Tourmaline
Tourmaline emits far infrared radiation in the 4-14 micron wavelength -- an electromagnetic range which is known to bolster the immune system and enable detoxification. Tourmaline is highly beneficial for stimulating the body's natural purification processes. It produces the same resonance as water, allowing for absorption that helps combat fatigue, increase alertness, and improve circulation. Ultimately, tourmaline provides essential support to the immune system.
