Key Constituents
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.
Antioxidant supporting constituents.
Eugenol typically makes up the great majority of clove oil and is responsible for most of its analgesic, antimicrobial and anti-inflammatory activity.
Pharmacological Actions
Traditional & Indicated Uses
Anti-inflammatory and analgesic for osteoarthritis (hip and knee) pain; General joint pain and arthritis support
Effective at standardised doses (~50-60 mg harpagoside/day); an aqueous extract was non-inferior to rofecoxib for short-term chronic low back pain; Relief of chronic non-specific low back pain
inferred from anti-inflammatory action

Safety, Cautions & Contraindications
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.
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.
Avoid during pregnancy (oxytocic/uterine effect) and while breastfeeding.
Strong and concentrated: Clove oil is very potent and should always be diluted before skin or mouth use.Dental use: Undiluted clove oil can burn gums or skin.Blood thinning: Clove may increase bleeding risk in large amounts or with anticoagulants.Pregnancy: Culinary amounts are fine; medicinal doses should be used cautiously.Children: Essential oil should be used with extra caution and diluted well.
Duke (2002) rates cloves as +++ with clinical evidence (score 2) for analgesic activity — specifically, topical application of clove oil (eugenol) for dental pain is clinically validated. The plant also shows strong antimicrobial, antifungal (anti-Candida), antispasmodic, and antiviral activities at the experimental level. Commission E approves topical clove preparations for dental pain. Recommended dose: 1–5% clove oil preparation (topical) or 150 mg clove powder internally. The essential oil is irritating to mucous membranes and should not be applied undiluted to skin or mucous membranes (Duke, 2002).

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]
Evergreen tree (Myrtaceae), 8-12 m tall (occasionally to 20 m), with a pyramidal crown. Leaves are glossy, elliptical and aromatic. Small crimson flowers are borne in terminal clusters; the unopened flower buds, picked before they open and dried, are the 'cloves' of commerce and the medicinal/culinary part used.[2]
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]
Native to the Maluku Islands (Moluccas, the historic 'Spice Islands') of Indonesia, now cultivated throughout the tropics, notably Zanzibar, Madagascar, Sri Lanka and Indonesia, in warm, humid, well-drained tropical conditions.[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.
Unopened flower buds are hand-picked while still green-pink, just before they would open, then sun-dried until they turn dark reddish-brown - the familiar clove spice.[2]
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]
Clove has an ancient trade history and a long traditional use across Asian, African and European medicine as a dental analgesic (chewed or applied as oil for toothache), a digestive carminative, and an antiseptic. Modern research on its principal constituent eugenol supports strong analgesic, antimicrobial, antioxidant and anti-inflammatory activity, with clove oil remaining a recognised topical dental-pain remedy.[2]
Preparations
Dosage
Clinical trials for osteoarthritis and back pain commonly use extracts providing around 50-60 mg harpagoside daily. Educational reference only, not a prescription.
