St. John's wort oil can be used to restore skin for minor superficial wounds, abrasions, or irritated skin after sun exposure. It is a very old traditional medicine that supports blood circulation and alleviates water retention. St. John's wort oil can cause photosensitization reactions. Do not expose the treated skin to strong light, sun or solarium (for 24 hours after use). How to use: As a massage or cosmetic oil for facial and body use. Pure or with Physalis essential oils. This oil is also used for food purposes.
