When potatoes were first introduced to France, they were not popularized for a long time, because there was no scientific research on the nutritional components of potatoes, many people thought it was harmful to health, and some people even arbitrarily said that planting potatoes would make the originally soft and fertile soil barren. Ai Rui, a famous French agronomist, doesn't think so, but the popularization is opposed by people.
It is said that some Europeans used to eat the bitter and poisonous green fruit from the seedlings of the horse bell, and were poisoned by it, so they also called the potato "the devil's apple". Moreover, French farmers at that time were not interested in high-yield and disease-resistant potatoes, and the publicity effect was very small. Because of these two reasons, no one dared to grow potatoes at first.
When potatoes were first introduced to Europe, Europeans in the 17 and 18 centuries were both curious and afraid of this round and non-round thing, and there were many different opinions about potatoes. Some people think it is an aphrodisiac; Others think that potatoes can cause fever, leprosy and tuberculosis. The conservative Orthodox godfather even accused potatoes of being the embodiment of evil.
Wild potatoes are highly toxic, and solanine poisoning can lead to headache, diarrhea, convulsions, coma and even death. Its variety is special and rare. At first, because potato is not a seed plant, it is different from the original crops in Europe. European farmers are completely uninterested in this exotic crop, and even think it is the cause of fever and aphrodisiac food.
