fuller's earth

 [ful´erz erth]
an impure aluminum silicate that has decolorizing and purifying properties. It is an absorbent used in the management of paraquat poisoning; the mode of action is by tightly binding paraquat to the clay in the formulation, which takes place in the gastrointestinal tract and facilitates elimination in the feces.

1. an amorphous variety of kaolin of varying composition, containing an aluminum magnesium silicate. The name is derived from an ancient process of cleansing or "fulling" wool to remove the oil and dirt particles with a water slurry of earth or clay.
2. a refined clay sometimes used as a dusting powder or applied moistened with water as a form of poultice. Currently refers to any clay that can be used for the purpose of decolorizing in oil refining.
