This makes them very useful in a practitioner/client relationship. Herkimers are calming stones and can bring clarity of mind. They are extremely useful in helping you to recall your dreams. They enhance creativity and are very useful in releasing energy blockages when placed between Chakra points. They also help to relieve stress and tension.
