Written by respected professors of botany and pharmaceutical biology, this is the definitive account of plants and mushrooms used for poison darts, traditional medicine, ceremonial and spiritual purposes, and recreational drugs. Hazardous plants are commonly used as garden ornamentals, potted plants, or florist flowers, yet many people are unaware of the dangers posed by the toxins derived from them. In addition to exploring plants that are ingested, the authors also treat plants that cause irritation and inflammation of the skin and mucous membranes. A special focus is given to psychoactive plants, which can have stimulant, sedative, hypnotic, narcotic, or hallucinogenic properties. These include coca, opium, cannabis, and scopolamine. Mind-Altering and Poisonous Plants of the World is a must for gardeners, farmers, veterinarians, botanists, pharmacists, chemists, doctors, and poison control centers.
