Sibin pumice is the earliest stone named in China. The Pian made of it (a special musical instrument, instrument and artifact of the ancient Gong royal family) is called Spence Pumice, a tribute more than 4,000 years ago, and the medical tool made of it is Pian Stone. It has the following characteristics:

(1) Spin Bian Shi has a peculiar energy field, which acts on the human body and follows the meridian, and can produce infrared heat phenomenon.

(2) Rubbing or knocking on this stone can emit extremely rich ultrasonic pulses with special frequencies.

(3) This kind of stone has no radioactivity and is harmless to human body.

(4) It contains more than forty kinds of trace elements, among which strontium content is very high.

(5) In contact with human epidermis, the improvement and acceleration of blood flow in small blood vessels and capillaries can be clearly seen in the monitor.

(6) Drinking the soaked water of Spine can reduce the triglyceride and cholesterol in the blood and increase the high-density lipoprotein, which has obvious effect on regulating blood lipid.

By modern medical means, Spinstone can emit far-infrared thermal radiation with a specific wavelength and ultrasonic pulse vibration with a specific frequency, which can act on human meridian points and plantar reflex areas, promote microcirculation and regulate metabolism, equivalent to far-infrared therapeutic instrument+ultrasonic therapeutic instrument.
