Soap nuts are found in both the eastern and western hemispheres, but are native to India and Nepal. They have recently become a popular environmentally friendly alternative to chemical detergent, and are a gentle option for those with allergies to chemicals in regular detergents. They have traditionally been used as an expectorant, and in Ayurvedic medicine as a treatment for eczema and psoriasis. Soap nuts contain saponin, a natural detergent. The soap nut shell absorbs water and releases the saponins which circulate as a natural surfactant in the wash water, freeing dirt, grime, and oils from clothing.
