STRONG OILS 100% PURE BIRCH TAR ESSENTIAL OIL 10 ML (1/3 OZ) THERAPEUTIC GRADE

This is a great oil, but very strong. You will need to dilute it A LOT. It smells like smoke. I bought it to blend with a tobacco absolute to give it a slight smoky smell. My first experiment was one drop undiluted with a blend I already like and it smelled like a campfire and nothing else. When it is diluted though, it adds an amazing dimension to that same blend.
