Bianstone Block small size of dimension of about 12 x 7.5 x 2 cm, weighing about 1 kgs, can be heated by hot water, hot air, or simply by exposing it to sunlight. After being heated, it can be applied to the waist, the back and any part of the body for quick relief of pain, or simply stimulating the acupressure point for healing purposes.
It is also a very good stone for sensing (due to its very long far infrared and other properties). You can also use it for sleeping, or place it under your body or head when you sleep for remote infrared sensing.
Or you can step with both legs on the warm bianstone block for foot reflexology to stimulate the blood flow as well as stimulating the foot acupressure points for healing purposes.
