Interactions of Clay and Clay Minerals with the Human Health
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.
Efficacy of oral iron therapy in geophagic women with iron deficiency anaemia residing in Botshabelo, South Africa
The challenge for the current study was the paucity of information on the exact prevalence of geophagia on the study’s target population, non-pregnant females.
Potential health risk assessment of toxic metals contamination in clay eaten as pica (geophagia) among pregnant women of Ho in the Volta Region of Ghana
It is not safe for pregnant women to consume clay as pica since these toxic elements may cause detrimental effects on the foetus of the unborn child and there is the likelihood of posing adverse health problems when Anfoega which is sited in the Volta region of Ghana is consumed.

This paper pretends to review historical data, basic concepts and functions, as well as benefits and risks of the use of healing clays, in general, for therapeutic and cosmetic purposes, and of edible clays for therapeutic purposes.
Termites and savannas – an overview on history and recent scientific progress with particular respect to West Africa and to the genus Macrotermes
Insbesondere in Savannen fungieren Termiten als Okosytem-Ingenieure und stellen damit eine okologische Schlusselgruppe dar. Besonders wichtig fur Zusammensetzung und Struktur der Savannenvegetation
Evaluation of geochemical characteristics and health effects of some geophagic clays southern Nigeria
The high concentrations of the PHEs may be responsible for or contribute in part to the prevalence of hypertension, cardiac failures and gastrointestinal problems within the study areas, and the toxic trace element concentrations and significant quartz content will most likely mask the beneficial effects of such kaolinite.
Naturotherapies Based on Minerals
Since the antiquity, and on an empirical basis, man has accumulated experience on the benefits and risks of minerals (such as, special clay, mud and sand) and other mineral resources (such as, salt,
Haematological and iron status of Qwa Qwa women in South Africa who ingest clays
The aim of was to investigate the link between iron deficiency anaemia and geophagia in QwaQwa women since this link has not been investigated in South Africa, and to determine the prevalence of iron deficit anaemia.

The mineralogical and geochemical composition of geophagical materials collected from Uganda are reported, and the potential of such soils in supplying iron to the Geophagist is indicated.
Geophagy among school children in Western Kenya
The prevalence of geophagy decreased with age for both sexes up to age 15, then remained stable for girls between 15 and 18 years but continued to decrease for boys in that age range.

Formation of cave salts and utilization by elephants in the Mount Elgon region, Kenya
Abstract Herbivores such as the African elephant receive most of their nutrient uptake through digested vegetation or water. When these nutrient sources do not fulfil dietary requirements, eating and

The role of geochemistry in environmental and epidemiological studies in developing countries: a review
Abstract Concern over the effects of chemicals in the environment on the health of man and animals is growing as rapid economic and population growth extends such problems as land degradation,
