Deer velvet, also referred to as antler velvet, refers to antlers that have been removed during the growth stage, when they are covered with soft velvet-like hair. After removal, the antlers are dried and ground. In Western countries, the ground powder is sold as a dietary supplement that purportedly improves sexual function and overall energy, decreases stress, and strengthens the body. In traditional Chinese medicine (TCM), deer velvet has been used as a yang tonic for the endocrine and immune systems, energy metabolism, growth, and sexual function.
There is currently insufficient available clinical evidence to support the use of deer velvet for any medical use. High-quality clinical studies are needed before safety can be assessed and firm conclusions can be made.
