When it comes to the use of leek roots, I have personal experience. When I was a child, I was weak, especially in love sweating at night. I just sweated like I was in an ice cave. I feel hot when I don't sweat, but I don't feel cold when I sweat. Later, I heard from the old man in the village that I steamed leek roots with a little lean meat, and then ate leek roots with meat and soup, and it would be fine in less than a month. Therefore, leek root has obvious effect on sweaty people.
