Wang Shi, a medicinal material, is different from ordinary jade and has a good nourishing effect on the body. This natural mineral is rich in minerals and trace elements. If worn all the time, these minerals and trace elements will be gradually absorbed by the body, and these minerals and trace elements are just beneficial to the body and are needed by the body. Therefore, wearing Wang Shi necklace can nourish the body.

It has been found that dark green jade has been used to treat diseases in China for over 1700 years. Dark green jadeite is called "Yao Wang Shi" among the people for the following reasons: 1. First of all, it mainly contains a large number of minerals related to health care functions. Geological data show that dark green jadeite is rich in magnetite, actinolite, calcite, biotite and other minerals besides serpentine. Most of these magical mineral medicines have aphrodisiac effect, which is highly recommended by Sun Simiao, a famous TCM health care master in ancient China. The famous ancient medical books Shennong's Classic of Materia Medica and Compendium of Materia Medica have detailed records. 2. Secondly, the test data show that dark green jade has a history of hundreds of millions of years as a pure natural rock primary near the jade mine. Its mineral medicine not only has many health functions such as magnetization, detoxification, aphrodisiac and so on. It also contains 26 minerals and trace elements beneficial to human body, such as calcium, magnesium, iron, zinc and selenium, as well as active substances. 3. Third, although the original color of dark green jade is only white and green, it has evolved into today's "black Bao Gong" after a long geological process. But its precious secondary color black is also beneficial to human health. Because there is a theory that "five colors enter the five internal organs" in TCM health preservation. Accordingly, the black color of dark green jade enters the kidney, which is beneficial to the health of human renal function.
