The clove tree, known as Syzygium aromaticum, is native to Southeast Asia, although today you may find it growing in other locations, too. Clove oil is produced by distilling the dried flower buds that are collected from the clove tree. Other parts of the tree, such as the stem and leaves, may also be used. Clove oil, which ranges in color from colorless to light yellow and has a strong, spicy aroma, has been used for centuries in a variety of applications. In this article, we’ll take a closer look at the potential benefits of this oil and how you can use it at home.
What are the benefits of clove essential oil? Clove oil has traditionally been used for a variety of purposes, including: as an antimicrobial, to help kill bacteria as a pain reliever for conditions such as toothache and muscle pain to relieve respiratory conditions like cough and asthma While many different chemicals have been identified in clove oil, a compound called eugenol is one of the primary components. Like many essential oils, researchers have been working to evaluate the potential health benefits of clove oil and its components. Let’s take a deeper dive into what some of the research says so far. In a study from 2012, researchers found that clove oil had the ability to kill staph bacteria cells in liquid culture and in biofilm. A biofilm is a community of bacteria that lives together, shielded by a protective, slimy film. Most antibiotics aren’t effective at penetrating the biofilm and killing staph bacteria but, according to this study, clove oil seems to be able to. A looked at the antifungal activity of several essential oils. Of the oils tested, clove oil was the most effective at stopping the growth of a range of fungi with environmental origins. In a , researchers investigated the effect of eugenol, a major component of clove oil, on the yeast Candida albicans. This yeast can cause fungal infections such as athlete’s foot, oral thrush, and vaginal yeast infections. According to the authors of the study, eugenol had the ability to kill the yeast, both in culture and in a rat model. A looked at the effect of essential oils on a variety of bacteria that cause respiratory infections, such as pneumonia and influenza. Although the effects were lower than the antibiotics tested, clove oil did have antibacterial activity when added to liquid culture or introduced as a vapor. Clove oil can be effective at stopping the growth of some types of bacteria and fungi. In 2012, investigated the effect of clove oil on the dental erosion of teeth by acidic beverages, like apple juice. Dental erosion of teeth can lead to cavities. According to the study, clove oil and its molecules were effective at preventing dental erosion, leading the authors to believe that clove oil may work in a similar way to fluoride in preventing cavities. A tested 10 natural plant products to see how effective they were against organisms that cause oral cavities. Clove oil was found to be the most effective at inhibiting cavity-causing organisms. A compared the pain-relieving ability of clove gel and benzocaine. Researchers found that participants who were tested with either clove oil or benzocaine had significantly lower pain scores than the placebo group. This led the authors of the study to believe that clove oil may be effective as a topical anesthetic. Clove essential oil may help prevent cavities and relieve oral pain. In 2017, tested clove oil to see whether, when applied to the skin, it had any effect on chronic itching. The study found that, compared to petroleum oil, clove oil significantly relieved itching. A compared the topical use of clove oil cream in the treatment of anal fissures with stool softeners and lignocaine cream. After 3 months, researchers noted healing in 60 percent of people in the clove oil group, compared to only 12 percent in the stool softeners and lignocaine group. When applied to the skin, clove oil may be effective at relieving itching and promoting healing. A looked at the effect that clove oil had on a line of human breast cancer cells in vitro, which means the cells were tested in a dish or test tube. The researchers found that clove oil, in certain quantities, was toxic to the cancer cells. In another , researchers found that clove oil stopped the growth of several cancer cell lines, including but not limited to breast, cervical, and colon cancer. Clove extract also increased cell death and disrupted cell division in a colon cancer cell line. In a test tube, clove oil seems to be effective at killing cancer cells or stopping them from growing. However, further research is needed to investigate clove oil’s anticancer properties.
How to use There are several ways you can use clove oil at home. Here are some suggestions: Using the oil as a spray is an easy way to add the spicy scent of clove to a room. Or perhaps you’d like to make use of clove oil’s antimicrobial properties and use it as a mild disinfectant. To make a clove spray: Add several drops of clove oil to water. The National Association for Holistic Aromatherapy (NAHA) suggests 10 to 15 drops per ounce of water. Since essential oils don’t dissolve in water, you may want to add a dispersing agent such as solubol to the solution as well. Be sure to shake the bottle well before spraying. Like spray applications, using a diffuser can help spread the aroma of clove throughout a room. When diffusing clove oil, be sure to carefully follow the instructions that came with your diffuser.

There are a couple of ways to apply clove oil to your skin if you want to use it for pain relief, wound healing, or to ease itching: Massage oils.

Creams, scrubs, or lotions. Dilute clove oil in an unscented product, such as a lotion or facial cream. The NAHA recommends a 1 to 2.5 percent dilution for normal skin and a 0.5 to 1 percent dilution for sensitive skin. Do you have a toothache? Dabbing clove oil onto your sore tooth may help to relieve the pain until you can get to see a dentist. To use clove oil for a toothache, follow these steps: Dilute a few drops of clove oil in an edible carrier oil, such as olive or coconut oil.
