According to legend, once upon a time, under Mount Emei lived a young loving couple, a man cultivating and weaving women, and their lives were very happy. Who knew that one day, her husband suddenly had pain under his ribs, like a knife pricking a needle, and soon he died of pain.
The wife is very sad, must ask the doctor to find out the cause of death, the doctor according to the condition of the deceased and the pain of the site, caesarean section, found that the deceased gallbladder has a stone. The wife took this stone and said sadly, "It is this merciless stone that has torn apart our husband and wife, and it has caused me so much pain." I wanted to break it up and throw it away, but on second thought, it was better to keep it as a souvenir, so she woven a small net pocket with red and green silk thread, put the stone inside, hung it around her neck all day, worked, and did not take it down when she slept.
Coincidentally, one autumn, she went up the mountain to cut the grass, cut a large coffin and went home, and when she got home, she suddenly found that the stone hanging on her chest had been half dissolved, and then this matter was heard by a doctor, who came to her door and said to her: "There is a kind of grass in the grass you cut that day that can turn stones, you take me up the mountain to find that kind of grass." Unexpectedly, the grass in the field had been cut, and the doctor made marks on the ground.
The following autumn, the doctor went up the hill with the woman again and cut all the grass from the ground. Then separated by class, and then put the stone on each kind of grass successively to test, and finally found the kind of grass that can turn stones, the doctor said happily: "This gallstone patient has been saved." Because the leaves of this grass are round, much like money, and it can dissolve the stones in the gallbladder, the value is more valuable than money, so it is called "money grass".
