The Use of Earth and Clays
Earths and clays may have provided prehistoric peoples with some of their first medicines. This is related to geophagy, which is extremely widespread among animals in the wild as well as among domesticated animals. In particular, geophagy is widespread among contemporary non-human primates. Also, early humans could have learned about the use of various healing clays by observing animal behaviour. Such clay is used both internally and externally, such as for treating wounds, and after surgery (see below). Geophagy, and the external use of clay are both still quite widespread among aboriginal peoples around the world, as well as among pre-industrial populations.
