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, the lobotropin in them increases greatly, and the lobotropin is not removed or destroyed when cooking, and poisoning occurs after consumption. After poisoning, there is a burning sensation and pain in the upper abdomen, followed by dry throat, nausea, vomiting, abdominal education, diarrhea, and even fever, respiratory distress, convulsions and coma, and can also cause intestinal cyanosis, mostly due to respiratory central paralysis and death. So, what are the ways to prevent itching in the throat and mouth caused by potato poisoning? The following is a brief introduction to the prevention methods: 1, a little sprouted potatoes have not deteriorated, you can gouge out the sprouting eyes thoroughly, the skin and flesh of the purple part of the trimming, and then soak in cold water for 30 to 60 minutes, so that the residual toxins dissolved in the water, and then wash. Add vinegar when cooking and cook fully before eating. Heat and vinegar can accelerate the decomposition of lobelia and make it non-toxic. But the above practices do not apply to sprouting too much and most of the flesh of the potatoes turned purple, these potatoes even processing can not guarantee non-toxic. 2, the vast majority of potato poisoning occurs in the spring and early summer season, the reason is that the spring is wet and warm, poor storage of potatoes, easy to cause sprouting. Therefore, to strengthen the storage of potatoes to prevent sprouting is the fundamental guarantee to prevent poisoning. 3, potatoes should be stored at low temperatures, no direct sunlight to prevent sprouting; do not eat too many sprouts, black and green skin of potatoes to prevent food poisoning; sprouts less potatoes, eat to thoroughly dig out the buds and eyes, and the skin around the eye of the buds to dig off part of the potatoes should not be fried shreds or fried slices to eat, can be braised, stewed, boiled to eat, cooking can add some vinegar to accelerate the decomposition of lobeline.
