The silver powder,

1. It is a natural antibiotic that does not have any side effects. Silver not only sterilizes all harmful bacteria, but also completely absorbs and blocks harmful wavelengths such as electromagnetic waves and water waves. In particular, silver powder has a strong power to sterilize about 650 bacteria and almost all single cell pathogens on the ground, including fungi and virus, within 6 minutes.

2. It also has an excellent effect on the improvement of human immunity. That is, silver activates human cells because nano-sized colloidal silver particles (3-20 nm) penetrate into the nucleus of cells with oxygen adsorbed from the surroundings and promote cell oxygen metabolism. On the other hand, silver particles have been found to effectively remove free radicals around cell membranes.

3. Detoxification and odor removal effect. In addition, it is also effective in disinfecting various bacteria that are the source of odors or by neutralizing by-products ammonia and denatured proteins to remove various odors.

The charcoal powder,

1. Charcoal has an effect of increasing negative ions. In other words, negative ions affect the parasympathetic nerve to stabilize mood and relax body tension.

2. Far-infrared radiation effect, far-infrared light is called the light of life and has the effect of promoting blood circulation, promoting metabolism, activating cellular function, promoting growth, activating and aging of water molecules.

3. It has electromagnetic wave blocking and air purification effect. In other words, charcoal has excellent adsorption, electrical conductivity, and electrical storage capacity, and therefore, when placed on the back or side of a home appliance such as a computer or a TV, it can block or absorb electromagnetic waves.

In addition, it is a porous microbial habitat, particularly because the "decomposable actinomycetes of organic matters live well", so it adsorbs and decomposes polluted components or harmful impurities in the air to purify the air and remove odors.

4. Purification and Purification Deodorization Charcoal absorbs large amounts of moisture, such as sweat from sleeping or urine in children, to decompose impurities.

In addition, abundant minerals purify the water and purify the water by making the water particles smaller.

5. Antibacterial and detoxification effect Moisturizing Charcoal absorbs moisture when it is humid and releases moisture when it is dry, which naturally controls the humidity in the living room.

6. House dust mite removal effect House dust mites, which are toxic allergens, can be removed using charcoal.

7. Skin disease treatment effect "Because it acts as a skin cell activating effect, atopic dermatitis, senile dry dermatitis, chronic eczema, scabies and other skin diseases, incurable diseases and athlete's foot athletes and various skin diseases have been researched and its efficacy is also revealed.
