Key Constituents

Iridoid glycosides (harpagoside, harpagide, procumbide)[12, 13, 14]

Harpagoside is the main marker compound and anti-inflammatory principle; effective extracts are standardised to it, with the better-quality clinical evidence using preparations delivering roughly 50-60 mg harpagoside per day.

Phenylethanoids (acteoside/verbascoside) and flavonoids[13]

Antioxidant supporting constituents.

Verbascoside (acteoside)Flavonoids
Mucilage polysaccharides[11]

The high mucilage content gives the demulcent, soothing action.

Safety, Cautions & Contraindications

Safety note[13]Caution

Because it is a bitter that increases stomach-acid and bile secretion, it is contraindicated in active peptic ulcer, gastritis and (without medical supervision) gallstones.

Safety note[13]Caution

May add to the effect of anticoagulants (e.g. warfarin) and may influence blood sugar, blood pressure and heart rhythm; use caution with these medicines.

Safety note[13]Caution

Avoid during pregnancy (oxytocic/uterine effect) and while breastfeeding.

Safety note[11]Info

Generally very well tolerated. Irritation of the mouth/throat or a cough that persists beyond about a week, or is accompanied by fever or breathlessness, needs medical assessment.

Safety note[11]Caution

Use in pregnancy and breastfeeding is not recommended in the absence of adequate data.

Botanical Description

Low-growing, sprawling perennial herb with trailing stems and deeply lobed, greyish-green leaves arising from a large, fleshy primary taproot bearing smaller secondary storage tubers (the part used medicinally). Striking funnel-shaped, purplish-pink to violet flowers give way to a distinctive woody fruit covered in long, hooked spines - the origin of the common name.[13]

Height: Trailing stems to 1.5 m, low-growing
Habit: Low-growing, sprawling perennial herb
Leaves: Deeply lobed, greyish-green
Flowers: Funnel-shaped, purplish-pink to violet
Stem: Trailing, sprawling stems
Root: Large primary taproot with smaller secondary storage tubers (the medicinal part)
Fruit: Woody capsule covered in long, hooked spines ('devil's claw')
Flowering Period: Summer (during the rainy season)

Biennial or short-lived perennial herb, 30-120 cm tall, with erect or sprawling, branched, often reddish stems. Leaves are alternate, long-stalked and palmately lobed with 5-7 shallow rounded lobes and toothed margins. Flowers are pink-purple with darker veining, with five notch-tipped petals borne in small axillary clusters. The fruit is a flattened, disc-shaped schizocarp ('cheese') that splits into a ring of small single-seeded nutlets.[2]

Height: 30-120 cm
Habit: Erect to sprawling biennial/perennial herb
Leaves: Alternate, long-stalked, palmately 5-7-lobed with toothed margins
Flowers: Pink-purple with darker veins, five notched petals, in small axillary clusters
Stem: Erect or sprawling, branched, often reddish
Root: Taproot
Fruit: Flattened disc-shaped schizocarp ('cheese') of small nutlets
Flowering Period: June-September

Habitat

Native to the dry savannas and semi-desert regions of southern Africa, particularly the Kalahari Desert region of Namibia, Botswana and South Africa.[13]

Common on roadsides, waste ground, hedgebanks and field margins across Europe, North Africa and temperate Asia, and widely naturalised elsewhere; tolerates a wide range of soils, favouring sunny, disturbed, nitrogen-rich sites.[2]

Harvesting

The secondary root tubers are dug by hand, sliced and dried in the sun, traditionally by local harvesters in southern Africa; sustainable wild-harvesting practices are important given the plant's slow growth and habitat sensitivity.

Parts: Secondary root tuber

Leaves and flowers are gathered during the flowering period (summer) and dried quickly out of direct sun to preserve their mucilage content; fresh material can also be used directly for infusions or poultices.[11]

Parts: Leaf, Flower
Season: Summer, during flowering

Traditional Uses

Devil's claw has a long southern African traditional-medicine history as a remedy for fever, pain and digestive complaints, and is now one of the most clinically studied herbal analgesics for osteoarthritis and chronic low back pain, with standardised extracts showing efficacy comparable to some conventional analgesics in trials.[13]

Mallow leaf and flower have a long ethnobotanical history across Europe as a demulcent for irritated mucous membranes - soothing coughs, sore throat and mouth irritation - and for occasional constipation and skin irritation, reflecting the mucilage-rich leaf and flower. Modern phytochemical and pharmacological work confirms antioxidant, anti-inflammatory, antimicrobial and wound-healing activity of its extracts.[2, 11]

Preparations

Standardised extract[13, 14]

Root tuber extract standardised to harpagoside content, taken as capsules or tablets; the best-studied clinical form for osteoarthritis and back pain.

Infusion (hot)[11]

Dried leaf and/or flower steeped in hot water as a traditional soothing tea for cough, sore throat and mild digestive irritation.

Poultice/compress[7]

Crushed fresh or softened dried leaf applied externally to soothe irritated or inflamed skin.

Dosage

Standardised extract[14]

Clinical trials for osteoarthritis and back pain commonly use extracts providing around 50-60 mg harpagoside daily. Educational reference only, not a prescription.

Infusion[11]

EMA herbal-monograph guidance suggests roughly 1.5-2 g of dried leaf or flower per cup, taken as an infusion up to 3 times daily. Educational reference only, not a prescription.
