Clove Essential Oil: What You Should Understand

Clove oil is an essential oil obtained from the clove tree, scientifically known as Syzygium aromaticum. This plant originates from Southeast Asia, although it is now cultivated in various regions around the world.

The oil is produced through the distillation of dried flower buds harvested from the tree. In some cases, other parts such as the stems and leaves are also used. Clove oil typically ranges in color from clear to pale yellow and is recognized for its strong, warm, and spicy fragrance. For centuries, it has been utilized for numerous traditional and medicinal purposes.

Benefits of Clove Essential Oil

Historically, clove oil has been used in several ways, including:

• As an antimicrobial agent to help eliminate bacteria
• As a natural pain reliever, particularly for toothaches and muscle discomfort
• To ease digestive issues
• To help relieve respiratory problems such as coughs and asthma

One of the main active compounds in clove oil is eugenol, which is believed to contribute significantly to its therapeutic effects. Researchers have been studying this compound and the oil itself to better understand their potential health benefits.

Antimicrobial Properties

A 2012 study found that clove oil could effectively destroy staph bacteria, both in liquid cultures and within biofilms—protective layers that make bacteria more resistant to antibiotics. Interestingly, clove oil showed an ability to penetrate these biofilms.

In another study from 2017, clove oil demonstrated strong antifungal properties, outperforming other essential oils in inhibiting the growth of various environmental fungi.

Research conducted in 2005 focused on eugenol’s effect on Candida albicans, a yeast responsible for infections like oral thrush and vaginal yeast infections. The findings showed that eugenol could effectively kill this yeast in both laboratory and animal models.

A 2018 study also explored clove oil’s antibacterial effects on pathogens linked to respiratory infections such as pneumonia and influenza. Although it was less potent than standard antibiotics, it still demonstrated noticeable antibacterial activity, especially when used in vapor form.

Dental Benefits

Clove oil has long been associated with oral health. A 2012 study suggested that it may help prevent tooth enamel erosion caused by acidic beverages, potentially offering protective effects similar to fluoride.

In a 2016 study comparing natural substances, clove oil proved to be the most effective at inhibiting bacteria responsible for tooth decay.

Additionally, a 2006 study compared clove oil gel to benzocaine for pain relief. The results indicated that both significantly reduced pain compared to a placebo, suggesting clove oil may serve as an effective topical anesthetic.

Skin Applications

Clove oil may also provide benefits when applied to the skin. A 2017 study showed that it could significantly reduce chronic itching compared to petroleum-based products.

Another study from 2007 examined its use in treating anal fissures. After three months, about 60% of participants using clove oil cream experienced healing, compared to only 12% in the group using stool softeners and lignocaine cream.

Overall, research continues to support the potential of clove oil as a versatile natural remedy, although further studies are needed to confirm and expand upon these findings.

How to Use Clove Oil

Clove oil can be used at home in several practical ways. Here are some common methods:

Spray
Using clove oil as a spray is a simple way to bring its warm, spicy aroma into a room. It can also be used as a mild disinfectant due to its antimicrobial properties. To make a spray:

• Add a few drops of clove oil to water. The National Association for Holistic Aromatherapy (NAHA) recommends about 10–15 drops per ounce of water.
• Since essential oils don’t mix well with water, consider adding a dispersing agent like solubol.
• Shake the bottle thoroughly before each use.

Diffusion
A diffuser can help distribute the scent of clove oil throughout a space. Always follow the instructions provided with your diffuser. Make sure the room is well-ventilated when diffusing or spraying clove oil.

Topical Application
If you want to apply clove oil to the skin for pain relief, wound care, or itch reduction, proper dilution is important:

• Massage oils: Mix clove oil with a carrier oil such as jojoba, coconut, or olive oil. NAHA suggests about 15 drops per ounce of carrier oil (around a 2.5% dilution).
• Creams or lotions: Add clove oil to unscented skincare products. Use a 1–2.5% dilution for normal skin and 0.5–1% for sensitive skin.

Dental Use
Clove oil is often used for temporary relief of toothache. To use it:

• Dilute a few drops of clove oil in an edible carrier oil like coconut or olive oil.
• Soak a clean cotton ball in the mixture.
• Gently apply it to the affected tooth, avoiding the gums.
• Relief may take a few minutes. Reapply every couple of hours if needed.
• Stop use if irritation occurs.

Possible Side Effects

While clove oil offers many benefits, it may also cause side effects:

Skin Irritation
Some individuals may experience irritation. To test sensitivity, apply a small amount of diluted oil to the inside of your elbow. If redness, itching, or swelling occurs, avoid using it on your skin.

Allergic Reactions
Although uncommon, allergic reactions can happen. Be aware of symptoms of severe reactions (anaphylaxis), such as:

• Rash or hives
• Difficulty breathing
• Wheezing or coughing
• Tightness in the throat or trouble swallowing
• Digestive issues like vomiting or diarrhea
• Fainting

Drug Interactions
Avoid using clove oil if you are taking:

• Blood thinners (anticoagulants)
• Monoamine oxidase inhibitors (MAOIs)
• Selective serotonin reuptake inhibitors (SSRIs)

Certain Health Conditions
It’s best not to use clove oil if you:

• Have recently undergone major surgery
• Suffer from peptic ulcers
• Have bleeding disorders such as Hemophilia

Tips for Buying Clove Oil

To ensure you’re purchasing a high-quality product, keep these points in mind:

• Check for the scientific name Syzygium aromaticum on the label. It may also appear as Eugenia caryophyllata.
• Look for products labeled as 100% pure clove essential oil, with all ingredients clearly listed.
• Be cautious of exaggerated marketing claims, as essential oils are not regulated like medications by the Food and Drug Administration.
• Choose oils stored in dark glass bottles to protect them from light damage.
• If possible, smell the oil before buying—it should have a strong, characteristic spicy aroma.

The Bottom Line

Clove oil has long been used to help relieve digestive discomfort, reduce pain, and support respiratory health. Research also suggests it may be beneficial for oral care, skin applications, and fighting certain infections, with potential ongoing studies into its role in cancer research.

As with any essential oil, safe usage is essential. If you have health conditions, are taking medication, or are unsure about its use, consult a healthcare professional before using clove oil.
