Velvet antler

Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family, including the species of deer, such as red deer, elk, moose, and caribou. A velvet antler is covered in a hairy, soft "skin" known as velvet, with the developing antler having rounded tines during its annual growth and remaining uncalcified.

Velvet antler preparations are sold in China as part of traditional Chinese medicine, and in some countries as a dietary supplement. Marketing claims of health effects are not supported by scientific evidence, and the US Food and Drug Administration has warned companies selling the products about false advertising.
