Wintergreen Oil (0.5 fl oz)

The steam-distillation process really comes through in the purity—one drop on my temples cut through a tension headache fast. I use it in the vaporizer with about six drops, and the room smells like a crisp forest for hours.

The tiny 0.5 oz bottle is potent—just three drops in my vaporizer filled the room with that sharp, clean wintergreen scent and my head felt clearer in minutes. I've tried other oils that fade fast, but this steam-distilled one keeps its kick for a while.
