This means clove oil could have the ability to fight certain viruses that cause infections (29).
7. May Act As An Insect Repellent
Clove oil may act as an insect repellent and prevent vector-borne diseases (caused in humans by a parasite) (30). A study found that the components of clove essential oil could potentially be useful in the production of body lice repellents (31). Clove oil could also show repellent activity against Japanese termites (32).
A study conducted by the Mahidol University, Thailand, found that clove essentialoil could repel Leptotrombidium chiggers, which are a species of larvae. The oil could also be a safer and cheaper alternative to synthetic repellents that may cause side effects (33). Clove essential oil also showed repellency against Leptotrombidium deliense, another species of larvae (34). Also, a formulation containing clove essential oil was found to be effective against the Aedes aegypti mosquito (35).
The eugenol in clove oil could also work as a promising alternative to common insecticides (36). Eugenol, eugenol acetate, and beta-caryophyllene, the bioactive chemicals in clove, were found to have the ability to repel red fire ants (37).

The eugenol in clove oil has been proposed to be beneficial for gastrointestinal complaints, such as abdominal pain. It is also used for treating cough, phlegm, and chest congestion (38). Clove may be used to reduce stomach pain. However, limited data is available to support this claim.
9. May Boost Cardiovascular Health
Clove oil may help boost cardiovascular health. Traditionally, it is known to improve blood circulation.
A rat study showed that the eugenol in the oil dilated cerebral arteries. This, in humans, may mean a reduced risk of stroke (39). In rats, treatment with eugenol could lower blood pressure levels and even slow down the heart rate (40). In another study, high-fructose-fed rats, when given clove essential oil, showed an improvement in fatty liver. The oil could also regulate cholesterol levels in the rats. The study suggests the possible cardioprotective properties of clove oil (41).
In diabetic rats, clove oil could also show cardioprotective effects. This could be because of the oil’s antioxidant properties (42). Another study concludes that eugenol could be therapeutically useful as an antihypertensive agent (43).

11. May Have Anticancer Properties
Eugenol was identified as one of the agents that could have anticancer properties. It may also prevent the proliferation of cancer cells and can help with cancer cell death (apoptosis) (45).
In another study, eugenol could suppress the growth of melanoma or skin cancer. Eugenol treatment could reduce tumor size by 40% and also delayed the growth of tumors (46). The National Toxicology Program based on several long term carcinogenicity studies concluded that eugenol was not carcinogenic to rats (47). Similar observations could be expected in humans as well.
In another study, clove extract was found to inhibit tumor growth. It could be a novel treatment for colorectal cancer (48).
However, it is important to practice caution, as eugenol may also have certain prooxidant properties. The compound may cause allergies and other inflammatory reactions (49).
12. May Act As An Aphrodisiac

In another study, 50% ethanolic extract of clove produced a significant and sustained increase in the sexual activity of normal male rats. The extract also caused no adverse effects (51). However, more studies are warranted in this regard.
13. May Treat Sore Throat
Clove is a natural spice that has been used to provide relief from streptococcal pharyngitis, an infection that causes sore throat. It contains eugenol that has both anti-inflammatory and analgesic properties, which may help reduce the pain associated with sore throat (52).

Are There Any Side Effects Of Using Clove Oil?
Clove oil may cause local irritation, rare allergic reactions, and contact dermatitis in some individuals. More severe effects include tissue injury and acute onset of seizures, coma, and damage to the liver and kidneys (54). Clove essential oil is generally recognized as a safe substance when consumed in concentrations lower than 1500 mg/kg. The World Health Organization (WHO) established that the daily quantity acceptable of clove per day is 2.5 mg for every kg of body weight in humans (55).
Hepatotoxicity
High doses of eugenol may harm the liver and kidneys, as per some rat studies. Several instances of severe acute liver and kidney injury have been reported after an accidental overdose of eugenol containing herbal products, largely in infants (56), (57).
May Cause Skin irritation
Excess usage of clove oil can cause skin irritation in some people. Eugenol is an effective substance that is incorporated into many dental care products. Contact dermatitis due to this chemical is not unusual. However, true serious allergic reactions are extremely rare (58).
As a primary irritant and sensitizer, eugenol is known to cause contact urticaria as well as chronic urticaria (rashes with dangerous swelling) (59). If you are concerned about your sensitivity to this essential oil, do a patch test before using it. Apply a small amount of diluted clove oil to the inside of your elbow. If you notice signs of skin irritation, like redness, itching, or swelling, don’t use clove oil topically.
May Cause Allergies
It is very rare to have an allergic reaction due to clove oil. The eugenol in the oil may cause oral irritation and heat sensation on the tongue (60).
Drug Interactions
Medications that slow blood clotting (anticoagulant/antiplatelet drugs) interact with clove. Hence, avoid using clove oil if you are taking any anticoagulants. Acetyl eugenol, a component of clove oil (Syzygium aromaticum L.), inhibits platelet aggregation in humans. This could lead to bleeding (61), (62).
Avoid using clove oil if you have had a recent major surgery, peptic ulcers, or bleeding disorders, such as hemophilia.
Even though clove oil has numerous health benefits, it is important to be aware of any possible negative effects and adopt the appropriate safety measures to ensure healthy consumption. Scroll down to know more.
Precautions
When using clove oil, it is important to keep the following precautions in mind:
- Always perform a patch test on a small section of skin before topically applying clove oil to figure out any allergic reactions or sensitivities.
- Undiluted clove oil may damage or irritate skin. So avoid applying it directly on the skin. It should be diluted with a carrier oil, such as olive or coconut.
- Since ingesting clove oil can be dangerous, keep it in a safe location out of children’s reach.
- Ensure that clove oil does not come into contact with the eyes, as it can cause irritation.
- If you are pregnant, nursing, or have a medical condition, consult a healthcare provider before using clove oil.
You can buy clove oil from your nearest health store. But before you make a purchase, you need to keep a few things in mind.
What To Look For When Buying Clove Oil
Look for a purity statement on the label
Try to buy 100 percent clove essential oil and look for other ingredients listed (if any).
Don’t go by the marketing hype
Generally, essential oils are not regulated by the Food and Drug Administration (FDA) in the same way as drugs. Hence, you should be more cautious of any oil that claims to cure a specific condition.
Make sure the clove oil is in a dark glass bottle
Light has the potential to damage essential oils. Dark glass helps keep the light out. Always ensure your product comes packaged in a dark glass bottle.
If you can, smell it before buying it
Clove essential oil has a unique fragrance. Smell it before buying. If it does not smell natural, avoid purchasing it.
