Stone in Sishui, Shandong Province, Chinese medicine believes that top-grade stone has the functions of calming nerves, regulating qi and blood and dredging meridians. It is the top grade stone for processing medical devices (mainly used to make scraping plates, hammers, anvils, etc.). Recently, it has been processed into various ornaments, but it still belongs to the category of Chinese medicine health care, not pure ornaments or jewelry). Through the induction of friction heating, the pulse becomes a wave pattern, and the stone is not only used as a simple scraping tool. Before ironmaking, the ancients relied on hammers to treat the pain and diseases of injured stone bracelets. In ancient times, there were medical tools such as needles and knives. By modern medical means, Spin Bian Shi can emit a variety of far-infrared and ultrasonic pulses beneficial to human body, promote blood microcirculation and regulate metabolism, which is equivalent to far-infrared therapeutic instrument+ultrasonic therapeutic instrument. Because it is impossible to tell whether it is top-grade stone only by color or appearance, wearing or using stone with unknown composition without the approval of the state may not be effective, and it may also be harmful to the health!
