A '''Western clinical herb''' is a plant medicine used within the Western herbal-medicine tradition as that tradition has been formalised in the modern era, principally through the British clinical-herbalist lineage (the National Institute of Medical Herbalists from 1864 onward, the British Herbal Pharmacopoeia from 1971, the regulatory framework of the European Medicines Agency's Committee on Herbal Medicinal Products from 2004) and through the American Eclectic medical tradition (the Eclectic medical schools and their pharmacopoeial works from the 1830s through the 1930s, principally documented in the ''King's American Dispensatory'' of 1898). The Western clinical lineage is distinct from the older European folk-herbal tradition of Culpeper, Gerard, and the earlier herbalists, although it incorporates substantial material from those sources; it is distinct also from the European phytotherapy tradition of Germany and France, whose Commission E monographs and pharmaceutical-grade preparations have a parallel regulatory framework.

The clinical vocabulary of the tradition was largely established by the British herbalist [[wikipedia:Thomas Bartram|Thomas Bartram]] in his 1995 ''Encyclopedia of Herbal Medicine'' and by his successors. The vocabulary of pharmacologic action (alterative, anodyne, antispasmodic, carminative, demulcent, diaphoretic, emmenagogue, expectorant, nervine, vulnerary, and many others) survives essentially intact from its Eclectic-era formulation, and provides the action-class taxonomy of the modern tradition. The British Herbal Pharmacopoeia (BHP) prescribing format is the classical "tincture base + supportive infusion + topical adjunct + lifestyle counsel," with the dose conventions ('''1:5 tincture in 45% alcohol, 2-5 mL three times daily''' as the standard adult clinical strength) inherited from the early-twentieth-century pharmacopoeial work.

The American Eclectic tradition, founded by [[wikipedia:Wooster Beach|Wooster Beach]] in the 1830s and developed at the Eclectic medical schools (the Eclectic Medical Institute of Cincinnati, the most influential) until those schools were eliminated by the [[wikipedia:Flexner Report|Flexner Report]] of 1910, contributed several characteristic American herbs to the Western clinical pharmacopoeia: '''[[wikipedia:Hydrastis canadensis|goldenseal]]''' (''Hydrastis canadensis'', the antiseptic bitter), '''[[wikipedia:Echinacea|echinacea]]''' (''Echinacea purpurea'' and ''E. angustifolia''), '''[[wikipedia:Lobelia inflata|lobelia]]''' (the respiratory antispasmodic), '''[[wikipedia:Phytolacca|poke root]]''' (''Phytolacca americana''), '''[[wikipedia:Ulmus rubra|slippery elm]]''' (''Ulmus rubra''), '''[[wikipedia:Aletris farinosa|true unicorn]]''' (''Aletris farinosa''), '''[[wikipedia:Chamaelirium luteum|false unicorn]]''' (''Chamaelirium luteum''), '''[[wikipedia:Stone root|stone root]]''' (''Collinsonia canadensis''), and the various indigenous-American medicines that the Eclectics integrated from Native American sources. The Lloyd brothers' [[wikipedia:Lloyd Library|Lloyd Library]] in Cincinnati preserves the Eclectic pharmacopoeial literature and remains a working botanical-medicine reference today.

The modern Western herbal-medicine tradition has been substantially shaped by three contemporary developments. The first is the establishment of the European regulatory framework through the EMA's Committee on Herbal Medicinal Products in 2004, which created the simplified Traditional Herbal Medicinal Product (THMP) registration pathway under the EU Traditional Herbal Medicinal Products Directive 2004/24/EC. The second is the parallel development of the U.S. herbal-supplement market under the [[wikipedia:Dietary Supplement Health and Education Act of 1994|Dietary Supplement Health and Education Act of 1994]] (DSHEA), which made most herbal preparations available without prescription review but also without the efficacy review of a pharmaceutical. The third is the [[wikipedia:American Botanical Council|American Botanical Council]] and its publication ''HerbalGram'', which serve as the principal contemporary clearing house for clinical-trial evidence on Western herbal medicines.

== Herbs indexed ==

The Western clinical herbs of established use, as documented in the British Herbal Pharmacopoeia, the EMA HMPC monographs, the ESCOP monographs, and the Eclectic dispensatories, are progressively indexed as their individual monographs are built. The foundational set is large; selected core members: '''nervine''' (valerian, lemon balm, passionflower, hops, skullcap, oats, chamomile, vervain); '''cardiovascular''' (hawthorn, motherwort, garlic, lily of the valley, ginkgo); '''bitter / digestive''' (gentian, wormwood, dandelion, artichoke, milk thistle, fennel, peppermint, ginger); '''demulcent''' (slippery elm, marshmallow, comfrey, licorice, plantain); '''expectorant''' (mullein, thyme, elecampane, white horehound, hyssop, garlic, ivy leaf); '''vulnerary''' (calendula, comfrey, plantain, yarrow, witch hazel, St John's wort); '''women's''' (black cohosh, chasteberry, dong quai, blue cohosh, red raspberry leaf, motherwort, shepherd's purse); '''alterative''' (cleavers, burdock, red clover, yellow dock, dandelion root, sarsaparilla); and the Eclectic-specific medicines listed above.

== Notes on scope ==

The boundary of this category is "plant medicine of established use in the Western clinical herbal tradition (British Herbal Pharmacopoeia, EMA HMPC, ESCOP monographs, American Eclectic dispensatories), with a dedicated wiki monograph." The European phytotherapy tradition (Germany, France, Switzerland) is distinct in its emphasis on standardised pharmaceutical-grade preparations and on Commission E approval, but overlaps substantially in the medicines themselves; herbs of joint use are cross-indexed across both traditions where the regulatory framework provides distinct documentation. The Western popular-folk-herbal tradition (Mrs Grieve, Maud Grieve's ''A Modern Herbal'' of 1931 and similar) is partially incorporated through its overlap with the clinical tradition; the popular tradition is referenced on the individual herb pages where it adds to the clinical understanding.
