Antivenom is often made using antibodies produced by horses or other animals exposed to venom.

means A medicine made from antibodies that neutralizes the toxins in venom from snakes, spiders, or other venomous creatures.

from From 'anti-' (against, from Greek) plus 'venom,' which traces back through Old French 'venim' to Latin 'venenum,' meaning poison or magic potion. The horse connection isn't etymological but procedural — the word just means 'against poison,' but the making of it has long relied on injecting a large animal, usually a horse, with small amounts of venom and harvesting the antibody-rich plasma that results. Science named the shield but stayed quiet about the stable.
