Chapter 1 — What Is Clove? Origin and Botanical Background

1.1 Origins and Botanical Identity

Clove (Syzygium aromaticum (L.) Merr. & L.M.Perry) belongs to the Myrtaceae family and is an evergreen tree reaching 8–12 meters (25–40 feet) in height. The spice consists of the dried reddish-brown flower buds harvested before flowering. The tree is indigenous to the Maluku Islands (Spice Islands) of Indonesia, though it is now cultivated across tropical regions including Madagascar, Comoros, Tanzania, Sri Lanka, and India. Flowering typically begins around the fifth year of growth, with a mature tree producing up to 75 pounds (34 kg) of dried buds annually.

Historical significance at a glance

• As early as 200 BCE, envoys from Java brought cloves to China's Han dynasty court, where buds were held in the mouth to perfume breath during imperial audiences.
• By the 10th–12th centuries, cloves were traded at Sri Lanka's ancient port of Mantai, a key hub in the Indian Ocean spice route connecting Southeast Asia with Arabia, India, and Rome.
• The 18th-century French smuggling of clove seeds from the East Indies broke the Dutch monopoly, establishing plantations in Seychelles and Zanzibar.
• Indonesia remains the world's largest clove producer as of 2021, followed by Madagascar, Comoros, Tanzania, and Sri Lanka.

2.1 Culinary Applications and Forms

Cloves deliver intense warmth with notes of bitterness and sweetness, requiring only small quantities due to their pungency. The spice is available in whole and ground forms, with whole cloves maintaining flavor longer and typically removed before serving as they remain woody after cooking. Ground cloves integrate directly into recipes for even distribution. Cloves appear across global cuisines in both savory and sweet applications.

Primary culinary uses include:

• Spice blends: Core component of Chinese five-spice powder (with fennel, cassia, star anise, and Sichuan pepper), garam masala, and pumpkin pie spice.
• Beverages: Infused into mulled wine, wassail, chai tea, cider, and hot toddies.
• Meat dishes: Studded into baked ham, incorporated into meat rubs and marinades, and featured in lamb korma.
• Baked goods and sauces: Flavoring gingerbread, mincemeat, and various holiday fare.
• Rice and savory dishes: Added to Indian rice preparations and Vietnamese pho.

Substitution note: Allspice serves as the closest substitute, replacing clove in equal measure. For ground clove alternatives, combine equal parts ground nutmeg and cinnamon.

Chapter 3 — Medicinal Properties and Health Benefits

3.1 Documented Therapeutic Applications

Clove has been used in Traditional Chinese Medicine, Ayurveda, Islamic Traditional Medicine, and Western herbalism for centuries. The primary bioactive compound, eugenol (constituting 14–20% of essential oil and up to 53.24% of aqueous extracts), exhibits anti-inflammatory, antibacterial, antioxidant, and analgesic properties. Research has investigated clove's effects across multiple health domains with varying levels of evidence.

Summary of reported medicinal benefits:

• Oral health: Clove oil or eugenol may reduce dental bacteria, numb gums, and ease toothaches. One older study found clove oil gel comparable to benzocaine for numbing before dental procedures. Clove oil appears in temporary dental fillings and mouthwash formulations.
• Digestive aid: Cloves are traditionally used to relieve nausea, vomiting, bloating, and indigestion in multiple medical systems.
• Antimicrobial activity: Research published in 2025 demonstrated clove aqueous extract exerted potent activity against 10 bacterial strains including E. coli (33mm inhibition zone), K. pneumoniae (32mm), and MRSA (29mm). Eugenol contributes significantly to antibacterial, antifungal, and insecticidal properties.
• Respiratory relief: Traditional practices include chewing cloves for sore throats and coughs, or inhaling steam from boiled cloves to open nasal passages during colds.
• Pain and inflammation: External application of clove oil may help ease headaches and muscle pain, supported by eugenol's anti-inflammatory mechanisms.
• Neuroprotective potential: A 2024 bibliometric review suggested clove components (eugenol, β-caryophyllene) exhibit antioxidant and anti-inflammatory effects that may protect brain function, with possible mood-enhancing properties via neurotransmitter modulation.
• Liver protection: An animal study reported that an eugenol-rich fraction of clove reversed biochemical and histopathological signs of liver cirrhosis, reducing oxidative stress and inhibiting hepatic cell proliferation.

