Medical stone and bian stone are used differently. Bian Shi is a method of external treatment, which can be made into various instruments to act on human meridians and acupoints to achieve health care. Medical stone is also a beneficial stone, which can be used as medicine. In addition, Bian Shi is not only rich in dozens of trace elements and minerals, but also has special energy fields such as infrared waves and ultrasonic waves, so Bian Shi mattresses are often used for clinical treatment and health care.
