Safety, Cautions & Contraindications

Safety note[12, 13, 14, 15]Caution

Duke (2002) describes cleavers as a diuretic, lymph tonic, and depurative with experimental support (score 1). The plant has been used in traditional medicine for swollen lymph nodes, urinary complaints, and skin conditions. Diuretic and anti-inflammatory activities are supported experimentally. No Commission E approval. Safety rating is ++ (relatively safe), with no known significant contraindications at usual herbal doses (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

Scrambling, sprawling annual herb covered in tiny hooked bristles on its square stems, leaves and seed capsules, allowing it to cling to clothing, fur and neighbouring plants as it climbs ('stickyweed'). The leaves are narrow and lance-shaped, borne in whorls of six to eight. Tiny white, four-petalled flowers give way to small, round, bristly-hooked twin seed capsules ('goosegrass burrs').[6]

Height: Scrambling stems to 1-2 m, supported by other vegetation
Habit: Scrambling, sprawling annual herb, climbing by hooked bristles
Leaves: Narrow, lance-shaped, in whorls of 6-8, with hooked bristles on the margins
Flowers: Tiny, white, four-petalled
Stem: Square-sectioned, weak, covered in tiny hooked bristles
Root: Shallow, fibrous root system
Fruit: Small, round, bristly-hooked twin nutlet, clinging to fur and clothing
Flowering Period: May-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

A common scrambling weed of hedgerows, waste ground, gardens and field margins, climbing over other vegetation for support; native to Europe, Asia and North Africa and widely naturalised elsewhere.[6]

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 whole aerial plant (leaf, stem and seed) is cut in spring to early summer, before the fruit fully hardens, and used fresh (as juice) or dried.

Parts: Leaf, Seed, Stem
Season: Spring to early summer

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

Cleavers has a long European folk history as a lymphatic and diuretic 'spring tonic' herb, traditionally used to support the urinary system and lymphatic drainage, and topically as a soothing, emollient wash or poultice for skin irritation, wounds and minor swellings.[6]

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

Fresh juice[6]

Fresh aerial parts crushed or juiced, traditionally taken as a spring tonic or applied topically to skin irritation and wounds.

Poultice/wash[6]

Crushed fresh herb or a strained infusion applied topically as a wash or poultice for skin irritation and minor wounds.

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.
