Known in TCM as Xi Jiao (犀角), this bitter and salty, cold herb enters the Heart, Liver, and Stomach. Traditionally, it clears heat and cools the blood ... Xi Jiao is the classical animal horn for severe blood-heat, crimson eruptions, agitation, and high fever entering the nutritive and blood levels, most often applied for fever, pharyngitis, and mouth sores. Modern research has identified Keratin among its active constituents.

Traditional Use
Primary Actions
- Clears heat and cools the blood ... Xi Jiao is the classical animal horn for severe blood-heat, crimson eruptions, agitation, and high fever entering the nutritive and blood levels.
- Stops reckless bleeding ... traditional indications include epistaxis, hematemesis, blood in the stool or urine, and other bleeding driven by intense heat rather than deficiency.
- Resolves toxicity and calms convulsive heat ... historical use extends to swollen painful throat, dark eruptions, delirium, febrile convulsions, and heat-closing disorders.
Secondary Actions
- This is a prohibited endangered-animal medicine in modern practice ... the clinically accepted substitute is `buffalo-horn`, usually at a much higher dose.
- The historical status of Xi Jiao still matters for understanding old formulas, but that does not justify trade, purchase, or use of actual rhinoceros horn today.
Classic Formulas
- Xi Jiao Di Huang Tang ... hallmark blood-heat formula in which Xi Jiao cools deep heat and stops reckless bleeding.
- Qing Ying Tang ... nutritive-level heat formula where Xi Jiao historically cleared severe internal heat and agitation.
- An Gong Niu Huang Wan and related emergency formulas ... old versions include Xi Jiao for heat-closing patterns, but modern practice substitutes Shui Niu Jiao.
Classical References
- Traditional materia medica describes Xi Jiao as bitter, salty, and cold, entering the Heart, Liver, and Stomach to cool blood, resolve toxicity, and stop heat-driven bleeding or convulsions.
- Modern classical reading requires a substitution note ... when old formulas say Xi Jiao, present-day practice almost always means the buffalo-horn replacement.
Modern Research
Active Compounds
- Keratin proteins ... the principal structural material of rhinoceros horn
- Mineral and trace-element fractions ... chemically variable components studied in authenticity and comparative analyses
- Horn peptide and hydrolysate fractions ... the main laboratory form used in historical pharmacology experiments
Studied Effects
- A 1991 ethnopharmacology study found antipyretic activity in prescriptions containing rhinoceros horn and reported that water buffalo horn could serve as a practical substitute, which is directly relevant to modern formula interpretation (PMID 1943172).
- Mass-spectrometry work on rhinoceros keratin highlights that the horn is fundamentally a keratinous wildlife product rather than a unique mineral or botanical medicine, reinforcing the importance of wildlife-forensic identification (PMID 30230063).
- A review of animal products in traditional Chinese medicine emphasized the environmental, ethical, and health hazards surrounding products such as rhino horn, supporting the conservation-first framing of this record (PMID 12801499).

Safety & Interactions
Contraindications
- Any attempt to purchase, trade, or use real rhinoceros horn
- Use in place of legal and accepted modern substitutes
- Any assumption that endangered-animal sourcing is justified by classical formula history
Cautions
- Real rhinoceros horn is prohibited and conservation-sensitive, and this page is historical-educational rather than a usage endorsement.
- Modern practice uses buffalo horn as the substitute for classical Xi Jiao logic.
- Internet trade in so-called rhino-horn products carries obvious legality, fraud, and wildlife-trafficking risk.
