Related to sage and tarragon, it is the primary ingredient in the alcoholic beverage called Absinthe, known for the little green fairy.

When reading the book of Revelations, or any related type book, it usually works best to first see it as a metaphor, then from the time it was written. Wormwood is mentioned seven times in the Hebrew Testament and once in the Christian Testament, always with the implication of bitterness. Because of the chemical in the herb that promotes psychedelic experiences, one might see the image as people being lead by an illusion, fantasy, or holding to that pursuit with no real intent on the goals.
