Mitkä ovat neilikkaöljyn terveyshyödyt ja käyttö?

Kynsiöljy uutetaan neilikkapuusta. Se on höyry tislattu neilikan silmuista, joilla on terävä pistävä haju. Se on kotoisin Kaakkois-Aasiasta ja sitä on käytetty vuosisatojen ajan hammasongelmiin liittyvän kivun hoitoon.

Kynsiöljyllä sanotaan olevan antioksidantteja, antimikrobisia, sienilääkkeitä, anti-inflammatorisia ja anestesia-ominaisuuksia (1), (2). Se voi myös auttaa hoitamaan ihovaivoja, helpottamaan ruoansulatusta ja parantamaan immuunijärjestelmää. Tässä artikkelissa käsitellään neilikkaöljyn mahdollisia terveysvaikutuksia, käyttötarkoituksia ja sivuvaikutuksia. Lue lisätietoja.

12 kynsiöljyn käyttöä ja hyötyä

1. Voi lievittää hammassärkyä

Kynsi eteerinen öljy voi auttaa estämään onteloita ja lievittää suun kipua. Perinteisesti sitä käytetään hampaiden lievittämiseen. Sitä käytetään myös hampaiden hätätilanteissa, kuten suun tai kurkun tulehduksessa. Kynsiöljyä on raportoitu käytetyn myös tiettyjen hammastahnojen ja suuveden valmistuksessa (3). Kynsiöljystä uutettua aromaattista öljyistä nestettä Eugenolia käytetään rauhoittavana aineena hammashoitoissa (4). Neilikalla on myös plakkia estäviä ominaisuuksia. Se voi estää suun bakteerien kasvua, jotka voivat aiheuttaa hammasplakkia (5).

Kynsi-eteerisellä öljyllä havaittiin myös olevan antikariogeeninen ja sytotoksinen aktiivisuus suurta määrää oraalisia taudinaiheuttajia vastaan ​​(6). Eugenoli ja eugenyyliasetaatti ovat neilikan eteerisen öljyn kaksi aktiivista komponenttia, jotka auttavat estämään kalkinpoistoa tai hampaiden eroosiota (7). Kynsiöljy on tehokkain mikro-organismeja vastaan, jotka aiheuttavat karieksen (8).

2. Voi auttaa hoitamaan ihosairauksia ja aknea

Kynsiöljyn sanotaan toimivan Propionibacterium acnesia, bakteereja, jotka aiheuttavat aknea (9). Lisää johtopäätöksiä tarvitaan kuitenkin tällä rivillä.

Kairon, Egyptin ihotautien osaston tekemässä tutkimuksessa todettiin, että neilikkaöljy oli tehokas kroonisen kutinan paikallishoidossa (10).

Toisessa Egyptin Mansouran yliopistollisen sairaalan tutkimuksessa todettiin, että neilikkaöljyvoiteen paikallinen käyttö saattaa auttaa kroonisten peräaukon halkeamien hoidossa (11).

3. Voi olla kipua lievittäviä ominaisuuksia

Kynsiöljyhieronnan havaittiin vähentävän tehokkaasti selkäkipuja synnytyksen jälkeisillä äideillä (12). Kynsiöljyllä sanotaan olevan kipua lievittäviä ominaisuuksia, jotka vähentävät hammassärkyä ja nivelkipua aktivoimalla imusolmukkeiden kalsium- ja kloridikanavat (13). Neilikan eugenolia on tutkittu myös sen analgeettisten vaikutusten suhteen (14). Kynsiöljy voi myös lievittää kipua hiirillä (15).

Toisessa Kuwaitin yliopiston suorittamassa tutkimuksessa havaittiin, että neilikkageelillä saattaa olla potentiaalia korvata bentsokaiini ajankohtaisena anestesia-aineena (16).

4. Toukokuu Ruuansulatus

Kynsiöljy voi auttaa lievittämään pahoinvointia, oksentelua ja liikesairautta ärsyttävien ja rauhoittavien ominaisuuksiensa ansiosta (17). Neilen eteerisen öljyn eugenolilla on kyky stimuloida liman synteesiä, joka on tärkeä gastroprotektiivinen tekijä (18). Lisätutkimuksia tarvitaan kuitenkin sen ymmärtämiseksi mahahaavojen hoidossa.

5. Voi lisätä immuunijärjestelmää

Neilikan eugenoli suojaa solukalvoja vapaiden radikaalien vaurioilta ja oksidatiiviselta stressiltä (19). Yhdessä eläintutkimuksessa öljyllä voi olla myös suojaava tehtävä säteilyn aiheuttamalta oksidatiiviselta stressiltä (20). Kynsiöljyllä sanotaan olevan anti-inflammatorisia vaikutuksia. Tutkimus osoitti neilikkaöljyä, jolla oli annoksesta riippuvainen anti-inflammatorinen vaikutus Wistar-rotilla (21). Öljyllä havaittiin myös olevan antiinosiseptiivisiä ja antipyreettisiä vaikutuksia hiirissä (22).

