In my house, essential oils are a must for their medicinal uses. The staple two are tea tree and lavender. Best healing tale: My husband caught his finger in the band saw at his work. As you can imagine, his finger was a mangled mass of meat. There was nothing to stitch together. Gross. Anyway, he applied a drop of tea tree and a drop of lavender, neat, to the wound twice daily and kept it clean, dry, and bandaged. He would air it out a bit once a day for a few minutes. It never became infected - never. It healed well with virtually no scarring.
