Autocannibalism

Autocannibalism, also known as self-cannibalism and autosarcophagy, is the practice of eating parts of one's own body. Generally, only the consumption of flesh (including organ meat such as heart or liver) by an individual of the same species is considered cannibalism. In line with this usage, self-cannibalism means the consumption of flesh from one's own body. While some texts use this strict definition, others use the term autocannibalism in a wider sense that includes the consumption of hair or nails from one's own body.
