This weed is called the flying centipede, which can drill into cracks and cause houses to collapse, but some people regard it as a treasure.

In the countryside, there is no shortage of wild flowers and weeds. For most farmers, weeds are basically useless. Growing in the fields also hinders the growth of crops. The most worry-free way is to pull it out or use herbicides to eliminate it. But as the saying goes, if you don't know grass, knowing it is treasure. If you know its real use, you won't underestimate it. In rural areas all over the country, there is a very characteristic weed that likes to climb high and grows specially on all kinds of walls. It can climb as high as the building is. This weed has a nickname, "Flying centipede". Most people have seen it.

In fact, the name Feitian centipede is very appropriate, because like the centipede, it not only has many feet, but also has a certain degree of toxicity. Its "foot" is the root and sucker on the rhizome, which has a strong adsorption capacity and can be adsorbed on the smooth cement wall. If there is a crack in the wall, its root will take the opportunity to go deep into the crack and slowly enlarge the gap. If it is not repaired in time, it may cause the wall to crack and the house to collapse. In addition, its roots also secrete an acidic substance, which has a certain corrosive effect on limestone and, of course, is toxic to the human body.

After seeing so much, many people have recognized that this "flying centipede" is actually what we often call "creeper". I remember learning a text when I was a child, Mr. Ye Shengtao wrote "the feet of Parthenocissus", which spoke highly of Parthenocissus: "A gust of wind blows, the leaves of a wall ripple, good to see." What we are talking about here is the greening and covering function of Parthenocissus, because its leaves are large and dense, and the growing season is mainly when the weather is hot in spring and summer. Covering on the wall can effectively block the scorching sun and reduce the indoor temperature. At the same time, it also reduces noise and absorbs dust. Therefore, the figure of Parthenocissus can be seen on the green walls of many cities.

But as mentioned earlier, Parthenocissus will drill into the cracks in the wall to destroy the wall, why would some people regard it as a treasure and use it for greening? In fact, this worry is superfluous, first of all, Parthenocissus is not an evergreen plant, it will wither in autumn and winter, you can observe whether there are cracks in the wall, if so, even if there is no Parthenocissus, it also needs timely repair. Secondly, now the houses are built more solidly, unlike in the past are dirt houses, so there is no need to worry about the walls will be damaged.

Finally, the rhizome of Parthenocissus is still a kind of traditional Chinese medicine, which has the effect of promoting blood circulation and dredging collaterals, dispelling wind and relieving pain. it is often used by folk to soak wine and apply externally to treat rheumatic arthralgia, fall injury and other diseases. As it has a certain degree of toxicity, it is generally not recommended for internal use. If you need to use it, please consult your doctor.
