Whether or not potato poisoning can be cured on its own depends on the amount of poisonous potatoes ingested and the severity of the poisoning symptoms. In the case of very mild poisoning caused by ingesting very few poisonous potatoes, the patient does not need to be treated but can heal by self-medication. Patients can heal after 1-2 days by taking proper rest, drinking more water and eating light soups and foods. However, if the symptoms of potato poisoning are more serious, it is best to go to the hospital for careful examination and symptomatic treatment. Because potatoes contain lobotoxin, which can cause hemolytic poisoning and damage the central nervous system, and have a strong local corrosive or stimulating effect, they can cause very serious symptoms of poisoning and should be treated promptly in a hospital.
