There is a wild plant called Soapwort and as its name suggests, it contains Saponins. Saponins are named from the Latin word Sapo which means soap. You would be able to obtain a lather for washing with this plant. There are other plants too, that contain saponins, so when out in the country near to water you will be able to experiment with the plants that are in the area. Be careful though that you're not handling poisonous plants. Kenneth Eames.
