In this report we describe the unique capabilities of the α/β discrimination of the Borexino experiment. This capability is the direct result of years of development aimed at the design of an experiment that could withstand contamination from α-emitting nuclides. The combination of the excellent α/β discrimination and of the excellent radiopurity of the detector permitted to extract information on the solar neutrino interactions in Borexino without interference from α particles.
