Can't tell you if it is Mimosa Hostilis essential oil, but in any case i doubt it contains anything good.
Essential oils are produced by
steam distilling the crude leaves / wood / whatever and collecting the oil coming over that way. DMT is not volatile enough to pass over with steam, so even if you do have Mimosa Hostilis oil, I seriously doubt it contain any tryptamines.
But i'd love to be wrong though
