It's complicated to say, potato germination will produce a toxin called solanine (also 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, diarrhea and other symptoms.

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 body temperature rising and dehydration, repeated vomiting, pupil dilation, photophobia, tinnitus, convulsions, dyspnea and blood pressure drop. Few people will die of respiratory paralysis. Therefore, patients with severe symptoms should be sent to the hospital as soon as possible.
