    Study Notes

    Toxicological Examination

    • The stage of Toxicological Examination that involves Ultraviolet spectrophotometric methods, spectrofluorometry, and HPLC is the analytical stage.
    • The primary purpose of general extraction methods in toxicological examination is to isolate and separate the components of a substance.

    Treatment of Poisoning

    • The most appropriate treatment for Datura poisoning is supportive care and management of symptoms, as there is no specific antidote.

    Damiana Herb

    • The primary medicinal use of Damiana herb is as an aphrodisiac and to treat anxiety, depression, and insomnia.
    • The compound in Damiana herb that can cause tetanus-like convulsions and change the mental status when ingested in high doses is Thymol.

    Forensic Botany

    • The main focus of forensic botany is the application of botanical science to aid in the investigation and prosecution of crimes.
    • The compound isolated from plants that has been used in criminal acts is Aconitine.
    • Aconite root was historically used for criminal purposes as a poison to commit murder.
    • Plant evidence, such as leaves, seeds, or pollen, can be used in forensic botany to help realize important facts.
    • Forensic botany became an actual way of solving cases in the 1980s.

    Toxicological Examination (continued)

    • The stage of the Toxicological Examination that involves the identification of drugs in isolated extracts using Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) is the confirmatory stage.
    • The characteristic manifestations of anticholinergic poisoning caused by Datura intoxication include dry mouth, dilated pupils, and increased heart rate.
