What is black silica?
Black silica is said to have been transformed over hundreds of millions of years from diatoms deposited on the ocean floor, and contains a very large amount of minerals and carbon.
It is the only natural ore produced only in Kaminokuni-cho, Hokkaido, Japan. It absorbs and stores solar energy and radiates high levels of far-infrared rays of 4-14 μm wavelength at room temperature, which are said to be essential for metabolism, growth and development of plants and animals.
The Black Silica Mat is a health mat that makes the most of the characteristics of black silica.
Just like a sunbed, it provides comfortable warmth to prevent chills* and supports the health of people and pets.
*There are individual and personal differences in the feeling of warmth.
Sinmei-ishi(Sinmei Stone)
Black silica collected in the mountains of the Shinmei district in southern Hokkaido is known by the special name of “Shinmeiseki.
Since ancient times, the Ainu people realized that the water and stones from this area had the power to heal wounds, and they revered black silica as “a stone where the power of God resides.
In the Edo period (1603-1867), black silica was sold throughout the country as a “painkiller” and was highly prized.
Even today, black silica produced in Kaminokuni-cho, Hokkaido, is designated as a legal mineral by the government, and even landowners are not allowed to mine or extract it without permission.
Only the top 30% of this rare black silica gemstone is used for the highest quality.
Far infrared rays with wavelengths of 4 to 14 μm
Black silica is a very rare ore in the world that contains graphite in quartz, and is said to have been transformed over hundreds of millions of years from diatoms that accumulated on the ocean floor.
It contains an extremely large amount of minerals and carbon, and is the only natural ore in the world that emits high levels of far-infrared radiation at room temperature in the wavelength range of 4 to 14 μm, which is said to be essential for the metabolism, growth, and development of plants and animals.
third-party clinical trial
On August 1, 2008, we conducted a third-party clinical trial of black silica, for which industry-academia collaboration had long been discussed.
[Contents of the study]
Crossover double-blind randomized comparative study of the effects on heat retention and blood flow improvement, 6 male and 6 female subjects over 65 years old (exclusion criteria: patients undergoing treatment due to illness).
[Method of the study]
After using the black silica mat for 2 hours, a 1-hour blank is followed by 2 hours of placebo mat use.
The effects of heat retention and blood flow improvement during the 2 hours of use will be measured using thermography and a blood flow meter.
[Adjunctive trial]
A 6-hour crossover randomized controlled trial was conducted with two subjects.
[Test environment room]
Room temperature: 25°C, humidity: 40%.
[Measuring instruments]
Thermography, blood flow meter (Omega Wave)
[Results of the study]
Significantly higher heat retention and blood flow improvement effects were confirmed compared to the placebo mat without black silica.
All graphs listed can be enlarged by clicking on them.
[Supplemental Experiments]
It was verified that black silica has superior heat retention properties compared to charcoal and other materials.
Black silica was verified to have higher infrared radiation than charcoal and other materials.
