Essential Oils (EFAs) are simply ‘essential’. We must consume them or we will not survive. Today's food supply (supermarket stuff) is out of balance; the oils that are on the shelf are not correct for optimal health. There is usually little to no omega 3. Or, there is too much omega 3, such as found in plain flax oil. Quite simply, we need enough fatty acids, in the right balance, for the human body to function consistently & properly. The correct ratio has been thoroughly researched by scientists and is 4:1 (4 parts of omega 6, linoleic acid, to 1 part of omega 3, linolenic acid).
