  • A Medical-Historical Examination of the Death of Alexander the Great
    A MEDICAL-HISTORICAL EXAMINATION OF THE DEATH OF ALEXANDER THE GREAT Abstract: Alexander the Great’s cause of death has been contentious since antiquity. Historians and physicians alike have proposed a multitude of hypotheses. However, neither party is without their analytical flaws. The historians often neglect obvious medical refutations. Meanwhile, the physicians often err by forsaking disciplined historical methodology. Therefore, the authors of this paper subject these prior hypotheses to both Nathan Gamble medical and historical criticism, in order to provide a multidisciplinary University of Toronto, Toronto, Canada approach to a longstanding mystery. Some hypotheses have more weight St. Mary’s University, Twickenham, London than others, as is discussed. The most probable of the poisoning hypotheses, [email protected] which aligns with the Vulgate tradition of Alexander’s death, cites the use of Veratrum album, a plant derived bane. When the Court tradition is considered, Edmund F. Bloedow i.e. that no foul play occurred, acute pancreatitis induced by alcohol abuse holds greatest credence as a hypothesis. It is hoped that the approach used Augustine College, Ottawa, Ontario will not only increase clarity regarding Alexander’s death and challenge weak [email protected] ideas but also provide an approach by which speculation about other medical diagnoses in history may be tempered and critiqued. Keywords: Alexander the Great, Retrospective Diagnosis, Regicide, Murder, Death DOI: 10.14795/j.v4i3.269 ISSN 2360 – 266X ISSN–L 2360 – 266X ACKNOWLEDGMENTS: The authors would like to thank Joel Gamble and Jonathan Madany for the kind help in reviewing and preparing the manuscript for publication.

Summary An assessment of safety considerations with respect to human usage of complementary medicine preparations made from the substance Aconite (any part of the plant Aconitum napella, otherwise known as Monkshood), has been undertaken. The available toxicological data was reviewed, and levels of intake of the known toxic constituents, the alkaloids aconitine, mesaconitine and jesaconitine, known to be associated with adverse effects and possible fatality in humans, were determined. From this assessment, concentration levels of the known toxic alkaloids below which no toxic effects would normally be associated with their internal ingestion or use, was determined. Levels of ingestion of these toxic components which could normally be deemed as completely safe, were then ascertained. This assessment was then applied to an evaluation of homoeopathic Aconite-containing preparations available in the marketplace, to select ‘cut off points’ below which general sales classification is deemed appropriate. These calculations were based upon both concentration levels of the toxic alkaloids, as well as the maximum recommended pack size of preparations containing them. Aconite: an introduction Aconite (a preparation made from either the roots or herb of the European shrub Aconitum napellus, or other Aconitum species ), has long been used both as a traditional herbal medicine as well as a homoeopathic remedy.

De materia medica Cover of an early printed version of De materia medica. Lyon, 1554AuthorPediaus Dioscorides Strange plants RomeSubjectMedicinal, DrugsPublication date50-70 (50-70)Pages5 volumesTextDe materia medica in Wikisource De materia medica (Latin name for Greek work Περὶ ὕλης ἰατρικῆς, Peri hul's iatrik's, both means about medical material) is a pharmacopeia of medicinal plants and medicines that can be obtained from them. The five-volume work was written between 50 and 70 CE by Pedanius Dioscorides, a Greek physician in the Roman army. It was widely read for more than 1,500 years until it supplanted the revised herbs during the Renaissance, making it one of the longest of all natural history books. The paper describes many drugs that are known to be effective, including aconite, aloe, coloxinth, colocum, genban, opium and squirt. In all, about 600 plants are covered, along with some animals and minerals, and about 1000 medicines of them. De materia medica was distributed as illustrated manuscripts, copied by hand, in Greek, Latin and Arabic throughout the media period. From the sixteenth century, the text of the Dioscopide was translated into Italian, German, Spanish and French, and in 1655 into English. It formed the basis of herbs in these languages by such people as Leonhart Fuchs, Valery Cordus, Lobelius, Rembert Dodoens, Carolus Klusius, John Gerard and William Turner. Gradually these herbs included more and more direct observations, complementing and eventually displacing the classic text.

