Interactions of Clay and Clay Minerals with the Human Health

  • Chapter
  • First Online:
Minerals latu sensu and Human Health

Abstract

This chapter is initiated with the record and discussion of the diverse uses of healing clay, both for internal applications involving geophagy and edible clay and for external or topical applications involving the practices called mud therapy and pelotherapy. The etiology and health consequence (benefits, risks, and mechanisms of action) of edible clay are discussed. Distinction is made between geophagy and pica. Distinction is made too between mud and peloid materials, characterized in terms of diversity and typology. One type of peloid, the designed and engineered peloid, is enhanced, since its simple composition, manipulation, and modification allow a better understanding of its medical or cosmetic performance. Peloid’s function, benefits, risks, and mechanisms of action and edible clay mechanisms of action are reported and discussed. Databases of publications on medical and cosmetic pelotherapy are reported. The role of clay minerals in biocomposites, and in controlled drug delivery systems for pharmaceutical and medical applications, the case of halloysite nanotubes, is discussed. The bactericidal activity of some minerals is reported and explained. The chapter ends identifying and discussing diseases whose etiology is attributed to clay such as podoconiosis, Mseleni joint’s disease, Kashin-Beck’s disease, and Keshan’s disease, as well as other adverse effects caused by clay and clay minerals.
