When potatoes germinate, they produce a toxin called solanine. Good quality potatoes only contain 100 mg of solanine per 100 g, while solanine in green, germinated and rotten potatoes can be increased by more than 50 times. Eating a very small amount of Solanum nigrum is not necessarily harmful to human body, but if you eat 200 mg of Solanum nigrum (about half a dozen potatoes that have turned green and sprouted) at a time, it will take 15 to 3 hours to get sick. The earliest symptoms are itchy mouth and throat, epigastric pain, nausea, vomiting and diarrhea. Those with mild symptoms will heal themselves after 1 ~ 2 hours through their own detoxification function. If you eat more than 300 ~ 400 mg of Solanum nigrum, the symptoms will be very serious, such as dehydration and repeated vomiting caused by rising body temperature, dilated pupils, fear of light, tinnitus and so on.

Attention must be paid to prevent potato solanine poisoning. * Don't eat immature green potatoes. * Slightly germinated and bluish parts and rotten parts on potatoes should be thoroughly removed. If the blue area of potatoes is large and there are many sprouted parts, they should be thrown away. * Cut peeled potatoes into small pieces and soak them in cold water for more than half an hour to make the remaining solanine dissolve in water. * Using the weak alkalinity of Solanum nigrum, adding proper amount of rice vinegar when cooking potatoes, and decomposing Solanum nigrum by using the acidity of vinegar can play a detoxification role. * Boiled potatoes should be crispy and thoroughly burned, and solanine can be partially decomposed by using high temperature for a long time. If you feel a little numb in your mouth when eating potatoes, it means that potatoes still contain more solanine, so you should stop eating them immediately to prevent poisoning. It has been reported that if pregnant women eat too much solanine, it may lead to fetal malformation, so pregnant women should be especially careful.
