 The Earliest Record of ZnO - Egypt
ZnO was referred to as Calamine in ancient Egypt, which is a natural mineral Smithsonite with ZnCO3 as its main compound. Because of long history, there was no knowledge of how diseases were cured .However, this is the earliest written record of human being making use of natural zinc minerals.
Medical Treatment History of Zinc Oxide
Zinc oxide is also known as "Lu-Gan-Stone" in China , according to Ben Cao Gang Mu, a masterpiece completed in 1596 summarizing the use and functionality of a wide range of Chinese herbal medicines. Zinc oxide has been used in medical treatment for quite number of years in China, only that no proper name like zinc oxide was given. Till 1750 ~ 1850, zinc oxide and zinc sulfide were formally used in medical treatment in many developed countries in Europe, which leads to increasing study and research on zinc oxide. 
ZnO Is Made After Nano Engineering Process 
ZnO May Be Used as Foodstuff
ZnO may well be used as foodstuff. ZnO is not poisonous at all. After it goes into human body, it will decompose into zinc ions, which were proven in 1963 in medical papers as the indispensable elements for human body due to Zinc Deficiency Syndrome. Comparison of Traditional Zinc Oxide and Nano ZnO
Zinc oxide is a stable material in terms of antibacterial agent, which in nature is not poisonous. Instead of just killing the bacteria, the entire purpose is to prevent bacteria from happening in the first place, which lets bacteria have no opportunity to transform, thus saving the cost of developing new antibacterial medicine. As a result, ZnO has become one of the major forces for inorganic antibacterial agent. Furthermore, the study shows that after the process of making zinc oxide into nano particles, zinc oxide will deliver greater antibacterial power without the need for UV light as catalyst.

FIR Irradiation
Infrared with wavelength ranging between 0.75 and 1000µm accounts for 80% of the sun radiant energy; among those infrared radiant, Far-Infrared radiant (FIR) with wavelength between 6µm and 14µm accounts for the most. FIR provides all the healthy benefits of natural sunlight without any of the adverse effects of solar radiation. Moreover, according to recent bio-tech research studies, FIR with wavelength between 4µm and 14µm has significant performance to boost growth for creatures and therefore is dubbed "Light of Growth". Studies also show that FIR has stunning effects on increasing blood circulation, rejuvenating damaged cell tissues, strengthening immune system, improving metabolism, etc. Our Nano ZnO powder has been proven to have IR irradiation rate of as high as 94% on average (far above industry standard), which was tested by Industrial Technology Research Institute Energy and Resources. Therefore, our nano ZnO powder exhibits better performance compared to other materials currently used in health care, medical care and skin care products. Remarkable Deodorant Effect
After the process of shrinking ordinary particles into nano particulates ranging between 1nm and 100nm, ZnO shows outstanding deodorant effect, which is a significant discovery for the academia and industry. 
| Mechanism of Deodorization | | 1.) | The Nano ZnO from Nano-infinity is able to react with both acidic and basic materials,removing unpleasant smell by rapid reaction with ammonia molecules in the body or environment. | | 2.) | Prevents the formation of ingredients accounting for the bad smell through the reaction of Nano ZnO with thiol molecules to form Zinc Sulfite(ZnS) | | 3.) | Protects the protein from fermenting to prevent the smell from occurring. |
