• Chinese name: 鹿角 (Lu Jiao)
• Latin name: Cornu Cervi
• Nature: Warm

Lu Jiao is the hardened, mature antler of the deer, distinguished from its velvet counterpart Lu Rong by a stronger blood-invigorating character alongside its yang-tonifying function. It enters the Kidney and Liver channels to warm the Chong and Ren vessels, strengthen sinews and bones, and promote circulation in areas of cold-type stagnation. Classically employed for both deficiency patterns and yin-type abscesses, it bridges tonification and dispersion in a single herb.
