Itching in the throat and mouth is one of the symptoms of potato poisoning from eating sprouted potatoes. The consumption of large quantities of immature or sprouted potatoes can cause acute poisoning. When potatoes are sprouted or partially green, there is a large increase in lobotropin, which is not removed or destroyed when cooking, and poisoning occurs after consumption. Potatoes and its toxic components for lobotoxin, also known as potato toxin, is a weak alkaline biogenic glycosides, soluble in water, easily decomposed in acetic acid, high heat, boiled through can be detoxified. Each 100 grams of potatoes contain only 5 to 10 mg of lobotoxin; sprouted potatoes or immature, green and purple skin of potatoes containing lobotoxin increased by several times or even tens of times. Loncomannin has corrosive, hemolytic, and paralyzing effect on the motor and respiratory centers. Acute sprouted potato poisoning usually develops tens of minutes to hours after eating. First there is a throat and mouth tingling or burning sensation, followed by nausea, vomiting, abdominal pain, diarrhea and other symptoms. The lighter ones heal themselves in 1 to 2 days; the heavier ones have water loss and electrolyte disorders due to violent vomiting and a drop in blood pressure; patients with severe poisoning have coma and convulsions, and finally death due to respiratory central paralysis.