Input from everybody interested in plants is welcome and appreciated. Hellebore There are fifteen species of Hellebores commonly known as Lenten Rose. Most of the genus has shiny evergreen leaves, forming attractive clumps 9-18 inches tall and 24 inches wide. Hellebores have the added attraction of being extremely deer-resistant. They are among the first perennials to bloom, starting in February in many locations and continuing until spring. The lovely flowers are in shades of purple, pink, and white. Hellebores www.avidgardeners.org require partial shade, good drainage, adequate moisture, and thrive best in nearly neutral soils.

  • Helleborus Niger Helleborus Niger, Commonly Called Christmas Rose Or Black Hellebore, Is an Evergreen Perennial Flowering Plant in the Buttercup Family, Ranunculaceae
    Helleborus niger Helleborus niger, commonly called Christmas rose or black hellebore, is an evergreen perennial flowering plant in the buttercup family, Ranunculaceae. It is poisonous. Although the flowers resemble wild roses (and despite its common name), Christmas rose does not belong to the rose family (Rosaceae). Taxonomy The black hellebore was described by Carl Linnaeus in volume one of his Species Plantarum in 1753.The Latin specific name niger (black) may refer to the colour of the roots. There are two subspecies: H. niger niger and H. niger macranthus, which has larger flowers (up to 3.75 in/9 cm across). In the wild, H. niger niger is generally found in mountainous areas in Switzerland, southern Germany, Austria, Slovenia, Croatia and northern Italy. Helleborus niger macranthus is found only in northern Italy and possibly adjoining parts of Slovenia. Description Helleborus niger is an evergreen plant with dark leathery pedate leaves carried on stems 9–12 in (23–30 cm) tall. The large flat flowers, borne on short stems from midwinter to early spring, are generally white, but occasionally purple or pink. The tips of the petals may be flushed pink or green, and there is a prominent central boss of yellow. Horticulture The plant is a traditional cottage garden favourite because it flowers in the depths of winter. Large- flowered cultivars are available, as are pink-flowered and double-floweredselections. It can be difficult to grow well; acid soil is unsuitable, as are poor, dry conditions and full sun. Moist, humus-rich, alkaline soil in dappled shade is preferable. Leaf-mould can be dug in to improve heavy clay or light sandy soils; lime can be added to 'sweeten' acid soils.

  • Toxic/Poisonous to Livestock Plants of Mongolian Rangelands
    Toxic/Poisonous to Livestock Plants of Mongolian Rangelands Daalkhaijav Damiran and Enkhjargal Darambazar Eastern Oregon Agricultural Research Center, Union, OR-97883, Oregon, USA Briefly about Mongolian rangelands Mongolian natural rangeland covers 128.8 million ha. There are about 2823 vascular plant species and over 662 genera and 128 families have been recorded (Gubanov, 1996). Mongolian rangeland can be divided into 4-5 zones according to locations that differ in landscape, annual and seasonal climatic conditions, species composition and growth rate: high mountains, forest-steppe, steppe, desert-steppe and desert belt. Desert-steppe and desert belt account for 44.6% of the pastureland and the main domestic herbivores are camels and goats. Forest-steppe and high mountains accounts for 27.4% and the main domestic herbivores are cattle, sheep, horse and yaks. The rest 28% of the pastureland belongs to steppe and is the main stock-raising zone for cattle, sheep, horse, camels and goats. Mongolia is the only country of Eurasia to retain huge areas of steppes vegetation (Gunin et al. 1999). Mongolian rangeland is distributed over the extremely continental climate with harsh continental and extremely unpredictable climatic conditions. North and central part of country’s isohyets of 250-300 mm annual rainfall and over the southern-desert part of the country 50 to 100 mm annual rainfall. In Mongolia, the growing season is short and very dependent on climate, particularly rainfall. New growth in the forest steppe and steppe zones begins in mid- April, whereas elsewhere it may not begin until mid-May. Growth is often very slow, and the grazing of young grass may only be possible after 30-35 days.
