Safety, Cautions & Contraindications

Safety note[13, 14]Caution

CAUTION: Contains thujone, which is neurotoxic in significant amounts. Internal use should be limited in duration and dose — short-term use only (under 4 weeks). Contraindicated in pregnancy (powerful uterine stimulant). Avoid in epilepsy, renal disease, and in children. The small amounts present in properly prepared bitter tinctures and vermouth are generally considered safe. The thujone content of absinthe was historically exaggerated.

Safety note[13, 14, 17]Caution

Duke (2002) rates wormwood as + (use with caution) and provides clinical evidence (score 2) for use as an aperitif and bitter digestive tonic, consistent with Commission E approval for dyspeptic complaints and loss of appetite. The plant contains absinthin and artabsin (bitter sesquiterpene lactones) responsible for digestive stimulation, and also thujone — a neurotoxic ketone that is the active agent responsible for 'absinthism' (historical neurological syndrome linked to absinthe consumption). Duke strongly cautions that thujone content limits safe long-term use, and wormwood should not be taken internally for more than 4 weeks at a time. Strictly contraindicated in pregnancy (abortifacient, neurotoxic) and epilepsy (Duke, 2002).

Safety note[12]Caution

Avoid internal use in pregnancy and breastfeeding: like goldenseal, the berberine it contains can cross the placenta and into milk and worsen newborn jaundice (kernicterus risk).

Safety note[11, 12]Caution

Berberine impairs the metabolism of some medicines - for example it raises blood levels of cyclosporine, risking toxicity - so use caution with prescription drugs. It is used mainly topically for skin conditions.

Botanical Description

Aromatic, silvery-grey perennial herb with finely divided, silky-hairy leaves and numerous small, pale yellow, drooping, globe-shaped flower heads borne in loose branched panicles. The whole plant has a characteristic intensely bitter taste and a pungent, sage-like aroma.[4]

Height: 60-120 cm
Habit: Erect, silvery-grey, aromatic perennial herb
Leaves: Finely divided (2-3-pinnatisect), silky-hairy, silvery-grey
Flowers: Small, pale yellow, drooping, globe-shaped flower heads in loose branched panicles
Stem: Erect, ridged, silvery-hairy, woody at the base
Root: Woody rootstock
Fruit: Small achene without pappus
Flowering Period: July-September

Evergreen shrub, 0.5-2 m tall, spreading by underground rhizomes to form thickets. The pinnate leaves resemble holly, with 5-9 glossy, dark green, spiny-toothed leaflets that often turn bronze-red in winter. Small, bright yellow, six-petalled flowers are borne in dense, upright terminal racemes in early spring, followed by clusters of blue-black, grape-like berries with a waxy bloom. The wood and inner bark of the stem and root are bright yellow when cut, owing to their high content of berberine-type alkaloids.

Height: 0.5-2 m
Habit: Evergreen, rhizomatous, colony-forming shrub
Leaves: Pinnate, holly-like, 5-9 glossy dark green spiny-toothed leaflets
Flowers: Small, bright yellow, six-petalled, in dense upright terminal racemes
Stem: Woody; wood and inner bark bright yellow when cut
Root: Woody, rhizomatous, bright yellow within (berberine-type alkaloids)
Fruit: Clusters of blue-black, grape-like berries with a waxy bloom
Flowering Period: Early spring (March-April)

Habitat

Grows on dry, sunny, stony or waste ground, roadsides and field margins; native to Europe, North Africa and temperate Asia, and naturalised in North America.[4]

Native to the Pacific Northwest of North America, growing in coniferous woodland understorey, forest margins and rocky slopes; widely introduced and naturalised as an ornamental and hedging shrub in temperate regions elsewhere.

Harvesting

The flowering aerial parts (leaf, stem and flower) are cut as flowering begins, in mid- to late summer, and dried in a warm, shaded, airy place.[4]

Parts: Flower, Leaf, Stem
Season: Mid- to late summer, at the start of flowering

The root and root bark, the medicinal parts, are dug from established plants - traditionally in autumn - and dried. Because wild populations are slow-growing, cultivated or nursery-sourced material is preferred over wild-harvesting.

Parts: Root, Bark
Season: Autumn

Traditional Uses

Wormwood is one of the classic bitter digestive herbs of European tradition, used to stimulate appetite and bile flow for dyspeptic complaints, and historically as a vermifuge (its common name reflects traditional use against intestinal worms) and in the production of absinthe and vermouth.[1, 4]

Oregon grape root has a traditional Native American and Eclectic-medicine history as a bitter tonic and alterative (blood-purifying) remedy and for skin conditions. Its main modern use, supported by clinical trials, is topical application of a standardised bark extract for mild-to-moderate psoriasis and atopic dermatitis (eczema), where its berberine-type alkaloids give anti-inflammatory and antiproliferative effects on skin cells.[1, 11, 12]

Preparations

Infusion[1]

Dried flowering herb infused briefly in hot water as a very bitter digestive tea, taken before meals to stimulate appetite.

Topical cream/ointment[1, 11, 13]

A standardised 10% Mahonia aquifolium bark extract cream, the best-studied form, applied to affected skin up to three times daily for psoriasis or eczema.

Dosage

Short-term use only[13]

Because of its thujone content, traditional herbal references limit internal use to small bitter doses (around 0.5-1 g dried herb per cup) for no more than about 4 weeks at a time. Educational reference only, not a prescription.

Topical 10% extract cream[11, 13]

Clinical trials in psoriasis and eczema have used a 10% Mahonia aquifolium bark extract cream applied to affected areas up to three times daily. Educational reference only, not a prescription; internal use is not well studied and should be supervised.
