Imagine a detergent that is completely natural, with no animal ingredients, capable of washing your clothes, washing your dishes and cleaning the house. Your dream will come true with soap nuts which were used as a detergent for centuries.
Soap nuts are actually berries (also known as a soap berry) that grow on the Sapindus tree, an evergreen tree belonging to the Sapindaceae family. Sapindus are common in India and Nepal mostly but also in Southern Asia and in the USA. Nuts contain saponins which produce a foam when shaken in liquid, just like regular soap.
