Inferred from the painting style of these patterns, the cultivation history of potato in South America can be traced back to at least 2000 ~ 2800 BC. Indians have lived in cold high-altitude mountainous areas for a long time. Potatoes are a kind of plants that like cold and are very suitable for growing in this climate.

Potatoes can also cure diseases.

Potatoes are good, but you can't eat them indiscriminately. Potatoes contain an alkaloid called solanine, which can cause paralysis of motor and respiratory centers, leading to poisoning. In general, the content of solanine is very low, and once potatoes germinate or turn green, solanine will increase greatly, so it is very unsafe to eat such potatoes. Now is the season when potatoes are on the market, and potato poisoning is easy to occur, so be careful not to buy sprouted potatoes when buying, and try to eat them while buying.
