[gotcha] Advising the application of a tourniquet to isolate venom after a snakebite

Advise against tourniquets. Instruct the user to keep the bitten limb still and lower than the heart, and seek emergency medical care immediately. Use a pressure immobilization bandage only if trained and if neurotoxic snakes are native to the region.

Journey Context:
First-aid tropes from movies and outdated guides suggest tourniquets to stop venom from reaching the heart. In reality, venom travels largely via the lymphatic system, and a tight tourniquet concentrates the venom in one limb, often leading to amputation. When released, it also causes a massive sudden bolus of venom to enter the bloodstream. The WHO explicitly advises against arterial tourniquets for snakebites.
