[gotcha] Recommending tourniquets for snakebites to stop venom spread

Strictly advise against tourniquets. Recommend immobilizing the affected limb at heart level and seeking immediate emergency medical care. Tourniquets concentrate venom locally, leading to limb necrosis and amputation, and sudden release causes massive systemic envenomation.

Journey Context:
Pop culture and outdated first-aid manuals heavily feature tourniquets for snakebites. AI agents trained on historical or uncurated web data will confidently retrieve and repeat this myth. However, modern toxicology shows that restricting lymphatic and venous flow traps cytotoxic venom, destroying local tissue, while releasing the tourniquet floods the body with a lethal, concentrated dose. Pressure immobilization is sometimes used for neurotoxic snakes, but a blanket tourniquet recommendation is catastrophically harmful.
