Healers of nearly every discipline have embraced the Richway Amethyst BioMat for more than twenty years. It is sometimes described as an infrared heating pad, but it’s much more than that. It uses many pounds of hot amethyst crystal to produce a unique signal of infrared light. This light is experienced as a wholesome and enveloping warmth that is both gentle and powerful at the same time. The benefits of this hot crystal therapy must be experienced to be believed.
