Many essential oils may be applied directly to the skin. The wrists, thumb webs, feet, and toe webs are great areas to apply the oil. The thumb webs directly impacts the solar plexus chakra which is the location of negative emotions. Applying oils between the toes can have an impact on the spine and the overall aura (the energetic “mold” or “blueprint” that surrounds us). Do not use caustic or sensitizing oils directly on the skin.
