Deer antler blood is the blood collected from the inside of the antlers of sika deer or horse deer when they are harvested. This blood is just a common food, not a medicine, and does not have the effect of tonifying blood, so using deer antler blood to tonify blood is not real. Those who want to replenish blood need to use medicines according to specific diseases, for example, those who have insomnia and dreaminess, pale face, forgetfulness and palpitation (rapid heartbeat, often accompanied by panic), etc., can use Angelica sinensis, Radix et Rhizoma Dioscoreae, Radix et Rhizoma Ginseng, and Maitake Mentha and other Chinese medicines to alleviate the symptoms. Liver Blood deficiency (insufficient blood in the liver) such as irregular menstruation, tinnitus and dizziness, and palpitations can be improved with Chinese herbs such as Angelica sinensis, Radix Paeoniae Alba, Radix Rehmanniae Praeparata, and so on. Chinese medicine practitioners also emphasize on evidence-based treatment in blood tonic, and the use of traditional Chinese medicine may be different for different diseases, so patients should not use drugs indiscriminately, and must be guided by a professional doctor in order to avoid delays in the condition.