Note on evidence strength: While laboratory and animal studies show promise, the Cleveland Clinic notes limited human clinical trials exist. Many studies used concentrated compounds that would be toxic if consumed in equivalent amounts by humans. Clove as a food spice is safe, but medicinal applications require caution.

Chapter 4 — Scientific Evidence: Bioactive Compound Eugenol

⬅ Back to Table of Contents

4.1 Pharmacological Research and Emerging Applications

Eugenol (C10H12O2) is the principal bioactive compound in clove essential oil, typically comprising 14–20% of the dried bud by weight. Recent research has elucidated its mechanisms of action across multiple biological activities. A 2025 study published in the NIH database found that Syzygium aromaticum essential oil demonstrated strong antioxidant, antibacterial, antifungal, and insecticidal properties, with eugenol identified as the primary driver of antioxidant and insecticidal effects through single-electron transfer mechanisms comparable to ascorbic acid in polar media.

Additional evidence from recent studies:

• Antiviral research (2025): Molecular docking studies revealed eugenol and β-caryophyllene from clove bind strongly to multiple SARS-CoV-2 proteins including the envelope protein (−5.267 kcal/mol) and RdRp (−6.200 kcal/mol). Pharmacokinetic profiling indicated favorable absorption and low toxicity profiles, suggesting potential as multi-target antiviral candidates pending clinical verification.
• Antioxidant mechanisms: Density functional theory calculations confirmed eugenol's antioxidant activity operates through single-electron transfer from its deprotonated state, explaining its efficacy in biological systems.
• Food preservation: Clove oil and eugenol serve as natural food preservatives, offering advantages over synthetic alternatives like sodium benzoate due to antibacterial activity, fragrance, and safety profile.
• Cosmetic and pharmaceutical uses: Clove essential oil is incorporated into toothpaste, mouthwash, antiseptics, perfumes, soaps, and anti-inflammatory cosmetic preparations. Eugenol also aids skin permeation of drugs and serves in vanillin synthesis.

Chapter 5 — Safety, Side Effects, and Precautions

5.1 Known Risks and Contraindications

While cloves are safe as a culinary spice in typical food amounts (small quantities), concentrated clove products and essential oil carry significant risks. The Cleveland Clinic emphasizes that clove oil can be toxic when ingested, and children consuming even small amounts risk liver damage and seizures. Clove oil applied to gums may cause burning and inflammation despite its numbing effects.

Absolute contraindications and precautions:

• Pregnancy and breastfeeding: No safety data exists for clove products or supplements. Food amounts are likely safe, but medicinal use should be avoided.
• Blood thinners and bleeding disorders: Eugenol affects blood clotting ability. Combining with anticoagulants (warfarin) or aspirin may cause serious bleeding complications.
• Surgery: Cloves can affect blood sugar levels and blood clotting post-surgery. Discontinue use at least two weeks before scheduled procedures.
• Diabetes and insulin use: Combining eugenol with insulin medications may cause dangerously low blood sugar (severe hypoglycemia).
• Clove water: Not recommended due to unknown eugenol concentrations and lack of evidence for benefits.

Cleveland Clinic specialist advice: Functional medicine specialist Dr. Erik Modlo states, "There isn't enough scientific evidence to support clove use for medicinal purposes" despite traditional applications. He recommends obtaining nutrients from food sources rather than clove supplements or concentrated products.

FAQ

Is it safe to drink clove water daily?

Medical experts advise against drinking clove water regularly because there is no way to determine how much eugenol you consume, and no scientific evidence supports its health benefits. Clove water likely has higher compound concentrations than traditional spiced beverages, increasing toxicity risk.
