Psychoactive Plants

When the ingestion of a plant has an notable affect on the human consciousness, we might call this a psychoactive plant. Drinking a cup of coffee for the stimulating effect of caffeine is a good example of everyday ingestion of psychoactive plants. Besides stimulating effects, we could distinguish between psychoactive plants that have a sedative effect (for exemple valerian) and/or psychedelic effects (think of Cannabis).

A definition by Rätsch: ‘Psychoactive plants are plants that people ingest in the form of simple or complex preparations in order to affect the mind or alter the state of consciousness.’ (The Ecyclopedia of Psychoactive Plants, 2005)
