Common soapwort is one of the richest plants in saponins, therefore it has been used to wash clothes and wool. People placed a bunch of rhizomes in a bowl with water and let the clothes soak overnight. The next day, they rinsed it and the clothes were clean because the foam generated by the saponins of this plant removed the dirtiness. In fact, it is also known as Lanari because the same procedure was used to wash the wool.
