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.
