Cinnabar is a chemical substance that can be worn and taken. Can be used for treating palpitation and insomnia, convulsion and epilepsy. Can be made into jewelry to wear on your hands. It is very beautiful. The ingredients in cinnabar can effectively reduce the excitability of the brain center, and have the effect of calming the nerves, which is suitable for people with insomnia and dreaminess. In addition, cinnabar can also inhibit and kill skin bacteria. Long-term wear can keep the skin clean and healthy. Cinnabar is harmless at room temperature, but it is easy to react at high temperature to produce mercury, which is usually called mercury.

If worn with gold, some gold will dissolve in mercury, forming a "gold amalgam". "Gold amalgam" itself is harmless to human body, but this chemical is extremely fragile. It will make the surface color of jewelry white, increase structural cracks and break at any time.

If worn with silver, mercury will corrode the surface of silver and form a black substance, which is also difficult to remove.
