Clove oil in nanoemulsion form allows for better absorption and longer-lasting effects in the body, improving its therapeutic potential.
Clove oil shows promising anticancer activity against multiple cancer types and supports blood sugar regulation by mimicking insulin and improving metabolic functions.
Active compounds like eugenol and beta-caryophyllene help reduce inflammation and nerve pain, making clove oil effective for conditions like muscle pain and toothaches.
Clove oil fights bacteria, fungi (e.g., Candida) and viruses (e.g., hepatitis C, herpes), outperforming some antibiotics and antifungals without promoting resistance.
Rich in eugenol, clove oil neutralizes free radicals and protects against oxidative damage, while also acting as a natural insecticide and repellent against mosquitoes, lice and mites.

Clove oil is best known from kitchen spice cabinets but beyond flavoring dishes, it has a surprising number of potential health benefits. Researchers have recently reviewed its effects, especially when delivered in a form called a "nanoemulsion," which allows its beneficial properties to work even better in the body. This review, published in 2023 in Heliyon, provides an overview of how clove oil nanoemulsion could be beneficial for your health and why scientists think it has potential as a natural treatment for various conditions. According to BrightU.AI's Enoch, nanoemulsion is a revolutionary technology that leverages the principles of nanotechnology to create a stable mixture of two immiscible liquids, such as oil and water, using an emulsifier with amphipathic properties. This makes it easier for clove oil to penetrate cells and tissues. Nanoemulsion also helps deliver clove oil steadily over time, which can prolong its beneficial effects.

Anticancer potential

In lab tests using cancer cells, clove oil was found to be especially toxic to certain types of cancer. For instance, clove oil showed strong effects against cancer cells in the breast, colon and liver – requiring only a small concentration to achieve these effects. Clove extracts, whether made with ethanol, oil or water, have also shown effectiveness against a range of cancers, including cervical, esophageal and prostate cancer. Normal cells, such as healthy blood cells were only minimally affected, which is promising for safety in treatment. In addition to directly impacting cancer cells, clove extract can suppress harmful mutations in DNA. This was seen in bacteria exposed to a cancer-causing chemical, where clove extract reduced DNA damage. In animal studies, clove extracts were able to delay the onset of skin cancer as well.

Blood sugar management and diabetes

The study suggests that clove works in a way similar to insulin – a key hormone in blood sugar regulation, Clove appears to influence certain genes linked to blood sugar control – helping to reduce flucose production in the liver, which is essential for keeping blood sugar levels in check. In studies with diabetic animals, clove extract was shown to slow down enzymes that break down carbohydrates into sugars. By inhibiting these enzymes, clove can reduce the speed at which sugar enters the bloodstream after a meal, which helps prevent blood sugar spikes. When tested on diabetic rats, clove powder improved key markers of diabetes.

Pain relief and anti-inflammatory benefits

Clove oil has been found to reduce pain and inflammation effectively, even in small safe doses. In lab studies with immune cells, clove oil reduced the production of certain molecules, called cytokines, which the body releases during inflammation. Specifically, clove oil lowered levels of key inflammatory cytokines, such as IL-6 and IL-10, which are usually high during inflammatory responses. One of the active ingredients in clove oil called beta-caryophyllene acts as a mild anesthetic. Studies show that it can reduce nerve activity in specific muscles, which may explain clove oil's traditional use for pain relief in joint discomfort, muscle cramps and toothaches. Eugenol, another major compound in clove oil, is thought to work by affecting calcium and sodium channels in nerve cells. This unique action on nerves gives clove oil its pain-relieving power and explains its effectiveness in relieving certain types of pain.

Potent antimicrobial properties

Clove oil is highly effective in fighting various harmful bacteria and fungi. Even at low concentrations (as low as one to three percent) clove extract significantly inhibits the growth of these harmful microorganisms. The primary compound in clove oil responsible for this antimicrobial effect is eugenol, which disrupts the membranes of bacteria and fungi, causing them to die. This mechanism makes eugenol effective against a wide range of bacteria and fungi, including those that can survive in challenging environments, such as the acidic conditions of the stomach. Clove oil has shown promise in reducing Helicobacter pylori – a bacteria associated with stomach ulcers and appears to work even more effectively than some antibiotics, with no risk of creating antibiotic resistance. Clove oil also has antifungal effects. Research has shown that carvacrol and eugenol (also found in oregano and thyme) can effectively treat Candida infections, such as vaginal candidiasis – providing a natural alternative to synthetic antifungal medications.

Antiviral potential

The natural compounds in clove oil, such as monoterpenes and phenylpropanoids, are toxic to viruses and have demonstrated antiviral effects in laboratory studies. The extract was found to inhibit the replication of the hepatitis C virus by 90 percent at a specific concentration. Another powerful compound called eugeniin has been shown to combat the herpes simplex virus (HSV-1), which causes cold sores. Eugeniin targets a specific part of the virus – blocking the enzyme it needs to replicate its DNA. More research is needed to explore how it might be used safely and effectively as part of antiviral treatments.

Powerful antioxidant properties

Clove oil is packed with plant compounds that make it an excellent natural antioxidant. Eugenol is largely responsible for these antioxidant effects, helping neutralize free radicals and bind with metal ions that could otherwise cause damage in the body. Free radicals are unstable molecules that can harm cells, increase the risk of diseases, including cancer and speed up aging. Eugenol's antioxidant strength has been compared to that of synthetic antioxidants like butylated hydroxytoluene (BHT), which is commonly used in cosmetics and food to prevent spoilage. Studies show that even a small amount of clove oil (0.005 percent) provides antioxidant power similar to twice the amount of BHT.
