Viene anche utilizzato per le emergenze dentali come infiammazioni della bocca o della gola. È stato anche segnalato che l'olio di chiodi di garofano viene utilizzato nella preparazione di alcuni dentifrici e collutori (3). L'eugenolo, un liquido oleoso aromatico estratto dall'olio di chiodi di garofano, è usato come sedativo nelle procedure dentali (4). Il chiodo di garofano ha anche proprietà antiplacca. Può inibire la crescita dei batteri orali che possono causare la placca dentale (5).

È stato anche riscontrato che l'olio essenziale di chiodi di garofano mostra attività anticariogena e citotossica contro un gran numero di patogeni orali (6). L'eugenolo e l'eugenil acetato sono i due componenti attivi nell'olio essenziale di chiodi di garofano che aiutano a prevenire la decalcificazione o l'erosione dentale (7). L'olio di chiodi di garofano è più efficace contro i microrganismi che causano la carie dentale (8).

2. Può aiutare a curare le malattie della pelle e l'acne

Si dice che l'olio di chiodi di garofano agisca contro Propionibacterium acnes, i batteri che causano l'acne (9). Tuttavia, sono necessari ulteriori studi in questa linea per giungere a ulteriori conclusioni.

Uno studio condotto dal Dipartimento di Dermatologia, Il Cairo, Egitto, ha scoperto che l'olio di chiodi di garofano era efficace nel trattamento topico del prurito cronico (10).

Un altro studio condotto dall'ospedale universitario Mansoura, in Egitto, ha scoperto che l'applicazione topica della crema all'olio di chiodi di garofano potrebbe aiutare nel trattamento delle ragadi anali croniche (11).

3. Può avere proprietà analgesiche

È stato scoperto che il massaggio con olio di chiodi di garofano riduce efficacemente il dolore alla schiena nelle madri postnatali (12). Si dice che l'olio di chiodi di garofano possieda proprietà analgesiche che riducono il mal di denti e il dolore articolare attivando i canali del calcio e del cloruro nei linfonodi (13). L'eugenolo contenuto nel chiodo di garofano è stato studiato anche per i suoi effetti analgesici (14). L'olio di chiodi di garofano potrebbe anche alleviare il dolore nei topi (15).

Un altro studio condotto dalla Kuwait University ha scoperto che il gel di chiodi di garofano potrebbe possedere il potenziale per sostituire la benzocaina come anestetico topico (16).

4. Può aiutare la digestione

L'olio di chiodi di garofano può aiutare ad alleviare la nausea, il vomito e la cinetosi, grazie alle sue proprietà antiirritanti e lenitive (17). L'eugenolo nell'olio essenziale di chiodi di garofano ha la capacità di stimolare la sintesi del muco, un importante fattore gastroprotettivo (18). Tuttavia, sono necessarie ulteriori ricerche per comprenderne l'uso nel trattamento delle ulcere gastriche.

5. Può rafforzare il sistema immunitario

L'eugenolo contenuto nei chiodi di garofano protegge le membrane cellulari dai danni dei radicali liberi e dallo stress ossidativo (19). In uno studio su animali, l'olio potrebbe anche esercitare un ruolo protettivo contro lo stress ossidativo indotto dalle radiazioni (20). Si dice che l'olio di chiodi di garofano possieda effetti antiinfiammatori. Uno studio ha mostrato che l'olio di chiodi di garofano ha un effetto antinfiammatorio dose-dipendente sui ratti Wistar (21). Inoltre, è stato riscontrato che l'olio ha effetti antinocicettivi e antipiretici nei topi (22).

6. Può avere proprietà antimicrobiche

L'olio essenziale di chiodi di garofano è una potente fonte di composti antimicrobici che agiscono soprattutto contro i patogeni batterici (23). L'olio può essere efficace nel bloccare la crescita di diversi tipi di batteri e agire anche contro i patogeni delle vie respiratorie (24). È stato anche scoperto che l'olio di chiodi di garofano agisce contro i ceppi clinici di Escherichia coil, un batterio specifico altamente resistente a diversi antibiotici (25). Uno studio condotto dalla sezione di microbiologia e tecnologia dei frutti di mare, in Spagna, ha scoperto che l'olio essenziale di chiodi di garofano uccide efficacemente i biofilm di Staphylococcus aureus (26).

