Ledol is a poisonous sesquiterpene that can cause cramps, paralysis, and delirium. Caucasian peasants used Rhododendron plants for these effects in shamanistic rituals. Ledol resides in the essential oils of certain plants and when crushed, these oils are released. One of the plants with the highest concentration of these essential oils is Rhododendron tomentosum.

The word "ledol" comes from the Greek word "ledos" meaning "robe". This likely comes from the "wooly" appearance of the plant, which has hair-like stalks stemming from the flower.
