This herb is also used in homeopathic medicines. I think every plant has some medicinal properties. We don't know much about many plant species but it doesn't mean that they are useless. My grandmother used to treat people with herbs and plant extract as doctors were not available in our areas. Many village folks in rural areas still use herbs to treat patients. Once, I fell down and my head was cut. There were profound bleeding. My grandmother applied crushed leaves of some plant over my head and bleeding stopped. When I woke up in the morning the wound had heeled miraculously as if it was not there.
