Xi Jiao Di Huang Tang (Rhinoceros Horn and Rehmannia Decoction)

Actions

Indications

Western Uses:

• What is Xi Jiao Di Huang Tang used for in modern practice?

  In modern practice Xi Jiao Di Huang Tang (built on the Shui Niu Jiao substitute) is referenced within the Wen Bing framework for acute febrile illness with hemorrhagic or purpuric signs — historically applied to presentations such as bleeding disorders, purpura, and severe infectious/eruptive fevers with a hemorrhagic rash, where Western medicine recognizes categories such as disseminated intravascular coagulation, thrombocytopenic purpura, or hemorrhagic fever. Contemporary Chinese research on modified versions of the formula has also explored sepsis, systemic lupus erythematosus skin lesions, and Kawasaki disease’s coronary artery inflammation (see research).

  These biomedical correlates are offered as a reference to the formula’s traditional use, not as a claim that it treats any disease. Bleeding, purpura, high fever, or altered consciousness are all indications for urgent evaluation by a qualified practitioner and, where warranted, emergency medical care — this formula is not a substitute for either.

Notes:

• How is Xi Jiao Di Huang Tang different from Qing Ying Tang, and how is it modified?

  Xi Jiao Di Huang Tang and Qing Ying Tang both clear heat from deep, late-stage warm-febrile disease, but they sit at adjacent levels in Ye Tianshi's wei-qi-ying-xue model. Qing Ying Tang treats heat at the nutritive (ying) level, before frank bleeding appears; Xi Jiao Di Huang Tang treats heat one stage deeper, at the blood (xue) level, once bleeding or blood stasis has actually developed — and correspondingly drops Qing Ying Tang's heat-venting herbs (Jin Yin Hua, Lian Qiao), since at the blood level there is no longer a qi-level pathway left to vent heat back out through.

  • For reckless bleeding (hematemesis, epistaxis, blood in stool/urine): commonly add hemostatic herbs matched to the bleeding site, such as Bai Mao Gen or Ce Bai Ye, and San Qi to stop bleeding while also moving blood.
  • For heat with blood stasis (mania/delirium, forgetfulness, dark stool, fixed abdominal masses): commonly add Da Huang and Huang Qin to drain heat and break up stasis — reflecting the formula's classical dual use for both “reckless bleeding” and “accumulated blood” presentations.
  • For heat-toxin sores or deep-set swellings: add Jin Yin Hua, Lian Qiao, and Xuan Shen to strengthen toxin-resolving action.

Clinical Studies & Research:

• Is there modern research on Xi Jiao Di Huang Tang?

  Yes, though it is largely mechanistic/preclinical research on modified or reformulated versions of the decoction (built around the Shui Niu Jiao substitute) rather than clinical trials of the classical formula itself. Studies frame the formula's traditional "clear heat, cool and invigorate the blood" action in terms of modern inflammation, coagulation, and immune-signaling pathways.

  • Blood-heat and blood-stasis syndrome (serum pharmacochemistry + network pharmacology): identified 60 serum-absorbed constituents of Xijiao Dihuang Tang and reported broad effects on inflammation, coagulation, oxidative stress, and apoptosis via the p38 MAPK pathway in animal and cell models (PMID 35178159).
  • Sepsis (animal model): a modified Xi-Jiao-Di-Huang decoction reduced organ damage and cytokine release in septic mice, associated with shifting macrophages from a pro-inflammatory (M1) toward an anti-inflammatory (M2) state by inhibiting the PIM2/NF-κB signaling pathway (PMID 40248592).
  • Kawasaki disease coronary artery injury (animal + cell model): reduced coronary artery inflammation and endothelial injury in a Candida-albicans-induced mouse model of coronary arteritis and a TNF-α-stimulated cell model, associated with the PI3K/Akt–NFκB signaling pathway (PMID 34665368).
