Herbal products


Overview

  • Herbal products are preparations derived from plants or plant parts, used for therapeutic, preventive, or health-promoting purposes

  • They may contain whole plants, roots, leaves, seeds, flowers, or extracts, and can be formulated as teas, capsules, tablets, tinctures, essential oils, or topical applications

  • Often categorized as dietary supplements in many countries, meaning they may not undergo the same rigorous approval processes as prescription drugs

  • Utilized in traditional medicine systems such as Ayurveda, Traditional Chinese Medicine (TCM), Unani, and Western herbalism

  • Active constituents can be alkaloids, glycosides, terpenoids, flavonoids, tannins, saponins, and phenolic compounds


Classification by Therapeutic Use

  • Anti-inflammatory herbs – reduce inflammation (e.g., turmeric, boswellia, willow bark)

  • Digestive aids – support digestion, reduce bloating (e.g., peppermint, ginger, chamomile)

  • Cardiovascular support – improve circulation, regulate blood pressure (e.g., hawthorn, garlic, ginkgo biloba)

  • Immune modulators – enhance or regulate immune function (e.g., echinacea, astragalus, elderberry)

  • Nervine and mood support herbs – calm the nervous system or support mood (e.g., valerian, passionflower, St. John’s wort)

  • Liver-supporting herbs – hepatoprotective activity (e.g., milk thistle, dandelion root)

  • Urinary tract support – diuretic or anti-infective activity (e.g., cranberry, horsetail)

Safety Considerations

  • Quality control: Variable potency and purity, risk of contamination with heavy metals, pesticides, or adulterants

  • Drug-herb interactions: Some herbs affect CYP450 enzymes or clotting (e.g., St. John’s wort reduces levels of many drugs; ginkgo increases bleeding risk)

  • Toxicity: Some herbs are toxic in high doses (e.g., comfrey contains hepatotoxic pyrrolizidine alkaloids; aristolochia is nephrotoxic)

  • Pregnancy and lactation: Many herbs lack safety data or may cause uterine contractions or harm to the fetus

  • Allergic reactions: Possible, especially in individuals allergic to related plant families


Regulation

  • In the US: Regulated as dietary supplements under the Dietary Supplement Health and Education Act (DSHEA) – manufacturers are responsible for safety, labeling, and claims, but FDA approval is not required before marketing

  • In EU: Regulated under Traditional Herbal Medicinal Products Directive (THMPD) – products must meet quality and safety requirements and have evidence of traditional use
