Nightshades contain a chemical alkaloid called solanine which can trigger pain
According to another hypothesis, proposed by Paul Sherman, eating clay may help remove toxic chemicals found in some plants, such as solanine misspelled as solanin in Nature in potatoes.
The green is chlorophyll but can indicate the presence of solanine which is a toxic chemical.
The most dangerous plants contain one of these three chemicals — solanine, grayanotoxins, and cardiac glycosides.
He did pretty well too until he died after he ate the one thing he knew he shouldn't have - potato seeds (actually the fruit that houses them), which contained the toxic alkaloid solanine.
The green itself is harmless chlorophyll, but it can sometimes be associated with the development of solanine, a pretty nasty toxin found in members of the nightshade family, including potatoes.
These include the solanine, arsenic, and chaconine in potatoes, the hydrogen cyanide in lima beans, and the hallucinogenic compound myristicin found in nutmeg, black pepper, and carrots.
Most commercial varieties contain 2 to 15 milligrams of solanine and chaconine per quarter-pound 100 grams of potato.
