This is a very powerful, heady EO. I took a pin and put a couple of tiny dots into 2 tbsp of water, heated in a ceramic simmering potpourri. The EO is by Ascention Aromatics, and is of Evernia Prunastri. Info on the back label says the country of origin is Yugoslavia, and it is an absolute from the whole plant. It has a lot number, and I am convinced this is a wholly natural and good-quality product.
Very brown and woody. Decaying leaves, sap. Peat -- hence it reminds me of a peaty Scotch! Medicinal, rubbery, band-aids, hint of leather. Again, must stress this is a very powerful, concentrated note. It is oddly compelling, it truly seems like Nature in a bottle.