Inoltre, l'olio di chiodi di garofano agisce contro la Candida albicans che causa infezioni da mughetto orale, piede d'atleta e lievito vaginale. L'eugenolo nell'olio di chiodi di garofano potrebbe esercitare un effetto anticandidale (27). Uno studio condotto dalla Toyama Medical and Pharmaceutical University ha scoperto che una combinazione di aciclovir Uno studio condotto dalla Toyama Medical and Pharmaceutical University ha scoperto che una combinazione di aciclovir (un farmaco antivirale) e chiodi di garofano nei topi potrebbe trattare l'infezione virale da herpes simplex (28). Una miscela di oli essenziali con olio di chiodi di garofano potrebbe attenuare in modo significativo il virus dell'influenza. I virus trattati con la miscela di oli avevano un'espressione minima di proteine virali. Ciò significa che l'olio di chiodi di garofano potrebbe avere la capacità di combattere alcuni virus che causano infezioni (29).

7. Può agire come repellente per insetti

L'olio di chiodi di garofano può agire come un repellente per insetti e prevenire le malattie trasmesse da vettori (causate nell'uomo da un parassita) (30). Uno studio ha scoperto che i componenti dell'olio essenziale di chiodi di garofano potrebbero essere potenzialmente utili nella produzione di repellenti per i pidocchi del corpo (31). L'olio di chiodi di garofano potrebbe anche mostrare un'attività repellente contro le termiti giapponesi (32).

Uno studio condotto dalla Mahidol University, Thailandia, ha scoperto che il chiodo di garofano essentialoil potrebbe respingere i chigger di Leptotrombidium, che sono una specie di larve. L'olio potrebbe anche essere un'alternativa più sicura ed economica ai repellenti sintetici che possono causare effetti collaterali (33). L'olio essenziale di chiodi di garofano ha anche mostrato repellenza contro Leptotrombidium deliense, un'altra specie di larve (34). Inoltre, una formulazione contenente olio essenziale di chiodi di garofano è risultata efficace contro la zanzara Aedes aegypti (35).

L'eugenolo nell'olio di chiodi di garofano potrebbe anche funzionare come una promettente alternativa ai comuni insetticidi (36). Si è scoperto che l'eugenolo, l'eugenolo acetato e il beta-cariofillene, le sostanze chimiche bioattive nei chiodi di garofano, hanno la capacità di respingere le formiche del fuoco rosso (37).

8. Può ridurre il dolore allo stomaco

L'eugenolo nell'olio di chiodi di garofano è stato proposto per essere utile per i disturbi gastrointestinali, come il dolore addominale. Viene anche usato per il trattamento di tosse, catarro e congestione toracica (38). Il chiodo di garofano può essere utilizzato per ridurre il dolore allo stomaco. Tuttavia, sono disponibili dati limitati a sostegno di questa affermazione.

9. Può aumentare la salute cardiovascolare

L'olio di chiodi di garofano può aiutare a migliorare la salute cardiovascolare. Tradizionalmente, è noto per migliorare la circolazione sanguigna. Uno studio sui ratti ha mostrato che l'eugenolo nell'olio dilatava le arterie cerebrali. Questo, nell'uomo, può significare un ridotto rischio di ictus (39). Nei ratti, il trattamento con eugenolo potrebbe abbassare i livelli di pressione sanguigna e persino rallentare la frequenza cardiaca (40). In un altro studio, i ratti nutriti con un alto contenuto di fruttosio, quando hanno ricevuto olio essenziale di chiodi di garofano, hanno mostrato un miglioramento della steatosi epatica. L'olio potrebbe anche regolare i livelli di colesterolo nei ratti. Lo studio suggerisce le possibili proprietà cardioprotettive dell'olio di chiodi di garofano (41).

Nei ratti diabetici, l'olio di chiodi di garofano potrebbe anche mostrare effetti cardioprotettivi. Ciò potrebbe essere dovuto alle proprietà antiossidanti dell'olio (42). Un altro studio conclude che l'eugenolo potrebbe essere terapeuticamente utile come agente antipertensivo (43).

10. Può favorire la crescita dei capelli

L'eugenolo è noto per stimolare le radici dei capelli. È stata trovata una formulazione contenente olio di chiodi di garofano per condizionare i capelli e migliorarne la crescita. Potrebbe riparare il fusto del capello (44). Tuttavia, sono necessari ulteriori studi in questa linea per giungere a ulteriori conclusioni.

11. Può avere proprietà antitumorali

L'eugenolo è stato identificato come uno degli agenti che potrebbero avere proprietà antitumorali. Può anche prevenire la proliferazione delle cellule tumorali e può aiutare con la morte delle cellule tumorali (apoptosi) (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 studies on male mice, extracts of clove (along with nutmeg) could enhance sexual behavior (50). 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.

These are the major benefits of clove oil. The oil also has other important uses, which we will explore in the following section.

