The northern medical stone has a strong adsorption capacity for several elements harmful to human body, such as cadmium, mercury, arsenic and lead. It also has a good adsorption capacity for pathogenic bacteria such as Escherichia coli, Shigella dysenteriae, Staphylococcus aureus and Candida albicans. It has strong adsorption on chlorpromazine and weak adsorption on barbital. It can purify water.
The latest application of medical stone The latest application of medical stone in life, people mainly make a series of medical stone products such as medical stone water dispenser, medical stone tea set, medical stone bowl and medical stone pot. With the progress of science and technology, people will produce more products about medical stone and enrich people's daily necessities.
Medical stone contains major elements such as potassium, sodium, calcium, magnesium and phosphorus, and eighteen trace elements such as zinc, iron, selenium, copper, strontium, iodine, fluorine and metasilicic acid. Under normal circumstances, the contents of four trace elements (metasilicic acid, strontium, zinc and fluorine) in medical stone solution reach or approach the national standard of beverage mineral water. Songshan medical stone is beneficial and harmless to human body. It has a broad development prospect in the aspects of human mineral nutrition source, water purification, breeding and planting.
Extended data
Medical stone belongs to volcanic rocks, and the main mineral is volcanic rocks. 50-75.5 million years ago, the lava erupted from the volcano was buried underground, and after the high humidity and high heat in the volcanic zone, these lava were transformed into acidic substances, and finally medical stone was formed under the pressure of crustal changes. It can be inferred that medical stone is produced in volcanic zone.
China is rich in medical stone resources, and the famous ones that have been developed and applied are Mengyin, Shandong, Naiman Banner, Inner Mongolia, Jixian, Tianjin, Fuxin, Siming Mountain and Gannan, Jiangxi, among which Inner Mongolia and Shandong are the best. Because of its strong adsorption and purification of water, it is widely used, especially for crops.
The quality of medical stone produced in different places varies greatly, among which Shandong and Inner Mongolia are the best, and the local stone is of good quality and can be carved. In some areas, the formation of medical stone is late, and the stone is loose, so it can only be crushed and pressed again.
