In a dropper bottle we use it in the bath, in the diffuser, as a solvent to remove adhesives and the like and between our dog's shoulder blades to keep fleas and ticks at bay. In a roll-on bottle we use it to treat bites, stings & burns and to aid healing, on our upper lips at bedtime to help us sleep, on the temples to reduce tension headaches, on exposed skin as an insect repellant or simply as a delicate perfume. All that from 1 single ingredient, lavender essential oil. Plants are amazing!
