These tubes contain the second wash from a batch of RSO material. The solvent is 95% ethanol (everclear). There was an ounce of Blueberry Blast along with homegrown mongrel flowers in the extract jar so the tincture smells like fruit. I use this stuff for scratches, cuts, aftershave, and itchy patches of skin. The lighter tubes soaked for 24 hours, the darker tubes for over two weeks. On the skin the alcohol evaporates and leaves a layer of plant waxes and oils but it isn't sticky, more membrane-like, it stops minor bleeding by sealing itself.
