There have been some threads on here about green EO blends (grass, tea..) and one ingredient that keeps coming back is clary sage. Unfortunately it's outside of the price range of EO's I'd be willing to use for soap. Is there an alternative? Dalmatian and Spanish sage are both 1/3-1/2 of the price of clary sage, but seem to be described as more herbal than fresh, but I've never smelled any of them. Does anyone have experience with them and can tell me the difference between clary/dalmatian/spanish sage and if they could serve in a 'green' EO blend?
