Now many of us have left our hometown villages and come to the city to live or develop. Thinking back to the interesting creatures you saw in the rural fields, you are still impressed with them, let's take a look at the introduction of leeches.
1. Leech: also known as locust, in most of the rivers and lakes on the mainland have distribution, there are more than 100 species, most of them in the wild to snails, plankton, insects, earthworms and so on for food. However, in recent years, due to the development of mainland urban construction and the irregular use of pesticides and fertilizers, they can no longer be seen in many water bodies.

Leeches actually have more advantages than disadvantages, they are our traditional Chinese medicine in ancient times, sun-dried leeches can be used to treat high blood pressure, stroke, bruises, anti-thrombosis, anti-coagulation, etc., live leeches at home and abroad are used to deal with congestion, blood breakage and so on. Because their wild population has decreased sharply in recent years, there are leech farms in many parts of the country for the supply of a huge market for leech medicinal materials, and there is still a gap in the market.
Treatment of live leeches is common
For Xiaobian, leeches were both afraid and curious about it when they were young, and the fear was that every time they randomly stirred up the water by the river, they would see them swimming in waves from different directions, afraid that they would bite people and suck blood. When I was a child, I saw many elders being bitten by leeches, and they used hot tongs or lighters to burn leeches to let it loose, and then I saw that the wound was bleeding continuously. Curious about it, when I was a child, I used to catch leeches with my friends to have all kinds of small tortures, hahaha, and it was also a childhood pleasure. Have you ever seen leeches? Is there anything in particular you would like to share?
In addition, it is a reminder that when traveling or playing in the wild, do not drink directly from the stream or river water, because there may be leeche eggs or small leeches in it. If, while drinking water, the leech enters the nasal cavity through the nose, or if the egg reaches a humid and warm environment in our human body, it will hatch in our body and suck our blood to grow. There have been many cases in China where tourists or local residents drink raw water, causing leeches to grow and destroy in our bodies, and even cause things.
In 2019, Xiao Wei's nose in Guilin, Guangxi, frequently bled, and when he went to the hospital to check it, he found that a 2.5 cm long leech had grown in the nasal cavity. According to Xiao Wei, after she was busy in the mountains before, she would wash her face or drink mountain spring water with mountain spring water, and the doctor judged that this was the source of leeches.
Remove the leeches
Therefore, when outdoor activities, do not try to drink directly from the stream or mountain spring water, in addition to leeches, there may be schistosomiasis, other eggs and so on. The above is all content, welcome to comment and suggest.
