Black Tourmaline is a premier stone for purification, protection and repelling negative energy. It increases vitality and emotional stability and is incredible for aiding the user in creating a grounding circuit with the earth's electromagnetic field.
Black tourmaline has been used since ancient times by Shamans and healers for its protection properties. It is considered by many to be the most powerful protective stone and it is one of the only stones that protects and heals physically, emotionally, mentally and spiritually.
This stone helps to put an energetic boundary between you and others so that you don't pick up anything that's unwanted. When placed in the corners of the room, (or even embedded in the walls) it seals in the room with a protective shield.
It is also used to activate grounding between the base chakra and the center of the Earth. It provides further enhancement of ones well being on the physical plane and protects against those in the spirit world who are not in the "light" and do not understand the love of the universe.
It acts to stimulate the reflex points associated with the lower back. Black Tourmaline has been used in the treatment of arthritis, dyslexia, heart disease, anxiety and disorientation
