    Study Notes

    Herbal Medicine Definition

    • Herbal medicine involves using plants or plant parts (like leaves, seeds, and bark) for medicinal purposes to treat or prevent health issues.

    History of Herbal Medicine

    • Ancient cultures that used herbal medicine include the Egyptians, Neanderthals, Ayurvedic medicine in South Asia, Chinese medicine in East Asia, and Western herbal medicine in Europe and America.

    Phytochemistry

    • Primary Metabolites: Essential for plant growth and function, examples are starch (energy storage), cellulose (structural support), and chlorophyll (photosynthesis).
    • Secondary Metabolites: Aid in a plant's defense and survival; in humans, they have therapeutic effects. Examples are:
      • Caffeine (stimulant)
      • Tannins (astringent)
      • Alkaloids (nervous system stimulants)

    Herbal Safety Considerations

    • Always ensure proper dosage.
    • Avoid using certain herbs during pregnancy unless advised by a healthcare professional.
    • Be aware of potential herb-drug interactions. For example, garlic interacts with anticoagulants.
    • Monitor for adverse effects, such as allergic reactions.

    Dosage Considerations

    • Adults: Follow product label instructions.
    • Children: Use reduced doses (half for 9-year-olds is a common guideline).
    • Seniors: Use lower doses due to reduced liver and kidney function, particularly after age 80.

    Herbal Preparations

    • Infusion: A herbal tea made by steeping delicate plant parts (like leaves and flowers) in hot water. Used to extract water-soluble phytochemicals. Example: Peppermint tea for digestive issues.
    • Decoction: Made by boiling tougher plant parts (like roots and bark) to extract water-soluble compounds. Used for herbs like dandelion root for liver support.

    Digestive System Herbs

    • Ginger: Antiemetic (reduces nausea).
    • Peppermint: Antispasmodic (relieves Irritable Bowel Syndrome (IBS) symptoms).
    • Slippery Elm: Demulcent (soothes mucous membranes).

    Liver Health Herbs

    • Milk Thistle: Hepatoprotective (protects liver cells from toxins).
    • Dandelion Root: Choleretic (increases bile production).

    Respiratory System Herbs

    • Thyme: Expectorant (helps clear mucus).
    • Cinnamon: Diaphoretic (promotes sweating for fevers).
    • Garlic: Antimicrobial and mucolytic (breaks down mucus).

    Immune System Herbs

    • Echinacea: Immune-enhancing (stimulates immune cells).
    • Astragalus: Immune-modulating (supports chronic immune issues).
    • Turmeric: Anti-inflammatory (reduces inflammation in the body).

    Adaptogens

    • Adaptogens help the body resist stress.
    • Examples:
      • Ashwagandha: For anxiety and stress
      • Korean Ginseng: For energy and stamina

    Nervous System Herbs

    • Lavender: Anxiolytic (reduces anxiety).
    • Passionflower: Sedative (promotes sleep).
    • Rosemary: Nootropic (improves memory).

    Reproductive System Herbs

    • Chaste Berry: Hormone modulator (supports Premenstrual Syndrome (PMS) and luteal insufficiency).
    • Dong Quai: Uterine tonic (supports menstruation and circulatory health).
