Yes, you can use this clove essential oil in a bath, but it must be properly diluted first as it should not be applied neat to the skin or added directly to bathwater, where it could cause irritation. For a full bath, mix 1 to 2 drops of the clove oil with a tablespoon of a dispersant like unscented bath gel, liquid castile soap, or a carrier oil such as jojoba or sweet almond oil. Stir this mixture thoroughly into the running water before you get in. The warm, spicy aroma will help create a relaxing atmosphere, which is why this oil is often chosen for evening use. Limit your soak to 15-20 minutes. Because clove oil is potent, using more than a couple of drops is not recommended, and you should avoid this method altogether if you have sensitive or reactive skin, are pregnant, or are new to essential oils. Always rinse off after your bath and ensure the oil is kept away from your eyes.
