The wild vegetables with high oxalic acid are: horse tooth, sour touch and wild leek. These three kinds of wild vegetables must be cooked thoroughly before eating, otherwise they are prone to oxalic acid poisoning. When I was a child, my mother often picked some wild vegetables in the field. Every time I picked wild vegetables, my mother told us not to cook them. When she cooked them herself, she said that wild vegetables were not handled well and would be poisoned after eating them. In fact, we don't know why they were poisoned. Now we know that the reason why they are easily poisoned is because of the high oxalic acid content. Let me talk about the wild vegetables with high oxalic acid that we often eat.

Horse tooth is one of the common wild vegetables in rural areas, whether it is in the wild, vegetable fields or fields. In summer, you will basically pick one and eat it cold or stir-fry at home. The taste of horse teeth is sour, so the more you eat, the more you want to eat, and the more you eat, the more appetizing you are. However, although it is delicious, it must be boiled with clear water, and it should be cooked for a while, and it can only be eaten when it is cooked thoroughly. Moreover, it is not suitable for the elderly and children, because its oxalic acid content is too high, so it will affect the calcium absorption of the human body, while others should eat less. After all, eating too much oxalic acid is easy to be poisoned.

Sour touch is also wild spinach. Although it is common in rural areas, it is not eaten in many places, because the taste of sour touch is as sour as its name. This kind of acid is actually because it contains a lot of oxalic acid. However, although the content of oxalic acid is high, it is also rich in vitamins and medicinal value, so the nutritional value is still very high in general. The eating methods of sour touch are: cold salad, fried eggs and boiled soup, but you can't eat too much, otherwise it will easily cause oxalic acid poisoning.

Wild leek Wild leek is very fragrant, and it is also called wild onion in some places. It is very delicious to fry eggs with it, so every time wild leek grows, many people will pull it home in large quantities to eat. In fact, you can't eat more wild leeks, because wild leeks are not only high in oxalic acid, but also high in crude fiber, so they are so fragrant, and after high oxalic acid is combined with calcium in the human body, it may cause stones, so people with stones must not eat wild leeks. The most common way to eat wild leek is fried eggs and pancakes, so the way to eat wild leek is also very convenient.
