At Herbs of Avalon, we use all organic herbs, essential oils, oils, beeswax, etc.! Our products contain nothing that isn't listed as an ingredient and preservation of products is from natural substances....For instance, did you know that Vitamin E is a preservative? Or that Grapefruit Seed Extract has antibacterial properties? There are no harsh ingredients used in any of our products, such as chemicals, dyes, or sulfates.Our skin is the largest organ and our first line of defense against pollutants, so why would you want to put anything ON your skin that you wouldn't put UNDER it? When you put products on the surface that contain harsh chemicals those chemicals end up in your body.
