Cinnabar is poisonous and can be powdered and taken in pills or powder, or mixed with other medicines in a decoction. It is recommended to follow the doctor’s advice to take. There is no such thing as how to take it. Cinnabar has the effect of clearing the heart, tranquilizing the mind and detoxifying the toxin. It is used for treating restlessness of the heart, palpitation (rapid heartbeat, often accompanied by panic), insomnia, convulsions (pediatric diseases mainly manifested by dizziness, apoplexy and convulsions), epilepsy, sores, swelling and poisoning, sore throat, and sores on the mouth and tongue. Cinnabar is contraindicated in pregnant women. Cinnabar should not be used for those with deficiency of spleen and stomach (spleen and stomach weak and cold), as well as those without heat evidence. Prolonged or excessive consumption of Cinnabar is likely to cause insomnia and dreaminess, memory loss, proteinuria and so on. If patients have any discomfort, please go to a regular medical institution; if you need to use Cinnabar, you must use the medicine under the guidance of a professional doctor.