6. Voi olla antimikrobisia ominaisuuksia

Kynsi-eteerinen öljy on voimakas antimikrobisten yhdisteiden lähde, jotka vaikuttavat erityisesti bakteerien patogeeneihin (23). Öljy voi olla tehokas pysäyttämään monentyyppisten bakteerien kasvun ja toimimaan myös hengitysteiden patogeenejä vastaan ​​(24). Kynsiöljyn todettiin toimivan myös Escherichia-kelan kliinisiä kantoja vastaan, spesifisiä bakteereja, jotka ovat erittäin vastustuskykyisiä useille antibiooteille (25). Espanjan Seafood Microbiology and Technology Sectionin tekemässä tutkimuksessa todettiin, että neilikan eteerinen öljy tappoi tehokkaasti Staphylococcus aureus -biofilmit (26) .

Lisäksi neilikkaöljy vaikuttaa Candida albicansia vastaan, mikä aiheuttaa suun sammas, urheilijan jalka ja emättimen hiiva-infektiot. Neilikkaöljyn eugenolilla voi olla antikandidaalinen vaikutus (27). Toyaman lääketieteellisen yliopiston tutkimuksessa todettiin, että asykloviirin yhdistelmä. Toyaman lääketieteellisen ja farmaseuttisen yliopiston tekemässä tutkimuksessa todettiin, että asykloviirin (viruslääke) ja neilikan yhdistelmä hiirissä voi hoitaa herpes simplex-virusinfektiota (28). Eteerinen öljyseos neilikkaöljyn kanssa voi merkittävästi heikentää influenssavirusta. Öljyseoksella käsitellyillä viruksilla oli minimaalinen virusproteiinien ilmentyminen. Tämä tarkoittaa, että neilikkaöljyllä voi olla kyky torjua tiettyjä infektioita aiheuttavia viruksia (29).

7. Voi toimia hyönteiskarkotteena

Kynsiöljy voi toimia hyönteiskarkotteena ja estää vektorin kautta tarttuvia sairauksia (loisen ihmisissä aiheuttamia) (30). Tutkimuksessa havaittiin, että neilikan eteerisen öljyn komponentit voivat olla hyödyllisiä kehon täiden karkotteiden tuotannossa (31). Kynsiöljy voi myös osoittaa hylkivää vaikutusta japanilaisia ​​termiittejä vastaan ​​(32).

Thaimaan Mahidol-yliopiston tekemässä tutkimuksessa todettiin, että neilikkaöljy voi torjua Leptotrombidium-chiggereitä , jotka ovat toukkalajeja. Öljy voi myös olla turvallisempi ja halvempi vaihtoehto synteettisille karkotteille, jotka voivat aiheuttaa sivuvaikutuksia (33). Kynsi eteerinen öljy osoitti myös karkotusta toista toukkilajia , Leptotrombidium delienseä (34). Myös neilikan eteeristä öljyä sisältävän formulaation todettiin olevan tehokas Aedes aegypti -hyttystä vastaan (35).

Kynsiöljyssä oleva eugenoli voi toimia myös lupaavana vaihtoehtona tavallisille hyönteismyrkkyille (36). Neilon bioaktiivisten kemikaalien eugenolin, eugenoliasetaatin ja beetakaryofylleenin havaittiin kykenevän torjumaan punaisia ​​tulimuurahaisia ​​(37).

8. Voi vähentää vatsakipua

Kynsiöljyssä olevan eugenolin on ehdotettu olevan hyödyllinen ruoansulatuskanavan vaivojen, kuten vatsakivun, hoidossa. Sitä käytetään myös yskän, liman ja rintakehän ruuhkautumisen hoitoon (38). Kynsiä voidaan käyttää vatsakivun vähentämiseen. Tämän väitteen tueksi on kuitenkin saatavilla vain vähän tietoja.

9. Toukokuu parantaa sydän- ja verisuoniterveyttä

Kynsiöljy voi auttaa parantamaan sydän- ja verisuoniterveyttä. Perinteisesti sen tiedetään parantavan verenkiertoa. Rotatutkimus osoitti, että eugenoli öljyssä laajensi aivovaltimoita. Tämä voi ihmisillä merkitä alentunutta aivohalvauksen riskiä (39). Rotilla eugenolihoito voi alentaa verenpainetasoja ja jopa hidastaa sykettä (40). Toisessa tutkimuksessa runsaasti fruktoosia sisältävillä rotilla, kun heille annettiin neilikan eteeristä öljyä, havaittiin paranemista rasvahapossa. Öljy voisi myös säätää rottien kolesterolitasoja. Tutkimus ehdottaa neilikkaöljyn mahdollisia kardioprotektiivisia ominaisuuksia (41).

Diabeettisilla rotilla kynsiöljy voi myös näyttää kardioprotektiivisia vaikutuksia. Tämä voi johtua öljyn antioksidanttiominaisuuksista (42). Toisessa tutkimuksessa todetaan, että eugenoli voisi olla terapeuttisesti käyttökelpoinen verenpainetta alentavana aineena (43).

10. Voi edistää hiusten kasvua

Eugenol is known to stimulate the hair roots. A formulation containing clove oil was found to condition hair and enhance its growth. It could repair the hair shaft (44). However, more studies in this line are needed to reach further conclusions.

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 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.