Other Uses of Clove Oil

• Clove oil blended with cinnamon, orange, nutmeg, or vanilla oils can lift one’s spirits. Using this warming blend in a diffuser will soon fill the room and may also relieve stress.
• Anecdotal evidence suggests that sniffing the spicy aroma of cloves reduces drowsiness and fatigue, irritability, and headaches. It may stimulate the mind and also increase memory recall.
• Cloves encourage the loosening of phlegm from the respiratory system. They also promote sweating during fevers, colds, and flu, which can be very healing. Clove oil is often used in remedies for coughs.
• Like many culinary spices, clove may help relax the smooth muscle lining of the digestive tract. A few drops of the oil in water can relieve nausea. Clove tea may help treat diarrhea, gas, bloating, and intestinal spasms.
• Clove oil stimulates circulation and blood flow to the skin. This may help those with cold extremities.
• Clove oil is as effective as oil of oregano in treating athlete’s foot, nail fungus, and other skin problems. It can be applied directly to the skin or nails (unless the skin is sensitive or broken, wherein it must be diluted with extra virgin olive oil or unrefined coconut oil).
• One drop of clove oil applied to the roof of the mouth may relieve headaches. However, more research is warranted in this regard.
• Clove oil is long used in aromatherapy to relieve pain. For general pain relief, add 3 drops of clove oil to 1 teaspoon of coconut oil or extra virgin olive oil. Apply it to the pain areas.
• A band-aid soaked in a few drops of clove oil can help treat warts. Applying the band-aid to warts may help dissolve them if done regularly for a few weeks.

Clove oil is popularly known as a remedy for toothache. Using oil to relieve tooth pain is simple. Check the following section

How To Use Clove Oil To Treat A Toothache?

Dentists use clove oil as an oral anesthetic and also to disinfect root canals. The oil stops the toothache when dropped into the oral cavity. For temporary relief, dip a cotton swab in clove oil and apply it to the affected tooth. Adding a clove or two to a cup of tea can work miracles on a toothache.

Here is how you can use clove oil to relieve your toothache:

• Dilute a few drops of clove oil in an edible carrier oil, such as olive or coconut oils.
• Dab a clean cotton ball into the solution, and allow it to soak in it.
• Avoiding contact with your gums, apply the cotton ball to the sore tooth. It may take a few minutes of application for you to feel the relief.
• Apply every 2 hours or as necessary.

You can use clove oil in various other ways to achieve its benefits. In the following section we have discussed its most popular uses.

How To Use Clove Oil?

Spray

Using the clove oil as a spray is an easy way to add the clove scent to your room. Clove oil possesses antimicrobial properties, and you can also use it as a mild disinfectant.

To make a clove spray:

• Add several drops of clove oil to water. You would need 10 to 15 drops of clove oil per ounce of water to prepare the spray.
• Add it to a spray bottle. Be sure to shake the bottle well before spraying.

Diffuser

You can also use the oil in a diffuser. While diffusing clove oil, carefully follow the instructions that come with the diffuser. Make sure the room is well-ventilated when you diffuse the clove oil.

Topically

You can apply clove oil to your skin to achieve different benefits.

Massage oils

Use 15 drops of clove oil per ounce of carrier oil to create a 2.5 percent solution of massage oil. This solution can be used as a massage oil for pain relief.

Creams, scrubs, or lotions

For use on normal skin, you need 1 to 2.5 percent dilution of clove oil. For sensitive skin, you need 0.5 to 1 percent dilution of the oil. This diluted solution has no aroma and can be used in the preparation of several scrubs, lotions, or creams.

How Do You Use Clove Oil For Hair Growth?

There is not enough information in this regard. But anecdotal evidence suggests that clove oil acts as a natural remedy to promote hair growth as it contains a number of vital vitamins and minerals. Massaging diluted clove oil into your scalp may boost blood circulation. This could ensure more nutrients and oxygen are supplied to your scalp and hair follicles. To experience the benefits of clove essential oil for hair growth, you can indulge in a hot oil treatment or apply a DIY hair mask prepared with clove oil.

Though clove oil is well studied for its benefits, it may not be suitable for all. The oil may cause side effects in some.

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 (52). 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 (53).

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 (54), (55).

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 products. Contact dermatitis due to this chemical is not unusual. However, true serious allergic reactions are extremely rare (56).

As a primary irritant and sensitizer, eugenol is known to cause contact urticaria as well as chronic urticaria (rashes with dangerous swelling) (57). 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 (58).

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 (59), (60).

Avoid using clove oil if you have had a recent major surgery, peptic ulcers, or bleeding disorders, such as hemophilia.

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.

Conclusion

Clove oil possesses many therapeutic properties and has several health benefits. From dealing with dental problems to treating cardiovascular issues, this essential oil can improve human health in various ways. However, excess usage may cause several side effects. Hence, limit its use and consult your doctor if you experience any adverse effects.
