Live bats are sold in Bolivia for purported medicinal uses. Specifically, consuming the bats' blood is believed to treat epilepsy.[1] A 2010 study documented that per month, 3,000 bats were sold in markets in four Bolivian cities. Species sold in these markets include Seba's short-tailed bats, mouse-eared bats, and common vampire bats.[2] Bat excrement (guano) is used in traditional Chinese medicine as a treatment for night blindness.[3] The Romans believed that bat blood was an antidote for snake venom.[4]
