Health Benefits of Cloves: What You Should Know

Cloves are small, aromatic flower buds commonly used as a spice in cooking, baking and traditional food preparations.

They are known for their strong flavour and distinctive smell and contain natural plant compounds, including eugenol, that have attracted scientific interest.

When consumed in normal food quantities, cloves can be part of a balanced diet. However, while research has identified several potentially beneficial properties, cloves should not be regarded as a cure for diseases or a replacement for prescribed medical treatment.

1. Cloves contain antioxidant compounds

Cloves contain antioxidants that help protect cells from oxidative stress caused by unstable molecules known as free radicals.

A diet containing a variety of antioxidant-rich foods, including fruits, vegetables, nuts and spices, can contribute to overall health. However, eating cloves alone cannot prevent or treat chronic diseases.

2. May support digestion

Cloves have traditionally been used in different cultures to support digestion. Their aromatic compounds may have an effect on digestive processes, although evidence from human studies is still developing.

Adding small amounts of cloves to meals or drinks can provide flavour while contributing to overall dietary variety.

Anyone who experiences persistent stomach pain, vomiting, severe heartburn or other ongoing digestive symptoms should seek medical advice rather than relying on spices as treatment.

3. May contribute to oral health

Eugenol, one of the major compounds found in cloves, has antimicrobial and soothing properties that have attracted interest in dental research.

Clove preparations have traditionally been used for temporary relief of tooth discomfort. However, a toothache can be a sign of decay, infection or another dental problem.

Good oral hygiene remains essential. Brushing twice daily with fluoride toothpaste, cleaning between the teeth and having regular dental check-ups are more important for maintaining healthy
teeth and gums.

4. Contains anti-inflammatory compounds

Some compounds in cloves have demonstrated anti-inflammatory activity in laboratory and experimental research.

Inflammation is a normal part of the body’s response to injury or infection, but prolonged inflammation can be associated with various health conditions. Although the findings surrounding cloves are promising, more research involving humans is needed to determine how significant these effects are when cloves are consumed as food.

5. May support general wellbeing

Cloves provide small amounts of several nutrients and plant compounds. Using them to add flavour to meals can also help people enjoy a wider variety of foods.

For example, ground cloves can be added in small quantities to soups, stews, cereals, baked foods and selected beverages.

A balanced diet containing vegetables, fruits, whole grains, protein sources and healthy fats remains much more important than any individual spice.

6. What about blood sugar?

Researchers have investigated whether compounds found in cloves could influence blood-sugar regulation.

Some early studies have produced interesting findings, but this does not establish cloves as a treatment for diabetes. People living with diabetes should continue taking prescribed medication and following the advice of their healthcare provider.

Anyone experiencing symptoms of high or low blood sugar should seek appropriate medical care rather than attempting to manage the condition with cloves.

7. May have antimicrobial properties

Laboratory research has found that certain compounds in cloves can inhibit the growth of some microorganisms.

This has contributed to interest in cloves and their potential applications in food preservation and oral-care products. However, laboratory findings do not mean that eating cloves can cure bacterial, viral or fungal infections.

If you have an infection, appropriate
medical treatment should be sought.

How to use cloves

Cloves can easily be incorporated into meals in small amounts. They may be:

Added to soups and stews

Used as a seasoning for meat and vegetables

Added to some teas and warm drinks

Ground and incorporated into baked foods

Combined with other spices in homemade seasoning blends

Moderation is important because cloves have a very strong flavour and excessive consumption may cause irritation or stomach discomfort.

Is clove oil safe?

Clove oil is much more concentrated than whole or ground cloves and should be treated differently.

Undiluted clove oil can irritate the skin, gums and other tissues. It should not be swallowed in large amounts.

People considering using clove oil for a health problem should first speak with a qualified healthcare professional.

Who should be cautious?

People who take regular medication, have a bleeding disorder, are preparing for surgery, or have other medical conditions should speak with a healthcare professional before using concentrated clove preparations or supplements.

Pregnant or breastfeeding women should also seek professional advice before using cloves in medicinal quantities rather than normal food amounts.

The bottom line

Cloves are a flavourful spice containing compounds such as eugenol and antioxidants that have been studied for their potential health properties. They may contribute to a healthy diet when consumed in moderate amounts.

However, many of the stronger health claims surrounding cloves still require more research in humans. Cloves should complement a balanced lifestyle, not replace medical treatment.

If you have persistent pain, signs of infection, abnormal blood-sugar levels or another concerning symptom, consult a qualified healthcare professional.
