Lu Jiao (Deer Horn)

Chinese Herb Actions

Chinese Herb Dosage

• What is the typical dosage of Lu Jiao, and how is it prepared?

  Commonly cited as roughly 5–15 g in decoction (published ranges vary, from about 3 g up to 15 g across sources) or 1–3 g as a fine powder taken directly, mixed into a decoction, or applied topically as a paste for sores and swellings. Because it is a hard, ossified material, it is traditionally sawn or shaved into thin slices or filings and given a longer simmer than the other herbs in a formula to extract its constituents.

  Note: commercial and secondary references give somewhat different decoction ranges (e.g. ~3–10 g vs ~6–15 g); this likely reflects different source editions/regions rather than a real clinical disagreement, so a broad 5–15 g range is given here.

Chinese Herb Contraindications & Cautions

• Are there cautions for Lu Jiao?

  Lu Jiao is warm, yang-tonifying, and blood-invigorating, so it is contraindicated in patterns of yin deficiency with heat or effulgent (excess) fire — where it would be expected to aggravate night sweats, hot flashes, or agitation — and in active febrile/heat conditions generally. Because it moves blood, it is used cautiously in pregnancy. As with other strongly acting animal substances, it is best used under a qualified practitioner, particularly toward the higher end of the dosage range or for extended courses.

  • Dietary/ethical (reference note) — Lu Jiao is an animal-derived product (deer antler) and is not suitable for vegetarians or vegans; the animal source should be disclosed.
  • Sourcing/species (reference note) — it is collected from farmed Cervus elaphus (red deer) or Cervus nippon (sika deer), either as antler naturally shed each spring or sawn from the animal in autumn/winter once fully ossified (a painless removal of dead bone, unlike the surgical harvesting of growing velvet). This site’s own record flags this entry for endangered-species/sourcing sensitivity; species and CITES status are worth confirming with the supplier at purchase.

Chinese Herb Toxicity & Overdose

• Low. Lu Jiao is classified as non-toxic in the materia medica; it is composed mainly of calcium phosphate, collagen, amino acids, and trace minerals, and no significant intrinsic toxicity is reported at standard reference doses. The main real-world concerns are not intrinsic toxicity but (a) inappropriate use in heat/yin-deficiency-fire patterns given its warming nature, and (b) product authenticity — Cornu Cervi can be visually and analytically confused with the related Cornu Cervi Pantotrichum (velvet) and Cornu Cervi Degelatinatum (residue) products, which is why spectroscopic identification methods have been developed (see Research).

Herb-Drug Interactions

• No well-established clinical herb–drug interactions are documented for Lu Jiao specifically. Given its traditional blood-invigorating action, practitioner awareness is reasonable for patients on anticoagulant or antiplatelet therapy — this is precautionary, not a demonstrated clinical interaction.

Western / Biomedical Research

Chinese Herb Clinical Studies & Research

Provided as research context — a summary of published biomedical study, not a therapeutic or medical claim.

• Is there modern research on Lu Jiao (Cornu Cervi)?

  Yes, but it is a small and mostly preclinical literature, and it is easy to confuse with research on the velvet (Lu Rong) instead. A 2013 review in the Journal of Ethnopharmacology focused specifically on deer antler base (Cornu Cervi, i.e. the mature, ossified antler covered by this entry, as distinct from the growing velvet) traced its recorded use back roughly 2,000 years to classical materia medica, and summarized decades of laboratory and animal studies reporting immunomodulatory, anti-cancer, anti-fatigue, anti-osteoporotic, anti-inflammatory, analgesic, antibacterial, antiviral, antioxidant, hypoglycemic, and hematopoietic-modulatory activity, attributed mainly to its amino acids, polypeptides, and proteins.

  • Traditional-use and pharmacology review (preclinical) — the 2013 review above; the authors note that, unlike velvet antler, antler base had been comparatively neglected by researchers, and that most supporting evidence remains at the cell/animal-study stage rather than controlled human trials.
  • Authentication (analytical chemistry) — a spectroscopic (FT-IR / 2D-IR) study successfully distinguished Cornu Cervi Pantotrichum (velvet), Cornu Cervi (this herb), and Cornu Cervi Degelatinatum (residue) from one another by their protein (amide I/II) and calcium-phosphate spectral signatures — useful given how easily the three look-alike products are confused or substituted in trade.

  No controlled human clinical trials specific to Cornu Cervi (the mature antler) were identified; human research in this family more often targets the velvet (Cornu Cervi Pantotrichum) or the gelatin (Colla Cornus Cervi), which are covered under Lu Rong and Lu Jiao Jiao respectively.

Chinese Herb Notes

• How does Lu Jiao compare with Lu Rong, Lu Jiao Jiao, and Lu Jiao Shuang?

  Lu Jiao sits second in the deer-antler processing family, as the hardened, fully ossified antler that the soft young velvet (Lu Rong) becomes once it stops growing. The family runs, strongest tonic to weakest: Lu Rong (soft young velvet) → Lu Jiao (hardened mature antler, this herb) → Lu Jiao Jiao (gelatin rendered from it) → Lu Jiao Shuang (the degelatinated residue left after the glue is extracted). Blood-moving/swelling-reducing strength runs the other way — Lu Jiao is the strongest of the four at this action.

  • Lu Rong (velvet of the young, growing antler) — the strongest and most warming; the principal Kidney-yang, essence, and blood tonic, reserved for deep constitutional deficiency; weaker than Lu Jiao at moving blood and reducing swelling.
  • Lu Jiao (this herb, the hardened mature antler) — considerably weaker tonic than Lu Rong; its main distinguishing strength is invigorating blood and dispersing cold-toxin swellings/sores.
  • Lu Jiao Jiao (gelatin/glue rendered from Lu Jiao) — more focused than Lu Jiao on nourishing essence and blood and on stopping bleeding (particularly deficient-cold uterine bleeding); gentler and more moistening, but loses Lu Jiao’s blood-moving action.
  • Lu Jiao Shuang (degelatinated antler residue) — the weakest tonic of the four; mildly astringent, used to help stop bleeding/discharge and for external sores.

  No formulas in this site’s own record currently link to this herb (Lu Jiao Jiao appears in You Gui Wan and Yang He Tang instead); this note will be updated if that changes.
