Velvet antler is the whole cartilaginous antler in a pre-calcified growth stage of the Cervidae family including the species of red deer, sika deer, fallow deer and elk. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing.

Velvet antler has been used in traditional Chinese medicine (TCM) that classifies many similar substances from a variety of species under the simplified Chinese name 鹿茸; (pinyin Lu Rong). The two common species used within the TCM system are sika deer and red deer which are thought to be useful for treating yang deficiency syndromes.

In Asia, velvet antler is dried and sold as slices, or as a powder which may be boiled in water, usually with other herbs and ingredients, and consumed as a medicinal soup. In the traditional commercial trade of Korea and China, whole stick antler velvet is divided into three sections based upon their supposed properties. These sections are known as the tips or wax  pieces , the blood piece (‘A’ grade), and the bone piece (‘B’ grade): the wax piece may be marketed as a growth tonic for children, the blood piece supposedly for joint and bone health, and the bone piece supposedly for calcium deficiency and geriatric needs.
