Herkimer Diamond Palo Santo Herkimer Diamond is one of the strongest crystals for clearing electromagnetic pollution or radioactivity, blocking geopathic stress, and for the restoration of equilibrium. Herkimer Diamond, with its pure, crystal light, clears the chakras, opening channels for spiritual energy to flow. It stimulates conscious attunement to the highest level, and is particularly helpful in activating and opening the Crown and Third Eye Chakras. Palo Santo is traditionally used as a natural remedy for colds and flu, as well as symptoms of stress. It is also known to relieve asthma, headaches, anxiety, depression, and reduce inflammation. As an essential oil, it's great for aromatherapy and can also be used during therapeutic massages.
