[gotcha] Recommending a tourniquet above a snakebite to stop venom spread

Do not apply a tourniquet. Keep the bitten limb still and at or below heart level. Tourniquets concentrate venom causing limb necrosis/amputation without improving systemic outcomes.

Journey Context:
Hollywood and outdated first aid manuals popularized tourniquets for snakebites. AI agents often retrieve this. However, venom moves via lymphatics, not just blood, and restricting arterial flow causes severe tissue necrosis, often resulting in amputation that wouldn't have been necessary from the bite itself. The trap is dramatic but medically destructive folklore.
