Jade is a natural mineral and contains many trace elements. China has also enjoyed the reputation of "the land of jade" since ancient times, especially Hetian jade in Xinjiang. Jade has been regarded as a treasure and a symbol of status since ancient times. Ancient medical books said that "jade is the beauty of stone, sweet and flat in taste, and non-toxic". The ancients believed that jade has many benefits to human body, which can nourish human body and relieve summer heat, so jade is also regarded as the top grade of health care.
There are all kinds of jade on the market now, and different jade claims to have different health care functions, such as agate stone has the effect of clearing away heat, white jade has the effect of calming the nerves, sapphire can ward off evil spirits and so on. But have we ever questioned that these jades really have those magical effects?
Jade does contain many trace elements and minerals beneficial to human body, such as zinc, iron, selenium, magnesium, nickel and cobalt. However, the content of these trace elements and minerals in jade is too low to be absorbed by the human body, so wearing jade can not play a health care role.
But why does the spirit of people who wear jade really get better, and the original pains seem to dissipate a lot, as if they really have those health care functions? Can only say that more is just psychological comfort and suggestion.
There is a folk saying about why jade wears more luster: "Jade raises people and people raise jade". But in fact, this is not the case. The reason why jadeite becomes smooth and bright is only because it rubs against clothes and the skin next to it for a long time, and also because the oil secreted by the human body every day will become more and more moist in the long run.
