Efficacy and function of cinnabar: do not wear it.
Efficacy of cinnabar: Cinnabar has been one of the traditional Chinese medicines since ancient times. Its main function is to soothe the nerves and can help improve people's sleep effect. At the same time, cinnabar also has a very good bactericidal effect. This is the main function of cinnabar, so cinnabar has become one of Chinese herbal medicines.
It is forbidden to wear cinnabar: However, cinnabar contains a lot of mercury sulfide, so it can't be worn for a long time, which will be harmful to human health. Nowadays, many people like to wear cinnabar for a long time, which is actually not desirable. It is ok to wear it for a short time, but not for a long time, otherwise it will not only have no health care effect but also endanger health.
In addition, cinnabar can't directly touch the mouth. If you want to take cinnabar orally, you must have a professional doctor's advice and use it according to the doctor's requirements. Otherwise it may be poisoned. The main material of ancient alchemy was cinnabar, which emperors liked to eat, but many emperors died directly because they ate too much Dan medicine.
Finally, cinnabar has another function, which is to ward off evil spirits. I believe this is what many people learned when they first contacted cinnabar. The spells at that time were all painted with cinnabar. Ancient people also believed that cinnabar could ward off evil spirits and keep peace, so they usually wore cinnabar to protect themselves. But in fact, this is a kind of folklore, so you don't have to care too much.
