Since ancient times, poisonous plants and mushrooms have been used for hunting, murder and magic. Most cultures of the world have learnt to avoid these plants or to use them with discretion. Many of the plants are still widely used as traditional medicine for their therapeutic value in the treatment of diseases.

Hazardous plants are commonly used as garden ornamentals, pot plants or florist flowers, and many people are no longer aware of the inherent dangers posed by toxic plants or medicines derived from them. Also included in this illustrated guide are plants causing irritation and inflammation of the skin and mucous membranes. A special focus is on psychoactive plants which can have stimulant, sedative, hypnotic, narcotic or hallucinogenic properties, such as coca, opium, cannabis and scopolamine.

Descriptions and illustrations for all 77 genera and 368 known species are provided, as well as a key to the genera. Introductory chapters focus on habit (growth form) and roots, leaves, synflorescences, flowers, fruits, chromosome numbers, pollinators, chemistry, plant uses, and phylogenetic relationships of African Apiaceae.
