Key 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
Improves glycemic control in type 2 diabetes - lowers fasting blood glucose and HbA1c
Anti-inflammatory and antioxidant; Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic)
Digestive support / mild dyspepsia (traditional)
Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic); May improve liver enzymes and hepatic fat in non-alcoholic fatty liver disease (NAFLD); Supports liver recovery and 'detox' (traditional framing of the hepatoprotective action)

Safety, Cautions & Contraindications
Very well tolerated, even at high doses; the main effects are mild gastrointestinal upset (nausea, loose stools). As a member of the daisy family (Asteraceae), it can cause allergic reactions in sensitive people.
Has a low potential for drug interactions (little effect on liver CYP enzymes), but use caution with medicines that have a narrow therapeutic window. Human pregnancy data are limited, so use cautiously.
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
Robust biennial (occasionally annual) thistle (Asteraceae), 30-150 cm tall. Leaves are glossy dark green with distinctive white marbled veining (the 'milk' of legend), spiny-margined and deeply lobed. Large, solitary, purple-pink thistle-type flower heads are surrounded by spiny bracts, followed by shiny, mottled brown-black seeds - the part used.[12]
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 Mediterranean region, now naturalised worldwide on disturbed, sunny ground - roadsides, waste places and dry pastures - and widely cultivated commercially for its seed.[12]
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
Seed heads are harvested once fully dry (late summer), and the seeds (fruit) are threshed out.[12]
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
Milk thistle has a very long European folk-medicine tradition, documented since antiquity, as a liver tonic, and its seed extract, standardised to the flavonolignan complex silymarin, is one of the most extensively studied herbal hepatoprotectants. Modern research supports antioxidant, anti-inflammatory and liver-protective activity, with growing interest in metabolic/blood-sugar effects.[12, 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]
