agarwood co2 extracts are strange but man have I become addicted to them. There is the wonderful clean, dry wood and earth smell, a different kind of sweet earthy dampness, great longevity. It’s more like smelling a good batch of wood chips before burning them. I love these oils and when they were available, they were quite affordable probably because of all the wax and resin that extracts and increases yield (speculation). A company called Nisarga Biotech used to make a decent one. Eden botanicals resold their co2 oil but the markup was hard to swallow since I knew the wholesale price.
