 The reflex is named after Albert von Bezold and Adolf Jarisch Junior.The significance of the discovery is that it was the first recognition of a chemical (non-mechanical) reflex.von Bezold and Hirt described a reaction comprising a triad of bradycardia, hypotension, and apnea (hypopnea) resulting from an intravenous injection of an alkaloidal extract of "Veratrum viride" or "Viscum album" in 1867.
