Some societies, such as the Moche, had ritual hematophagy, as well as the Scythians, a nomadic people of Russia, who drank the blood of the first enemy they killed in battle. Some religious rituals and symbols seemingly mirror hematophagy, such as in the transubstantiation of wine as the blood of Jesus Christ during Christian eucharist. Psychiatric cases of patients performing hematophagy also exist.
