My 5 year old picked up a splinter in her big toe.
My botany kit has some tweezers, a sharp knife, and a light on one of the tiny microscopes.
My essential oils travel kit has clove oil. A good topical anesthetic and antibacterial.
A dab of clove oil, a bit of digging around with the razer knife, and a pluck of the tweezers. No more splinter.
A look at the splinter, an explanation of the oil used, a wiff of lavender. A happy little girl.
