The mineral composition of black tourmaline shows that it is a silicate of boron and aluminum with high concentrations of ferrous iron and hydrogen. It also contains calcium, magnesium, manganese, sodium, potassium, lithium, hydroxyl and fluorine. Because of its electrical properties, it is used for frequency control in shortwave radio apparatus and pressure gauges.
Tourmaline is both pyroelectric and piezoelectric. If a specimen is put under a pressure or temperature change, it will generate an electrical charge. When this happens, dust particles become attached to the crystal ends.
Tourmaline is distinguished by its three-sided prisms; no other common mineral has three sides. Prisms faces often have heavy vertical striations that produce a rounded triangular effect.
From a lecture on stone medicine by Dr. Jeffrey Yuen, a renown Taoist priest and master of classical Chinese medicine.
Black tourmaline is known to assist the body in getting rid of radiation and heavy metals. A powerful chelation stone, it’s said to draw toxins out of the bones, as well as pull out whatever damages the DNA, i.e., cancer, radiation, mercury poisoning, HIV, chronic fatigue–all manifestations of “pestilent qi”. Tourmaline directs energy away from the DNA and helps the body to contain cellular damage.
Black Tourmaline is known as a Guard Dog Stone that can protect you either physically, mentally, emotionally or spiritually.  They ‘guard’ you energetically.   It might be from physical danger, such as when a person is a firefighter, in the military during a war, or a police officer. 
This is a huge difference between black tourmaline and other guard dog stones.  It receives the negative or heavy energy, reverses it/transmutes it through it’s piezo and pyroelectric abilities, and then sends it back to the sender!  When there is danger or perceived danger, black tourmaline will absorb it and transmute it, leaving you untouched.  It is a feminine and masculine energy and what is termed “androgynous” because it will rebalance on either side of the body as well as any field in your aura, as well as protect your chakras.
