Mephedrone (4-methylmethcathinone) is a designer drug of the phenethylamine family that is able to cause central nervous system stimulation, psychoactivity and hallucinations and that is becoming popular among youth as a recreational drug. Mephedrone has been available in Europe since 2007, and it is sold through the internet and by local shops as bath salt or plant food. Read More

    [Acute intoxication in adults - what you should know].
    Dtsch Med Wochenschr 2014 Jan 3;139(1-2):31-46; quiz 43-6. Epub 2014 Jan 3.
    München.
    Ingestion of household products and plants are the leading cause for calls to the poison control centres as far as children are involved. Severe intoxication in children has become infrequent due to childproofed package and blister packs for drugs. Chemical accidents in adults give rise to hospital admission in only 5 %. Read More

    Belladonna Alkaloid Intoxication: The 10-Year Experience of a Large Tertiary Care Pediatric Hospital.
    Am J Ther 2016 Jan-Feb;23(1):e74-7
    1Division of Pediatric Emergency Medicine, Department of Pediatrics, Dana-Dwek Children Hospital, Tel Aviv University, Tel Aviv, Israel; 2Division of Clinical Pharmacology and Toxicology, Ichilov Hospital, Tel Aviv University, Tel Aviv, Israel; and 3Division of Pediatric Emergency Medicine, Department of Pediatrics, and 4Division of Clinical Pharmacology and Toxicology, The Hospital for Sick Children, University of Toronto, Ontario, Canada.
    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

    Crit Care Clin 2012 Oct 30;28(4):517-26. Epub 2012 Aug 30.
    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. Cocaine is commonly abused by inhalation, nasal insufflation, and intravenous injection, resulting in many adverse effects that ensue from local anesthetic, vasoconstrictive, sympathomimetic, psychoactive, and prothrombotic mechanisms. Cocaine can affect all body systems and the clinical presentation may primarily result from organ toxicity. Read More

    Application of an enantioselective LC-ESI MS/MS procedure to determine R- and S-hyoscyamine following intravenous atropine administration in swine.
    Drug Test Anal 2012 Mar-Apr;4(3-4):194-8. Epub 2011 Oct 1.
    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

    Plant poisons: their occurrence, biochemistry and physiological properties.
    Sci Prog 2010 ;93(Pt 2):181-221
    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

    Tex Heart Inst J 2009 ;36(4):342-4
    Department of Cardiology, Ankara Turkiye Yuksek Ihtisas Hospital, Ankara, Turkey.
    An unusual type of food poisoning, mad-honey intoxication, can be observed in the Black Sea region of Turkey and various other parts of the world. It can occur after ingestion of grayanotoxin-contaminated honey produced from the nectar of Rhododendron ponticum and other plant species, chiefly of the Ericaceae and Sapindaceae families.

    Plasma level of atropine after accidental ingestion of Atropa belladonna.
    Clin Toxicol (Phila) 2009 Jul;47(6):602-4
    Central Institute of the Bundeswehr Medical Service, München, Germany. reinhardbogan@ bundeswehr.org
    Background: Ingestion of toxic plant constituents still poses a challenge in clinical management. The amount of berries ingested is often unclear and in the case of Atropa belladonna may affect clinical outcome. Plasma levels of atropine may thus be useful in confirming the cause of intoxication.

    Emergency Department, Northern General Hospital, Sheffield S5 7AU, UK.
    Although death owing to the toxic effects of the therapeutic Digitalis lanata extract, digoxin has been reported, there are no reported cases of fatal Digitalis purpurea (digitoxin) plant intoxication in humans in the literature. We describe a case of ingestion of Digitalis purpurea in a 64-year-old man, which was fatal despite administration of Digibind. A review of the literature and aspects of management of plant digitalis poisoning are discussed. Read More

    J Appl Toxicol 2007 Mar-Apr;27(2):116-21
    Physician Assistant Branch, Department of Medical Sciences, AMEDD Center and School, Ft. Sam Houston, Texas 78234, USA.
    Anisodamine is a naturally occurring atropine derivative that has been isolated, synthesized and characterized by scientists in the People's Republic of China. Like atropine and scopolamine, anisodamine is a non-specific cholinergic antagonist exhibiting the usual spectrum of pharmacological effects of this drug class. It appears to be less potent and less toxic than atropine and displays less CNS toxicity than scopolamine. Read More

    The early toxicology of physostigmine: a tale of beans, great men and egos.
    Toxicol Rev 2006 ;25(2):99-138
    National Poisons Information Service (Birmingham Centre), City Hospital, Birmingham, UK.
    Mid-19th century European visitors to Old Calabar, an eastern province of Nigeria, could not avoid becoming aware of native belief in the power of the seeds of a local plant to determine whether individuals were innocent or guilty of some serious misdemeanour. The seeds were those of a previously unknown legume and soon referred to as the ordeal bean of Old Calabar. Their administration was known locally as 'chop nut'. Read More

    Saudi Med J 2005 Jan;26(1):118-21
    Department of Pediatrics, Armed Forces Hospital Southern Region, PO Box 101, Khamis Mushayt, Kingdom of Saudi Arabia.
    Datura is a hallucinogenic plant found in urban or rural areas in the Kingdom of Saudi Arabia KSA. It grows wildly in many parts of the country. Its taste and shape makes it unattractive to both man and animals, though deliberate use by young adults for its hallucinogenic effects have been widely reported for the past 30 years. Read More

    Association of diamine oxidase and S-adenosylhomocysteine hydrolase in Nicotiana tabacum extracts.
    Plant Mol Biol 2004 Sep;56(2):299-308
    Plant Pathology, Physiology, and Weed Science Deptartment, Fralin Biotechnology Center, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061-0346, USA.
    The oxidative deamination of methylated putrescine by a diamine oxidase activity (DAO) is an important step in the biosynthesis of nicotine in tobacco and tropane alkaloids in several Solanaceous plants. A polyclonal rabbit antiserum was previously developed to a purported purified DAO enzyme from Nicotiana tabacum. The antiserum bound to a single 53 kDa protein and immunoprecipitated 80% of DAO activity from tobacco root extracts. Read More

    Six clinical cases of Mandragora autumnalis poisoning: diagnosis and treatment.
    Eur J Emerg Med 2002 Dec;9(4):342-7
    Department of Internal and Emergency Medicine, University of Catania, St Marta Hospital, via G. Clementi 36, 95124 Catania, Italy.
    A multiple case of Mandragora autumnalis poisoning is described. Mandragora autumnalis, a solanaceous plant that is common in the Sicilian countryside, contains a variable concentration of solanum alkaloids, which cause gastrointestinal irritation, and tropane alkaloids, which have anticholinergic properties and produce typical and sometimes severe atropine-like symptoms. Vital function support, decontamination, symptomatic treatment and, in severe cases, antidote therapy with physostigmine are useful to control acute poisoning. Read More
