What is Shui Niu Jiao?
Shui Niu Jiao is horn from the water buffalo. The horn is shaved into thin chips or ground into powder. Chinese medicine uses it as a cooling drug for high fever.
It is a single drug, but it is rarely used alone. It is one part of a mixed formula. Healers give it for high fever with a rash, for nosebleeds, and for other bleeding.
It took the place of rhino horn, which is now banned worldwide. Long use in one tradition is not proof that a drug works. Good human trials are missing, so the evidence grade here is insufficient.
How does Shui Niu Jiao work?
The honest answer is that no one has shown how it works in people.
The horn is mostly keratin. That is the same hard protein found in your nails. Lab work breaks the horn into small protein bits.
Some of these bits lower fever in mice. Some seem to change how fast blood clots in a test tube. None of that has been shown to hold true in people.
In Chinese medicine the horn is said to "cool the blood" and "clear heat toxin". That is a way of sorting signs and symptoms. It is not a proven body process.
What forms does Shui Niu Jiao come in?
You will most often meet it inside a mixed formula, not on its own.
Common forms are thin horn shavings for boiling, a fine powder, and dried extract granules. It is also pressed into ready-made pills.
Some ready-made pills that hold this horn also hold cinnabar (a mercury mineral) or realgar (an arsenic mineral). Both are heavy metals and both can poison you. Read the full label before you buy.
Where it comes from:
Water buffalo horn appears in Chinese drug texts from the Ming era, including Li Shizhen's Bencao Gangmu of 1578.
For centuries it sat in the shadow of rhino horn, which was the famous fever drug. World trade in rhino horn was banned in 1977, and China banned its use in 1993.
Since then, water buffalo horn has been the standard stand-in. It is now written into modern Chinese formula books in rhino horn's place.
If this is an emergency
Some reactions to Shui Niu Jiao need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Who should avoid Shui Niu Jiao?
- Do not use if you are pregnant.
- Do not use if you are breastfeeding.
- Never give it to a baby or child unless a doctor has told you to.
- Never buy or use a product whose label lists cinnabar (a mercury mineral) or realgar (an arsenic mineral).
- Never use rhino horn in its place. Trade in it is illegal and the animals are endangered.
- Do not use if you take warfarin, aspirin, clopidogrel or any other blood thinner, unless your doctor agrees.
- Do not use if you have a bleeding disorder such as haemophilia (a condition where blood does not clot well).
- Do not use if you have low blood platelets (the cells that help blood clot).
- Do not use if you have a surgery booked in the next two weeks.
- Do not use if you feel cold often, have weak digestion, or have loose stools. Chinese medicine calls this a cold pattern and treats it as a reason to avoid this cooling drug.
- Do not use if you have kidney disease or liver disease, unless your doctor checks the product first.
- Do not use it instead of seeing a doctor for a high fever, a spreading rash, or bleeding that will not stop.
When should you see a doctor?
Get medical help right away if a fever goes above 39.5C, or if a fever lasts more than two days.
Go to an emergency room if you see a rash that spreads fast, a stiff neck, confusion, a fit, or trouble breathing. Do the same for bleeding that will not stop.
Call your doctor if you get new bruises, bleeding gums, dark urine, yellow skin or eyes, or a shaky, numb feeling in your hands or feet. Those last signs can mean heavy metal poisoning from a mixed pill.
