Self-cannibalism

Practice of eating oneself

Self-cannibalism is the practice of eating parts of one's own body, also called autocannibalism or autosarcophagy. Generally, only the consumption of flesh 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.
