Do you know that clove oil has been treasured for centuries across diverse cultures for its remarkable healing properties and distinctive aroma? This potent essential oil carries a rich history dating back to ancient Chinese and Indian civilizations, where it was prized not only as a culinary spice but as a powerful medicinal remedy.
In recent years, scientific research has begun to validate what traditional healers have known for generations—clove oil offers an impressive array of health benefits. This article will explore 18 amazing benefits of clove oil, with its potential side effects. In addition, we will also discuss practical ways to incorporate this versatile oil into your daily wellness routine.

What Is Clove Oil?
Clove oil is a concentrated essential oil extracted primarily from the dried flower buds (cloves) of the Syzygium aromaticum tree. It is native to Indonesia’s Maluku Islands, historically known as the Spice Islands. This evergreen tree can grow up to 40 feet tall. It can produce small, reddish-brown flower buds that are harvested before they bloom and then dried until they turn dark brown.
The extraction of clove oil typically happens through steam distillation, a process that captures the volatile compounds responsible for the oil’s therapeutic properties and distinctive warm, spicy aroma.
The main active component of clove oil is eugenol, making up approximately 70-90% of its composition. Eugenol is largely responsible for many of the oil’s medicinal properties, including its analgesic (pain-relieving), anti-inflammatory, and antimicrobial effects.
There are actually three types of clove oil:
- Bud oil: Extracted from flower buds, considered the highest quality
- Leaf oil: Made from clove leaves, it contains slightly less eugenol
- Stem oil: Derived from the stems, it contains the least amount of eugenol
Historically, cloves and their oil have been used for over 2,000 years in Chinese and Indian traditional medicine. Ancient texts mention cloves for treating digestive issues, toothaches, and respiratory conditions.
Today, clove oil remains an important component in modern aromatherapy, dentistry, and natural medicine practices worldwide.

18. Cancer-Fighting Potential
Emerging research is investigating the potential anti-cancer properties of compounds found in clove oil, particularly eugenol. Laboratory studies have found that eugenol showed cytotoxic effects against several cancer cell lines, including breast, cervical, and colon cancers.
The mechanisms behind these effects appear to involve inducing apoptosis in cancer cells and inhibiting cancer cell proliferation. Additionally, the powerful antioxidant properties of clove oil may help prevent the DNA damage that can lead to cancer initiation.
While these laboratory findings are promising, it’s important to note that research is still preliminary, and most studies have used isolated compounds rather than whole clove oil.

Potential Side Effects and Precautions
Despite its many benefits, clove oil is extremely potent and can cause adverse reactions if used improperly. Here are important precautions to consider:
1. Skin Irritation and Sensitivity
Undiluted clove oil can cause severe skin irritation, a burning sensation, and even chemical burns when applied directly to the skin. Always dilute clove oil in a carrier oil (like coconut, olive, or jojoba oil) before topical application. A safe dilution is typically 0.5-1% (3-6 drops per ounce of carrier oil).
Always perform a patch test before using clove oil topically, even when diluted. Apply a small amount of diluted oil to the inside of your forearm and wait 24 hours to check for any adverse reactions.
2. Oral Tissue Sensitivity
While clove oil is famous for dental pain relief, it can actually damage gum tissues and tooth pulp if used undiluted. When using for a toothache, apply only a tiny amount of diluted oil using a cotton swab.
Prolonged direct contact with oral mucous membranes can cause tissue damage and increased sensitivity over time. Use clove oil for oral health intermittently rather than daily for extended periods. Children and those with existing oral conditions should use particularly diluted preparations or seek alternative remedies.
3. Internal Consumption Risks
Pure clove essential oil should not be ingested in its concentrated form. Ingestion of undiluted clove oil can cause liver damage, blood disorders, and severe digestive issues, including burning of the throat, vomiting, and diarrhea.
If a recipe calls for clove oil for flavoring, ensure you’re using food-grade clove oil specifically labeled for culinary use, which is significantly less concentrated than essential oil. Even then, use only a tiny amount—typically just a drop or two for an entire dish.
4. Pregnancy and Breastfeeding Concerns
Pregnant women should avoid using clove oil throughout pregnancy. The stimulating effects of clove oil could potentially affect uterine contractions, and there’s insufficient research establishing its safety during pregnancy.
Breastfeeding mothers should also exercise caution, as components of clove oil could potentially pass into breast milk. If using clove oil while breastfeeding, avoid application near the breast area and wash hands thoroughly after handling.
5. Interaction with Medications
Clove oil may interact with several types of medications, including:
- Blood thinners (like warfarin or aspirin)
- Diabetes medications (may enhance blood sugar-lowering effects)
- Antidepressants, particularly MAOIs
- Anticonvulsant drugs
Anyone taking prescription medications should consult their healthcare provider before using clove oil, even topically, as some components can be absorbed through the skin.
6. Special Precautions for Children
Clove oil is not recommended for use on children under age 2. For older children, use only highly diluted preparations (0.25% or less) and only when necessary.
Never apply clove oil near a child’s nose or mouth, as inhalation of the concentrated oil can cause breathing difficulties. Keep all essential oils, including clove oil, stored safely away from children’s reach.
