Medical stone is a natural monzonite porphyry with biological and medical effects. It is light yellow or gray, so it is named because it looks like a ball of wheat rice. It is a collection of various minerals, including 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. Plagioclase and potash feldspar are dominant, followed by Shi Ying, hornblende, biotite and by-product phosphide. Under normal conditions, the contents of four trace elements (metasilicic acid, Sr, Zn, F) in the medical stone dissolution solution reached or approached the national standard of beverage mineral water.
