Lu Jiao鹿角
Cervi Cornu · Deer Antler · Hartshorn
Overview
- ·.*
The fully ossified antler of the sika or red deer — the hard, bony, branched antler, quite distinct from Lu Rong 鹿茸, which is the same organ taken in spring while it is still soft, blood-filled velvet. Antler is either shed naturally at the end of the season (, the preferred source) or cut from a farmed animal.
Salty and warm, entering Kidney and Liver. It warms Kidney yang, strengthens the sinews and bones, and — this is what separates it from Lu Rong — moves blood and reduces swelling. It is much weaker than velvet at tonifying and cannot replace it where real deficiency needs filling, but it does something velvet does not: it disperses. That gives it a place in the treatment of cold, deep-seated abscesses and early breast abscess, where a warming, blood-moving tonic is exactly what the pattern calls for.

5–15 g in decoctionActions
4 core actions
- Warms Kidney yangKidney yang deficiency with impotence, seminal emission, a cold aching lower back and knees, and frequent clear urination. Milder than Lu Rong — a supporting herb rather than a powerful one.
- Strengthens sinews and bonesWeak, sore lower back and knees, and delayed development in children, in the classical record. Its salty warmth reaches the Kidney, which governs the bones.
- Moves blood, reduces swellingThe action Lu Rong does not have. Cold, deep, non-healing abscesses, early breast abscess before it suppurates, and swelling and pain from blood stasis. Externally the powder is applied to the swelling. This is the reason a practitioner would choose the hard antler over the velvet.
- Antler, glue and residueLu Jiao Jiao, the gelatin boiled down from the antler, warms and supplements Liver and Kidney, nourishes essence and blood and also stops bleeding, and is dissolved into a hot decoction at 3–6 g. Lu Jiao Shuang, the spent residue left after the glue is extracted, warms Kidney yang more weakly but is astringent and stops bleeding and discharge, at 9–15 g, decocted first. Three products from one antler, with three different balances of tonifying and dispersing.

Contraindications
Cautions
- Warm — not for heat or yin deficiency. Contraindicated where yin is deficient and fire is flaring: night sweats, hot palms and soles, a red tongue with little coating, easily provoked erections. It is also unsuitable in any hot abscess that is already red and inflamed — its place is the cold, pale, deep-seated kind.
- It moves blood. Use with caution alongside anticoagulant or antiplatelet medication, and stop it before surgery.
- Do not confuse it with Lu Rong. Lu Rong is the soft, unossified velvet, much stronger, much more expensive, dosed at 1–2 g of powder. Lu Jiao is the hard bone. Substituting one for the other in either direction is a real dispensing error — one under-treats a serious deficiency, the other over-warms a patient who did not need it.
- Sourcing and legality. Deer antler must come from farmed animals through a licensed supplier with documentation. Sika deer (Cervus nippon) is a Class I protected species in China and red deer (Cervus elaphus) is Class II, so wild-taken antler is illegal, and some deer subspecies are listed under CITES. Cross-border shipment of animal-derived medicinal material may require CITES paperwork and veterinary certification, and several countries restrict animal products in medicines and supplements outright. Check before ordering from abroad, and refuse material whose origin cannot be documented.
- Not for the patient population it is most often sold to. Antler products are marketed widely as a general tonic. Warming the Kidney yang in someone who is hot, dry or agitated makes them worse, and long unsupervised use of a warming tonic is a common way for a patient to arrive with a worse pattern than they started with.
- A lump, a breast lump especially, needs diagnosis. Any breast swelling requires medical assessment. Treating it as an early abscess without knowing what it is delays a diagnosis that may matter a great deal.
Contraindicated in pregnancy: Use with caution in pregnancy, and avoid it in practice: it is strongly warming and it moves blood, and neither is wanted during pregnancy. It also raises the risk of heat symptoms in a pregnant woman who is already warm. Any use requires the treating practitioner's decision. Safety in breastfeeding has not been established.
