid) and 1-2% linolenic acid (an omega-3 fatty acid).
