excerpt from book Love is in the Earth by Melody

Black tourmaline can be used to both repel and protect against negativity. It acts to protect one from being victimized by the negative energy of another. It has also been used as an energy deflector, being an excellent stone for those with potential for exposure to excessive amounts of radiation. It provides for an increase in ones physical vitality, emotional stability, and intellectual acuity, and can maintain ones "spirits" even in conditions which appear to emit the messages of "gloom and doom".
It furthers the awakening of altruism and enhances practicality in creativity. As a protective stone agaist "spells" which are cast by the negative side of another, it is a special stone to Native American Indians; black tourmaline in quartz not only dispels the "spell", but energizes the "victim" and actually increases well-being; black tourmaline used with mica, returns the "spell" to the originating source and allows one to view the sender of the negative energies.
It is also used to activate grounding between the first chakra and the center of the Earth, providing for further enhancement of ones well-being on the physical plane, and protecting against those in the spirit world and/or those on the physical plane who are not in the "light" an do not understand the love of the universe.
It acts to stimulate the reflex points associated with the lower back. It can be used in the treatment of arthritis, dyslexia, heart dis-ease, anxiety, and disorientation. It can also provide for both the stimulation and the balancing of the adrenal glands.
Vibrates to the numbers 3 and 4.
