The medical term [epistaxis] refers to a “nose bleed”.
It is considered to be a Modern Latin term that originates from the Greek word [επίσταξη] (epístaxí). The word is composed of [επί] [epi-] meaning "on", "upon", or "above", and [στάζει] (stázei), meaning "in drops", "dripping".
The term was first used by Hippocrates, but only as [στάζει] , to denote dripping of the nose, and was later changed to [επίσταξη] to denote “dripping upon”. The term itself does not include or denote that the blood loss is from the nose, but its meaning has been implied and accepted for centuries. The plural form for epistaxis is epistaxes.
Skinner (1970) says that the term was first used in English in a letter by Thomas Beddoes (1760-1808) in a letter to Robert W. Darwin (1766-1848) in 1793. Robert Darwin was an English physician, father or Charles Darwin (1809-1882) author of “The Origin of the Species”.
