Soapberries are a natural alternative to traditional laundry detergent and fabric softener.  'That Red House' soapberries are they only ones on the market that are 'Certified Organic'. They are often called 'soapnuts', but they are not nuts at all. They are in fact a fruit!  The shell of the fruit is collected, dried and packed for use. The shell is exceptionally high in 'saponin' which is nature's soap. This saponin reduces the surface tension of the water to remove dirt and leave fabrics, soft and clean.
