I have always wondered why aromatherapy was so powerful - orange is fantastic for adrenal fatigue and a mix of clary sage and balsam fir as prebiotic while introducing new bacteria (the leaks in the gut MUST be fixed BEfore you do that)
As far as oil emulsification is concerned, I would bet this is exactly what flaxseed meal does. It spreads into the guts, since it is ground and it is full of omega 3. It really works wonder - but you have to take it over a long period of time to see a difference.
