Lu Jiao Shuang鹿角霜
Cornu Cervi Degelatinatum · Degelatinated Deer Antler
Overview
What is left of mature deer antler once the gelatin has been boiled out to make Lu Jiao Jiao 鹿角胶 — a chalky, porous, mineral-rich residue. Salty, astringent and warm, it is the gentlest member of the deer-antler group: it warms and steadies Kidney yang without the cloying richness of Lu Rong or the glue, which makes it the practical choice for a patient whose digestion cannot cope with a heavy tonic. Its astringency is the second half of its usefulness — it holds in thin vaginal discharge, seminal loss and deficient uterine bleeding, and powdered it dries weeping sores.

Cautions
Warming and astringent: unsuitable where there is yin deficiency with heat signs, or an active heat or infectious pattern. Because the gelatin has already been extracted, it holds very little of what actually fills blood and essence — where that is the aim, Lu Jiao Jiao 鹿角胶 or Lu Rong 鹿茸 is the correct herb, and substituting Lu Jiao Shuang there quietly underdoses the patient. Decoct it first; it is a hard mineral material. It is animal-derived and therefore unacceptable to patients avoiding animal products, who should say so before dispensing. Our dispensary data flags no toxicity and no allergy risk.
Contraindicated in pregnancy: No specific restriction — practitioner judgment applies; warming yang tonics are prescribed case by case in pregnancy
