An emu is a flightless bird, scientifically named Dromaius novaehallandiae.
The bird is native to Australia, but is now found in many countries, because of a rising popularity of nutritious emu meat and medicinal emu oil.
Emu oil is a bright yellow liquid, made up of mostly fat, which is collected from the deposits below the skin of the bird.
Once the fats are collected, they are passed through various filters and processes until pure oil is produced. The different types of emu oil depend on the different levels of filtration and processing.
Most emu oils will go through full processing in order to reduce bacteria and contaminants. Some emu oils are refined more than others, in order to create higher contents of fatty acids.
