If it is only germinated and cut off, it can be eaten. The toxic alkaloids contained in germinated potatoes are more important. Solanum nigrum toxin mainly causes gastrointestinal injury, paralysis of respiratory center and motor center by inhibiting the activity of cholinesterase, and can also cause brain edema and gastroenteritis.

If the potato only has one bud, it is too wasteful to throw away the whole potato for one bud. Then you can remove the long bud. When the potato just germinates or the bud is not big enough, you can dig out the bud and the bud eye, and the rest can still be eaten.

Because the toxin at this time is still concentrated in the bud eye and the nearby part, the toxin has not spread. In general, if you don't eat enough potatoes to cause food poisoning, there will be no problem.

However, if the surface of the potato is moldy and blue, or a potato has several buds, it should be thrown away without hesitation. Even if the bud of this potato is cut off, there is no poisoning after eating it, and there is little nutrition left, and the taste is also very poor.
