The thing that is unique about MONTANA EMU RANCH EMU OIL is that you are guaranteed the oil you are getting is from the birds off this ranch. We are one of the few, if not the only ranch, that sends in large enough batches of fat to be guaranteed that it is not mixed with any other ranches fat from any other part of the country. This is VERY important because just like humans, Emu store toxins in their fat. The cleaner the feed and living conditions of the Emu the better the quality of the oil!
