wula sedge (Carex meyeriana)

Ursula is a perennial herb. That is, one of the famous "Three Treasures of Kanto" has the function of keeping warm and cold, and people in mountainous areas love it very much. On the surface, Ursula grass looks ordinary, with slender stems and leaves, green, clusters of flowers and green-brown spikes. However, for hundreds of years, this kind of ordinary grass has been closely related to the people's life in Changbai Mountain and has become an indispensable necessity. Every autumn, people go to the mountains to cut Ursula grass, dry it and store it, and floc it into shoes in winter to avoid frostbite on their feet. The winter temperature in northeast China is low, the lowest can reach MINUS 40℃ and 50℃, so it is difficult for ordinary cotton shoes to keep out the cold. And the common people use the wula made of animal skins, and then put the wula grass on it, so the feet will not freeze in the cold weather. Ursula grass should be beaten with a wooden stick before use, so that it will not hurt your feet after being softened. The winter time in Changbai Mountain is long, and cold protection is a big problem that is widely known. The working people work in the wild every day, and the relationship between Ursula and people is extraordinary. This is the main reason why people call it one of the three treasures of Kanto. There are many wild grasses in Northeast China, which are similar in shape to Ursula grass, but only Ursula grass has the best warmth retention performance. This is the experience gained by our ancestors through personal practice from a variety of grasses. Who was the first to know the function of Urtica uralensis Fisch has no textual research. It is still a mystery why Ursula has an extraordinary warm-keeping effect. It is said that Ursula grass can now be exported to earn foreign exchange. It seems that Ursula grass is still a treasure.
