According to the public health network, the way to stimulate defecation with cotton swab dipped in sesame oil is to use a cotton ball stick, dip a small amount of sesame oil and smear it on the anus or inside the anus, which can play a role in lubrication and moisturizing. If you don't have sesame oil, you can use kaisailu, because kaisailu can soften the stool and stimulate the intestinal wall, thus reflexively causing the defecation reaction, so that the stool is excreted.

There are two kinds of common Kaisailu preparations [2], one is glycerol preparation, and the other is mannitol and magnesium sulfate preparation. The components of the two preparations are different, but the principle is basically the same. They all use high concentration of glycerol or sorbitol, that is, hyperosmotic action, to soften stool, stimulate intestinal wall and reflexively cause defecation reaction. In addition, they also have a lubricating effect, which can make the stool easily discharged. Sesame oil and kaisailu are known to have the same lubricating effect, so kaisailu can be used instead of sesame oil.
