Tourmaline is an energy gem, which has the characteristic of permanently emitting far infrared rays. Cerebrovascular protector is used to dredge the whole body meridians, dilate capillaries and promote the whole body qi and blood circulation.

Tourmaline spar has strong energy, and gemstone energy can be converted into blood circulation with temperature. It is good for people with deficiency of both qi and blood, weak body and cold hands and feet.

Tourmaline is worn for a long time, so it is safe to sleep slowly, which will have some subtle effects on the body. I hope my answer is useful to you.
