    Study Notes

    Toxic Plants

    • Plant toxins are secondary metabolites with both helpful and harmful effects in humans and animals, ranging from minor side effects to severe ones such as psychosis and paralysis.
    • Toxins enter the body through inhalation, ingestion, or contact.
    • Toxicity varies by plant location, climate, soil, fertilization, variety, and age.
    • Plant toxins are categorized according to the organ system they affect (e.g., cardiotoxins, neurotoxins).

    Hallucinogens

    • Many cultures have used hallucinogens, often with religious significance.
    • Hallucinogenic plants contain alkaloids similar to neurotransmitters (noradrenaline, 5-hydroxytryptamine).
    • Fungi: Some poisonous fungi (Amanita, Psilocybe, Conocybe) produce hallucinations.
    • Amanitas: Include toxic species with hallucinogenic effects.

    Fly Agaric

    • Fly agaric (Amanita muscaria) is recognizable by its red cap with white flecks.
    • Contains isoxazole alkaloids, ibotenic acid, and muscimol.
    • Some components possess antitumor activity.

    Hallucinogenic Mexican Mushrooms

    • Species of Psilocybe, Conocybe, and Stropharia cause hallucinations.

    Puffballs

    • Lycoperda species produce auditory hallucinations and a state of half-sleep after consumption.

    Lysergic Acid Derivatives

    • Lysergic acid and its diethylamide (LSD) derivatives are well-known hallucinogens.
    • Can be produced from suitable cultivation of the fungus.

    Morning Glory Seeds

    • Some species of Ipomoea produce hallucinogenic effects.
    • Closely related to Argyreia species in their constituents and action.

    Peyote

    • Cactus like Lophophora williamsii are used for their hallucinogenic alkaloid content (mescaline).

    Indian Hemp

    • Was originally considered a separate species but classified as a variety of Cannabis sativa.
    • Varieties exhibit different cannabinoid mixtures.
    • Grown for fiber and seeds (30-35% drying oil).
    • Produces products like ganja and hashish.

    Medicinal Uses of Cannabis

    • Used in treating hysteria, movement disorders, and some cancers.
    • Used as an aphrodisiac.
    • Active ingredient is tetrahydrocannabinol (THC).

    Other Higher Plants

    • Nutmeg contains elements like miristicin and elemicin that may produce psychotropic effects.
    • Virola species (Myristicaceae) are used as hallucinogenic snuff.

    Natural Allergens

    • Various plant and animal parts can trigger allergic reactions in susceptible individuals.
    • Allergenic materials are transmitted through contact, airborne pollens, and animal fur.
    • Common allergens include:
      • Pollen (seasonal hay fever)
      • Spores of molds (rhinitis, asthma)
      • Rhus species (contact dermatitis)
      • Sesquiterpene lactones (allergic contact dermatitis)
      • Plants like Rue and Dumb Cane

    Teratogens of Higher Plants

    • Ingested substances (from plants) can cause fetal abnormalities.
    • Teratogens affect the developing fetus during a specific gestational period.
    • Different plant constituents (alkaloids, coumarins, lignans, macrolides) can be teratogenic.

    Other Toxic Plants

    • Pharmacists should be familiar with poisonous plants locally.
    • Poisoning occurs through ingestion of berries, seeds, or other parts.
    • Toxicity can vary depending on the species, plant, and individual.
    • Poisonous plants include umbelliferae members.
    • Hepatotoxic pyrrolizidine alkaloids are found in some plants.

    Other Toxic Compounds

    • Some fungi produce mycotoxins like aflatoxins (Aspergillus species), which can be harmful.
    • Safrole and other alkenylbenzene derivatives have been linked to increased liver cancer risk in animal studies.
