The emu is a flightless bird that resembles a small ostrich. Emu oil is taken from the fat of this bird during processing. It is used to make medicine. Emu oil is taken by mouth for improving cholesterol levels, as a source of polyunsaturated and monounsaturated fatty acids, for weight loss, and as a cough syrup for colds, H1N1 (swine) flu, and flu. Some people apply emu oil to the skin for relief from sore muscles, aching joints, pain or inflammation, carpal tunnel syndrome, sciatica, shin splints, and gout.
The emu (Dromaius novaehollandiae) is the second-largest living bird by height, after its ratite relative, the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the genus Dromaius. The emu's range covers most of mainland Australia, but the Tasmanian emu and King Island emu subspecies became extinct after the European settlement of Australia in 1788. The bird is sufficiently common for it to be rated as a least-concern species by the International Union for Conservation of Nature.
