1. After the potato germinates, the bud hole and embryo of the potato will contain a toxin called "Solanum nigrum" or "potato essence", which is toxic to human body. So if you find that the potatoes you bought are sprouting, you must not eat them directly without taking any measures, otherwise poisoning may occur.

2. The main hazard of Solanum nigrum L. is acute poisoning, with symptoms of dizziness, dizziness, nausea, hot throat and dry tongue, followed by vomiting, abdominal pain, diarrhea, heartbeat, palpitation and headache. A few people will have sweating and diarrhea.

3. In case of potato poisoning, you should be sent to hospital immediately. More importantly, you should take daily precautions. If you encounter sprouted potatoes in your daily life, you should choose to throw them away. However, if the germination of potatoes is not serious, they can still be preserved, because solanine is unevenly distributed in potatoes, and the content in epidermis and buds is the highest. You can peel the potatoes and dig out 1~2 around the sprouting point.
