A favored medicine in the ancient Traditional Chinese Medicine (TCM) system, deer antler velvet is a type of cartilaginous tissue found in early-growth antlers. It isnât the velvet that covers young antlers, but the tissue found inside the antlers prior to calcification â when antlers become very hard.
Female caribou are the only female cervids that have antlers. Antlers form on the heads of deer just before breeding season. These antlers start as two velvet covered spikes with spongy bone inside. As the bone grows, calcifies, and hardens the velvet starts to drop off and shed. A male deer in velvet is called a velvet buck. The deer rubs this velvet on trees and branches, leaving behind the exposed dead bone core which can be quite sharp.
