This glorious blood red oil is rich and healing. St. John's wort oil is used for bruises, scars, sciatica and sunbun (try combining it with a few drops of lavender and German chamomile essential oils), and is often used by herbalists to help speed healing of wounds and sores. St. John's wort oil helps to reduce inflammation, and is especially soothing to inflamed nerves. Externally it is applied to bruises, sprains, minor burns, skin irritations, muscular pain, scar tissue or any laceration accompanied by severed nerve tissue. This is not a new herbal treatment, but one that has been handed down for hundreds of years.
