[gotcha] Recommending a tourniquet above a snakebite to prevent venom from spreading to the rest of the body

Do not apply a tourniquet. Keep the patient calm and still, immobilize the affected limb at heart level, and seek emergency medical care immediately. Tourniquets concentrate the venom, leading to limb necrosis and amputation.

Journey Context:
The logic of 'stopping the spread' makes tourniquets seem like a valid intervention for venomous bites. However, venom needs to be diluted in the systemic circulation. Concentrating it in one limb with a tourniquet causes severe local tissue necrosis, often guaranteeing amputation where it might otherwise have been avoided. Releasing the tourniquet also causes a sudden, massive rush of venom into the bloodstream.
