How do I safely add this lemongrass oil to a bath?

Essential oils, including this lemongrass oil, do not mix with water on their own. Adding it directly to a bath can cause the concentrated oil to float on the surface and come into direct contact with your skin, potentially causing irritation. For a safer, more enjoyable experience, mix 3-5 drops of the oil with a small amount of a carrier substance before adding it to the bathwater. A neutral carrier oil like sweet almond or jojoba works well, as does a tablespoon of full-fat milk or an unscented bath gel base. This disperses the essential oil throughout the water. It's also sensible to enter the bath after the water has been poured to avoid inhaling the initial, strong vapor. Always start with a lower number of drops to test your skin's reaction.
