Hua Rui Shi is a mineral used in Chinese medicine. Its other name is Ophicalcite. It is a rock made of chalky white stone mixed with green serpentine stone.
It is used as a single drug, not as a blend. Old texts use it to stop bleeding. Healers grind it to powder, dust it on wounds, or give small amounts by mouth.
The proof is thin. We found no human trials of this mineral. It has a long record of use in one tradition, but use over time is not the same as proof that it works.
No one has shown how this rock acts in the body. The ideas below come from tradition and from guesswork, not from trials.
The old idea is simple. The powder is dry and soaks up fluid. On a cut, a dry powder may help a clot form and hold.
Chinese medicine says it stops bleeding and moves stuck blood. That is a theory from within that system. It has not been tested in people, so treat it as untested.
It comes as a raw stone, as a fine ground powder, and as a calcined powder (the stone is baked in a fire first, then crushed). Some shops sell it inside ready-made Chinese formulas.
For drinks, the crushed rock is boiled in a cloth bag so grit stays out of the cup. For skin use, the fine powder is dusted straight onto a small cut.
Quality varies a lot. Ask the seller for a test report for lead, arsenic and other metals before you buy.
Hua Rui Shi is listed in Chinese drug books from the Song era, about a thousand years ago. It has stayed in use since then, mostly as a bleeding remedy.
It is best known inside a classic powder that pairs it with San Qi for coughing or vomiting blood. Army and folk healers also kept it as a wound dust.
So its standing in tradition is strong. Its standing in modern testing is close to empty.
Some reactions to Hua Rui Shi need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
See a doctor the same day if you cough up or vomit blood, pass black or bloody stools, or bleed from the back passage.
Go to an emergency department if bleeding will not stop after ten minutes of firm pressure, if blood soaks through a dressing, or if the person feels faint, cold, sweaty or confused.
Also call your doctor if you feel very thirsty, sick, weak or muddled after taking this by mouth, as these can be signs of too much calcium in the blood. Tell any doctor or pharmacist that you have used it, because it changes how some medicines are absorbed.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Hua Rui Shi is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
