Tools: clear water, tweezers, iodophor, fresh purslane.

1, avoid scratching. Insects can cause severe itching, tingling, burning, etc. after contacting the skin. Scratching should be avoided to avoid abscess.

2. Wash the affected area with weak alkaline solution such as clear water or soapy water.

3, remove local residual stinger. If there are hairs and stingers left in the area, try to remove them with transparent tape or clean tweezers, rinse them again and disinfect them with iodophor.

4, local medication. Mashing fresh purslane and applying it to the affected area can help relieve the discomfort symptoms, which can usually be gradually relieved in about 1 week. If you can't relieve or remove the burr, or have severe redness, rash, severe pain and other symptoms, you need to see a doctor.
