Velvet antler is said to be effective as an anti-inflammatory, anti-cancer, immune stimulant, and pro-growth agent. Velvet antler refers to the whole cartilaginous antler in a pre-calcified stage. The deer antler is typically cut off near the base when it is about two-thirds of its potential full size, but before any significant calcification occurs.
All members of the deer family, will produce new antlers yearly. The bulls are not harmed by antler removal. After the antlers are cut off a small antler pair to replace them may regrow, but the antler base is left. That base will be shed early the following year when the whole antler would have been shed and a new pair antlers starts to grow.
