Why a tight bandage is tied above a snake bite?

A tight bandage is applied above a snake bite to help slow the spread of venom through the bloodstream. This technique, known as a constricting bandage, aims to restrict lymphatic flow and can potentially delay systemic effects of the venom. However, it is important to use this method cautiously to avoid restricting blood flow, which can cause further tissue damage. Immediate medical attention is still essential for effective treatment.
