Tourmaline is a semi-precious mineral stone well known for its incredible ability to aid in the detoxification process of the human body. It is one of only a handful of minerals that have the ability to emit negative ions and far-infrared rays.
Tourmaline produces a detoxifying, cleansing effect on the nervous system, as well as the organs and tissues of the body. It has been shown as a useful aid for improving circulation, reducing stress, improving brain alertness and activating the immune system. It has a highly stabilizing effect on our nerves, due to its capacity to generate its own heat. This ability to self-produce an electrical change makes it one of the only minerals that can emit far infrared heat, as well as negative ions. 
Titanium ION Bracelets release negative ions from multiple sources, to provide the maximum benefit and protection to your body.
