Common anticholinergic solanaceaous plants of temperate Europe - A review of intoxications from the literature (1966-2018).

Toxicon 2020 Apr 13;177:52-88. Epub 2020 Feb 13.

Faculty of Pharmacy, University of Ljubljana, Tržaška Cesta 32, 1000, Ljubljana, Slovenia.

Datura stramonium, Atropa belladonna, Hyoscyamus niger, and Scopolia carniolica are all temperate plants from the family Solanaceae, which as a result of their anticholinergic tropane alkaloids, hyoscyamine/atropine and scopolamine, have caused many cases of poisoning around the world. Despite the danger these nightshade plants represent, the literature often presents incomplete cases lacking in details and filled with ambiguity, and reviews on the topic tend to be limited in scope. Many also point to a gap in knowledge of these plants among physicians. Read More

The belladonna alkaloids can be isolated from a number of plants, which contain hallucinogens that represent a serious danger to infants, children, and adolescents. Roots, leaves, and fruits of the plant contain the alkaloids atropine, hyoscyamine, and scopolamine, which can lead to an anticholinergic toxidrome; however, not all characteristics of the toxidrome are necessarily present in each case of poisoning. A retrospective chart review of all children seen following anticholinergic ingestions, between April 2001 and November 2010, at the Hospital for Sick Children in Toronto. Read More

Department of Medicine, Weill Cornell Medical College, New York, NY, USA.

Cocaine, a natural alkaloid derived from the coca plant, is one of the most commonly abused illicit drugs.

Bundeswehr Institute of Pharmacology andToxicology Neuherbergstrasse 11, Munich, Germany.

S-hyoscyamine (S-hyo) is a natural plant tropane alkaloid acting as a muscarinic receptor (MR) antagonist. Its racemic mixture (atropine) is clinically used in pre-anaesthesia, ophthalmology and for the antidotal treatment of organophosphorus (OP) poisoning with nerve agents or pesticides even though R-hyo exhibits no effects on MR. Further investigative research is required to optimize treatment of OP poisoning. Read More

Butterfly Conservation Warwickshire, Kenilworth, Warwickshire, UK.

Plants produce poisons as a defence against predators. Many of these substances are biosynthesised from non-protein amino acids by biosynthetic pathways which have been deduced from the results of isotopic tracer analysis. These secondary metabolites have been used by humans over thousands of years, both as drugs and as agents to kill animals and commit homicide. Read More
