We cannot verify that the Tunisian Patchouli is 100% essential oil, however it has a lovely aroma that would be appropriate for wearing or in a diffuser. Do not use for therapuetic purposes. We’ve sold this oil for a long time. I was hesitant in including it under Essential Oils as I am dubious to it’s purity. It is much sweeter with a powdery overtone. The egyptian supplier doesn’t speak good english and cannot verify it’s CofA. BUT, I list it here for nostaglia and there are customers who have grown to love it. However, it is not the familiar tone of Patchouli. Personally, I think it has orris root in it. So, here it is.
