And gold is generally harmless to the human body, there may be two reasons. First, gold may be mixed with other substances, which means that the purity of gold is not enough. For example, there may be only one layer of gold plating on the surface. Second, individuals are allergic to gold, but not because of gold, but because of personal physique. After all, there are many allergens, some people are allergic to pollen, some people are allergic to cats and dogs, and some people are even allergic to certain vegetables. This individual reason cannot define that gold is harmful to health.
In addition, the local infection caused by Dai Jin is actually caused by injuries that have not been treated in time. Because wearing earrings will rub the roots of the ears, so will wearing bracelets and necklaces. When rubbing against the skin, the skin will be scratched. Because the wound is not treated in time, it will fester due to bacterial infection in hot summer. This phenomenon rarely happens, but it may exist. But pus and infection are caused by friction, or the wound is not treated in time, not because gold is harmful to the skin. On the contrary, gold has antibacterial effect and can play a certain anti-inflammatory and bactericidal role.
