This kind of wild vegetable has to lie on the surface of the water and pick as slippery as snot, but it has high nutritional value and is called the king of zinc.

When I was a child, I grew up in the countryside. At that time, the ingredients at home were relatively simple. After spring, my mother would always get some wild vegetables for us to eat. At that time, I always felt very delicious when I ate a new taste. Now although people also like to eat wild vegetables, but now the wild vegetables are not easy to find, especially some aquatic wild vegetables, with the pollution of river waters, less and less.

The wild vegetable to be mentioned today is called Brasenia schreberi, which is a kind of wild vegetable growing in water. What we eat is its tender stems and leaves, and we must pick those tender stems and leaves that have not yet opened. Brasenia schreberi can grow from April to October, during which time Brasenia schreberi can be picked. Because Brasenia schreberi grows rapidly, the tender stems should be picked every three to five days. If they are not picked in these days, the tender stems will be old and can no longer be eaten. We can only wait for the next wave to come out with new tender stems. The tender stems we usually eat are not yet open and curled.

The whole growth cycle of Brasenia schreberi has high requirements for water quality, because Brasenia schreberi can secrete a kind of snot-like colloid wrapped around Brasenia schreberi in clean water environment. If the water quality of Brasenia schreberi growing is polluted, Brasenia schreberi cannot secrete this colloid, then Brasenia schreberi will rot and die in water. Therefore, we usually eat Brasenia schreberi very slippery, because the surface of Brasenia schreberi is wrapped in this layer of colloid, especially in the tender stem, the colloid content is the most abundant, so it tastes very good. This kind of gel-wrapped Brasenia schreberi is different from other wild vegetables in taste and taste, which is one of the reasons why many people like to eat Brasenia schreberi.

In addition to good taste, its nutritional value is also very high. It grows in clean water environment for a long time and absorbs nutrients in water. The content of colloidal protein and various vitamins in Brasenia schreberi is very high. Moreover, Brasenia schreberi not only has edible value, but also has great medicinal value, with diuretic and detoxification effects. In addition, the zinc content in Brasenia schreberi is very high, which can be said to be the crown of wild vegetables. It is known as "zinc king" in folk, especially suitable for children to eat. Because zinc promotes intellectual development, eating Brasenia schreberi is good for children's intellectual development.

At present, many people are very popular with Brasenia schreberi because of its taste and value. However, due to the pollution of water quality and environment, the number of wild Brasenia schreberi is becoming less and less. Most of the Brasenia schreberi on the market is artificially planted, and its nutrition is also very good. Picking Brasenia schreberi is a technical job. It is very hard to pick it on the water surface.
