Ling Yang Jiao is the horn of the saiga antelope. In Chinese medicine it is used as a single herb for very high fever, fits, and bad headaches. It is also called antelope horn.
The saiga antelope is endangered. Trade in its horn is banned or tightly limited in most countries. Buying or selling it may break the law where you live.
Human trial evidence is thin. Long use in a tradition is not proof that a remedy works, and that holds here. Many products sold under this name now use other horn or other herbs instead.
No one has shown clearly how it acts in the body. Horn is mostly keratin, the same tough protein found in your hair and nails. Keratin is hard to break down, so little may reach your blood.
In Chinese medicine it is said to cool the liver and calm wind. That is old language for hot, shaking illness. It is not a body process you can measure.
Some lab and animal work hints at lower fever and a calming effect. That work has not been matched by good human trials, so treat it as an idea, not a finding.
The classic form is thin shavings of horn, boiled for a long time in a tea with other herbs. A very fine powder is also used, stirred into the finished tea or taken on its own.
It appears in ready-made Chinese formulas, granules and pills. Ling Jiao Gou Teng Tang is the best known of these.
Because of the trade ban, most modern products use goat horn (Shan Yang Jiao) or plant herbs in its place. The label may still carry the old name, so check what is really inside.
Ling Yang Jiao appears in the Shen Nong Ben Cao Jing, a Chinese herb text from about 2,000 years ago. It was kept for the most severe cases of fever with fits.
It stayed a named staple of Chinese medicine through the centuries and is listed in the Chinese Pharmacopoeia. Its standing rests on one tradition, not on many.
Some reactions to Ling Yang 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.
Call emergency services at once for a fit, a stiff neck, a rash that does not fade under pressure, trouble breathing, or a child who is floppy or hard to wake.
See a doctor the same day for a fever above 39C, a fever that lasts more than three days, sudden severe headache, or eye pain with blurred sight.
Stop the herb and speak to a doctor if you get a rash, swelling, stomach pain, or feel worse after taking it.
