ABSTRACT
Plant species have different uses in different countries as well as different areas of the same country (Farnsworth and Soejarto 1991; Plotkin 2000; Hamilton 2004; Halberstein 2005). The relationship between humans and plants has existed since the existence of human beings, and the earliest documented record dates from the Paleolithic age (50,000 BC); plants were found in the grave of a Neanderthal man in the southern part of Hakkari (far southeast edge of Turkey) (Baytop 1984, 1999).
