KIHOSEKI, TENSHOSEKI, BLACK SILICA, etc. are often used as a ore of slabs of bedrock bathing.
The most important point to choose the stone is the wavelength of far-infrared rays.
The water molecules resonate with the light with a wavelength of 6.27 micron. Our body is constituted with about 70% water and others. So, we think this 6.27 micron far-infrared rays is the key factor. KIHOUSEKI emits this 6.27 micron far-infrared rays very strongly.
