Identification of Biblical Hyssop and Origin of the Traditional Use of Oregano-Group Herbs in the Mediterranean Region

Alexander Fleisher and Zhenia Fleisher published this peer-reviewed article in the journal Economic Botany in 1988, arguing from comparative ethnobotany of the oregano group herbs that the hyssop mentioned in the Bible is the carvacrol chemotype of what is now classified as Origanum syriacum. Its strength is a genuine, checkable botanical argument, the identification is reasoned from documented traditional usage patterns across the Mediterranean region rather than assumed from tradition alone, and its bibliographic details are independently confirmed against Crossref and NASA's astrophysics data system. Its limit is that the identification is reached by inference from later usage rather than from an ancient botanical description of the plant itself, which is exactly why the biblical hyssop's identity remains an open question rather than a settled one.
