Cinnabar is a very positive mineral and a sedative. Taking large amounts can cause poisoning. In Feng Shui, because its yang is extremely strong and makes evil things fearful, it is often used as an evil spirit in Feng Shui. If it is taken by a sick person, it is necessary to follow the doctor's instructions and take it with caution to avoid poisoning if the dosage is exceeded; if it is used to ward off evil spirits, it does not matter if you are sick or not, you can take it with you. Cinnabar is the most indispensable fetish in Feng Shui. A professional onmyoji can make charms, wear charms, and write epitaphs.
