In the Orient, deer antler is revered as a potent sexual and longevity tonic strengthening all parts of one's life. It treats hormonal deficiencies, while strengthening the nervous system and heart. The antler of the deer is painlessly removed when it has grown just three spikes and is still covered by velvet. The deer will grow new antlers. The tip of the antler is the most potent part as it contains the most active substances. Modern research indicates that deer antler stimulates the production of blood.
