Traditional usage requires it to be refined with water, and just for temporary use. For external application, it is not suitable for a large scale use or for a long time. It is contraindicated for the pregnant women. Avoid being calcined by fire.

Standard Dosage: No dosage is permissible due to mercury toxicity. 0.1-0.5g in powder or pills is traditional.

Traditional contraindications include overdose and taking for a long period of time, or calcinification.
