Side effects of emu oil are unknown, and there is little scientific information available, according to WebMD. Emu oil users have not reported any negative reactions when using it, according to Drugs.com. For hundreds of years, the Australian Aborigines have collected and used emu oil.
Processors take oil from the fat of the emu, a small ostrich-like bird, to produce medications, explains WebMD. Clinical studies of humans show that using emu oil on burns lessens scar formation, and using it on wounds improves healing substantially, notes Drugs.com. Animal studies show that using the oil topically produces inflammation-reducing results that are equivalent to taking oral doses of ibuprofen.
