This weed is called Seven Star Sword. It used to be a cure for the poor. Now it's 18 yuan a catty. It's a rare commodity.

Friends living in the countryside, especially some elderly farmers, love many weeds very much, because many weeds are of great use. I remember living in the rural and mountainous areas when I was a child. At that time, my family was still relatively poor, and when I was sick, I never went to the hospital. Instead, my parents went to the mountains to pick some weeds to boil and drink, and then the illness was cured. So at that time, many farmers living near the mountains regarded the weeds in the mountains as medicine for the poor. Below, the author will introduce to you such a kind of mountain weeds, which is also a weed that the author has used before.

In the mountains in the countryside, there is such a strange weed whose big leaves look like a long sword, and this weed usually grows only on damp stone walls or rock walls in deep mountains and old forests, so it is generally known only to farmers who live in mountainous areas. many peasant friends call this weed "seven-star sword". In fact, the original name of this weed is "Jiangnan star fern". In some places, it is also called piece grass, tile Reed, Dryopteris flexneri, seven-star Phoenix tail grass, big-leaf bone row grass.

When it comes to Jiangnan star fern, many friends may not be familiar with it. except for the older generation of peasant friends, in the past, friends living in rural and mountainous areas were relatively poor and could not afford to go to the hospital when they were ill. therefore, they can only go to the mountains to find some weeds to treat the disease, and Jiangnan star fern is a commonly used folk herb, it is a perennial evergreen weed. Therefore, no matter what season you go to the mountains, you can pick it. It can be said that it saved a lot of people's lives and made many poor people love it very much.

So what is the specific medicinal value of Jiangnan star fern? The author has also consulted the relevant data. according to the National Compendium of Chinese Herbal Medicine, the whole grass and rhizome of Dryopteris in the south of the Yangtze River can be used as medicine, its taste is slightly bitter and cool, and it has the effect of clearing heat and dampness, cooling blood and detoxification. Can be used to treat influenza, asthma, bronchitis, jaundice, infantile convulsions, tuberculosis cough, rheumatoid arthritis, gonorrhea, urinary calculi, dysentery, leucorrhea, snakeworm bites, nameless swelling poison, poison carbuncle, traumatic bleeding, hot rain, adverse urination, rheumatism pain, broken bones and so on as many as a dozen kinds of symptoms, you can imagine how high its value, so it is reasonable for farmers to like it.

It is precisely because the Jiangnan star fern has such a high medicinal value that now many farmers specialize in planting it to sell it. According to the villagers who grow the Jiangnan star fern in the village, because there is basically no such weed in the city, it also makes it quite valuable. About 18 yuan per jin, it is also a kind of rare goods, and there are also many farmers who grow Jiangnan star fern to get rich. So despite the strange growth of this weed, it is still very precious.
