It has been found that dark green jade has been used to treat diseases in China for over 1700 years. Dark green jade is called "Medicine 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.

Yao Wang Shi appeared:

Hidden jade is big and small, big like a stone, small like a fist like a pearl. There is a layer of dark green or dark black "Bao Gong Black" spots on the surface, dark green spots similar to frogs and snakeskin, and some yellow spots with cauliflower, so some people call them frog green and snakeskin green. Other color patterns are like Gu Mei Pride, and some have veins between Bai Shiying, forming patterns. This kind of jade is difficult to form, with high hardness and fine stone.

Only in Kunlun Mountain in China and Brazil in America, there are few reserves. It is reported that at the end of the 20th century, the primary mineral reserves of dark green jade were only 36,000 tons. Wuhan Kistler Museum still has a certain amount of jade. Therefore, the primary minerals of dark green jadeite are non-renewable, and the resources are increasingly scarce.
