What kind of grass is immortal grass? Knowing this, you won't be mistaken for weeds.

What grass is grass? Here, we can clearly answer that the "artifact" of burning grass, which looks appetizing and can cool down and relieve summer heat, is really made of grass, and this kind of grass is very common, and there are many around us, but many people often regard it as a weed.

Many people find it hard to understand why grass is related to grass because it looks like jelly. Whether you admit it or not, it is made of a plant called Cao Xian.

According to legend, there was a place in the south of ancient times. It was very hot in summer, and farmers had to work in the scorching sun every day, so many people often suffered from heatstroke. A fairy saw that the people were overworked and told the farmers that there was a grass in the mountains, and boiling water with it could cool down and relieve the heat. According to the immortal's instructions, the people used it to boil water to drink according to his practice, which was really a summer heat to cool down. From then on, people called this grass "Cao Xian", and the food obtained by boiling water with it was called "Cao Xian bean jelly".

This plant is not very special, but it is very common and distributed in Guangdong, Guangxi, Fujian, Hunan and other provinces in the south. It's a herb of Labiatae, and it looks like mint. Because it can make Xiancao blossom, it is also called "Xiancao" among the people. It has been planted in some places in the south for hundreds of years and has become an important cash crop.
