Psychotropic refers to the herb or plant’s ability to affect thoughts, behaviours, mood, or perception. Psychotropic, also known commonly as psychedelic herbs typically, are often associated with negative connotations. Their capacity to be used as medicine has been explored extensively for thousands of years in traditional medicine, and in the last century by the global scientific community. Occasionally, the psychotropic qualities of a plant or herb can depend on the amount ingested, and quite a few known psychotropic species are common or even ornamental plants.
