Both white vinegar and soapy water can be used for jellyfish stings, and both have different uses for emergency treatment when outdoors. White vinegar has the ability to reduce the activity of venomous sting cells and has an analgesic effect. You can use white vinegar to rinse the wound first, and then use tweezers and other external objects to treat the tentacle residue cleanly, and then you can apply soapy water to the wound. Soapy water is an alkaline solution, while jellyfish venom is an acidic solution, using soapy water can neutralize some of the toxins and reduce the body’s absorption of the toxins. After emergency treatment, you should go to the hospital in time for more specialized examination and treatment, and you can use relevant medication under the guidance of your doctor. Stings vary from person to person. If the situation is serious, it is recommended that you can call the emergency number or go to a nearby hospital for treatment at the same time as the emergency treatment.
