Maifanshi is a natural silicate mineral, scientific name: quartz monzonite. Maifanshi is a kind of compound mineral or medical rock which is nontoxic, harmless and has certain biological activity The main chemical composition of Maifanshi is inorganic aluminosilicate. It also contains all the constant elements required by animals, about 58 kinds.

　　The resources of Maifanshi are very rich in China, which are distributed in almost all provinces, cities and autonomous regions. The well-known ones that have been developed and applied include Mengyin in Shandong, Naiman Banner in Inner Mongolia, Jixian in Tianjin, Fuxin in Liaoning, Siming Mountain in Zhejiang, Gannan in Jiangxi, Taidong in Taiwan, etc. In addition, there are a lot of mineral deposits in Shandong, Guangdong, Guangxi, Sichuan, Xinjiang, Fujian, Jiangsu, Hubei, Shaanxi, Gansu, Henan, Hebei, Shanxi, Jilin, Heilongjiang and other places. Due to different producing areas, their compositions are slightly different, and their colors are not exactly the same. Among them, Shandong and Inner Mongolia are the best, and the local stone quality is good, so it can be carved and processed After soaked in water, Yimeng Maifanshi can contain nearly 20 elements and minerals necessary for human body, such as potassium, sodium, calcium, magnesium, silicon, ferocity, titanium and phosphorus, which can meet the standard of mineral water. Long term drinking can enhance the immune function of the body and improve the anti infection ability of the body. At the same time, Yimeng Maifanshi has a strong adsorption rate for cadmium, lead and other elements harmful to human body and bacterial colony, and the adsorption rate for Escherichia coli is more than 95.

　　Experts at home and abroad identified that Maifanshi is rich in various trace elements necessary for human body, which can be used for water purification and sewage treatment, and has strong adsorption on bacteria. Drinking Maifanshi water can regulate the metabolism of the body, and has the functions of stomach, diuresis, liver protection and anti-aging, which is of great benefit to human beings The effect of drinking water with Maifanshi water cup: 1. Anticancer effect; 2. Improvement of immune function; 3. Anti-aging effect; 4. Anti fatigue effect; 5. Improvement of hypoxia tolerance; 6. Prevention and treatment of alcohol damage; 7. Promotion of bone salt deposition and shortening of fracture healing time; 8. Anti fluoride effect; 9. Adsorption of bacteria.
