After ingesting "coarse salt" and experiencing poisoning:1. Immediately induce vomiting to expel the barium compound,drink 20-30g of sodium sulfate and take plenty of water to convert the toxic substance into soluble sulfatesodium,then wash the stomach with a 2-5% sodium sulfate solution or warm water until clear.2. After gastric lavage, orally consume or inject 10-30g of sodium sulfate in 200-300ml of water one hour later and repeat if necessary.

3. For severe cases, slowly administer 1% sodium sulfate 10ml intravenously every 30 minutes until symptoms subside.
