1. Early Tourniquet: Immediately tie a bandage 5–10 cm from the wound, closer to the heart. Loosen the bandage every 15–30 minutes for about 1–2 minutes each time.
2. Rinse the Wound: After applying the tourniquet, rinse the wound immediately. You may use saline solution, hydrogen peroxide, soapy water, or 0.1% potassium permanganate solution. In the wild, if none of these are available, place the injured limb in a stream or pond to rinse.
3. Wound Expansion for Toxin Drainage: Using a scalpel or other sterilized small knife, make a longitudinal or “+” shaped incision along the fang marks, about 1–2 cm long and deep enough to reach the subcutaneous layer. Then, use both hands to repeatedly squeeze from the part closer to the heart toward the part farther away and from the surrounding area toward the wound to drain the toxic blood.
4. Neutralize the Snake Venom: You can use the match burning method—pile 4–6 match heads on the wound and ignite them, repeating 3–5 times. This method is suitable for snake bites with shallow fang marks or wounds that continue bleeding and should not be expanded.
5. Emergency Medication: Take snakebite medicine immediately after the injury, doubling the initial dose. If no medicine is available, you can use fresh herbs such as about 120 grams of Herba Lobeliae Chinensis, wash it, mash it with cold water, take the juice orally, and apply the residue externally to the wound.
