Potatoes can't be eaten even if they germinate slightly, because there are more or less substances harmful to the body when they germinate, such as solanine, which will be harmful to the health after entering the body. Mild cases may cause gastrointestinal reactions, such as nausea, vomiting, abdominal pain, bloating and diarrhea. If the intake of Solanum nigrum is too high, it may affect the nervous system and cause unconsciousness and coma. If it is serious, it may cause allergic reactions, ranging from itchy skin to anaphylactic shock and asthma. Therefore, potatoes with slight germination should not be eaten.
