Bamboo charcoal turns the bath water into alkaline water to soften the water, and the heat effect from far-infrared radiation makes it less cold after bathing and improves blood circulation. Especially, it contains twice as much minerals as charcoal to protect the skin. The effect is also excellent.

This can be clearly seen by comparing the mineral content of bamboo charcoal. Bamboo charcoal has a content of 0.39 calcium, 1.04 potassium and sodium, and 1.60 silicon, whereas nonchocoal has a content of 0.63 calcium, 0.34 potassium and sodium, and 0.01 silicon. It has been identified that there is a large difference in mineral content.

Bamboo charcoal is also excellent in electrical conductivity and has excellent electromagnetic wave shielding effect to prevent the occurrence of static electricity. When bamboo charcoal is manufactured at 600℃, the shielding effect (DB) is 0-5, indicating a shielding rate of 68.4%. When manufactured at 800℃, the shielding effect (DB) is 10 to 37, which represents a shielding rate of 90.0 to 99.9%, and if bamboo charcoal is manufactured at 1,000 °C, the shielding effect (DB) is 50 to 70, which is 99.99% shielding. You will be able to.

In addition, bamboo charcoal absorbs a large amount of water, such as sweat and urine during sleep, to decompose impurities in an instant. Also, the rich minerals purify the quality of the water and reduce the water particles to change tap water into delicious mineral water. And water purification effect.

In addition, bamboo charcoal is made at an ultra-high temperature of 1,000℃ and is homogeneous. Also, by adding bamboo vinegar liquid with sterilizing power, it can inhibit bacterial growth and double its antibacterial activity, and its far-infrared radiation rate is very high. It can have health-promoting effects that promote circulation and metabolism.
