First, induce vomiting: If you take it within1~ 2 hours, you can use the method of inducing vomiting. Immediately take 20g of salt and add 200ml of boiling water to dissolve it, and then drink it once after cooling. If you don't vomit, you can drink it several times to quickly promote vomiting. You can also mash fresh ginger 100g to get juice and take it with 200ml warm water. If you eat bad meat food, you can take ten drops of water to promote rapid vomiting. Some patients can also use chopsticks, fingers or goose feathers to stimulate the throat and cause vomiting.
Second, catharsis: If the patient takes food for a long time, generally more than 2 ~ 3 hours, and the spirit is good, he can take some laxatives to urge the poisoned food to be excreted as soon as possible. Generally, rhubarb 30g is decocted once, and 20g of Sodium Sulfate can be selected for elderly patients, which can relieve diarrhea by taking it with boiled water. For the elderly who are in good health, senna leaf 15g can also be decocted once, or boiled water can also be used to induce diarrhea.
Third, detoxification: if it is food poisoning caused by eating spoiled fish, shrimp, crabs, etc., it is advisable to add 200ml of water to vinegar 100ml and take it once after dilution. In addition, 30g of Perilla frutescens and raw licorice 10g can be decocted once. If you eat spoiled drinks or preservatives by mistake, the best first aid method is to fill them with fresh milk or other protein-containing drinks.
