Beyond reminding us of autumn and winter holidays, cloves also have nutritional value. For example, cloves benefits include:
Cloves are indigenous to the Middle East and have long been used in Indian Ayurvedic medicine and Chinese medicine for their supposed properties and ability to treat headaches and indigestion. These little bulbs are considered to have warming, stimulating and cleansing effects, and they can be utilized in a variety of ways — such as in cooking, as an extract, in herbal tea or in essential oil form.
The small, round spice that we know of as clove is actually tiny flower buds grown on the evergreen tree with the species name Syzygium aromaticum.
Can you eat cloves? Yes, which is why in small amounts they are typically ground and added to dishes like fall-inspired baked goods — such as gingerbread cookies, mulled wine and marinades for meats.
According to Spruce Eats, “Clove flower buds are harvested in their immature state and then dried. Whole cloves are shaped like a small, reddish-brown spike, usually around 1 centimeter in length, with a bulbous top.”
Today, cloves are mostly grown in India and Madagascar. In addition to being used a warm and aromatic culinary spice, it’s also the source of clove oil, which is a concentrated essential oil that is high in volatile compounds and antioxidants.
Cloves are rich in antioxidants, especially the type called eugenol, which is a phenolic compound that can reduce oxidative stress. This compound is present in concentrations of 80%–90% in clove bud oil and at 82%–88% in clove leaf oil.
Other bioactive compounds isolated from clove extracts include flavonoids, thymol, benzene and methylene chloride.
Studies have found that with its ability to fight free radical damage, eugenol may especially help defend against the development of chronic diseases and may help promote healthy aging.
Cloves benefits include some of the following:
In addition to fighting inflammation and acting as an antioxidant, eugenol also acts as a natural germicide due to its antimicrobial properties. This makes it similar to raw garlic, another type of bulb that contains immune-boosting compounds, such as allicin, that fight bacteria growth.
Clove also contains other compounds that have similar effects — for example, cloves can help prevent proliferation of certain harmful microbes that may cause oral or gastrointestinal infections and diseases. Additionally, research has shown that clove buds have immunostimulatory activities that can help promote immune response mechanisms.
Clove extract and oil are even sometimes used in food preservation because they can help keep growth of bacteria, including listeria, Pseudomonas aeruginosa, Salmonella, Streptococcus and Staphylococcus, under control. These can contribute to food poisoning.
Clove is also popular around the world in dentistry since it fights formation of gum disease.
Clove, and especially clove oil, has long been used in dental care due to its natural analgesic and anti-inflammatory properties, as well as its antiseptic and antibacterial effects.
It can help dull aches, reduce swelling and provide relief from discomfort among people with toothaches, skin breakouts, headaches and sometimes other conditions. It can also help prevent plaque from forming on teeth, which may cause painful cavities.
Clove extract, which is rich in polyphenolic compounds that support metabolic health, has been shown in some studies to help adults maintain normal blood sugar (glucose) levels.
One pilot study demonstrated that clove extract lowered pre- and post-prandial blood glucose levels in both healthy and pre-diabetic volunteers. It’s believed that clove’s essential oils, which are rich in eugenol and acetyl eugenol, help positively modulate pathways involved in glucose homeostasis, which can lower the risk for type 2 diabetes.
Cloves contain compounds that have ben shown to protect against formation of stomach ulcers, such as by increasing production of gastric mucus that helps prevent erosion of the stomach lining. At least one study has even found that clove can have similar effects as several anti-ulcer medications.
In extract form, clove can also contribute to healthy liver function by decreasing inflammation and oxidative stress and potentially helping to prevent liver damage and scarring.
What are the health benefits of clove tea?
Clove tea, which is made by steeping the bulbs in hot water, has many of the same anti-inflammatory compounds that clove spice has. Consuming it regularly may help reduce sore throats, cold and cough symptoms, and potentially digestive issues.
While it hasn’t been proven to help with weight loss, some people also drink clove tea for this purpose — and because it can ease bloating and water retention.
When consumed in small amounts in food, clove is generally well-tolerated and safe for most people, assuming they don’t have an allergy to the spice. However, clove oil should be handled with more caution, especially if using it internally.
Clove oil should only be ingested in very small amounts, since it can trigger side effects if over-consumed.
What are the side effects of cloves? Consuming clove oil has the potential to cause indigestion and other digestive issues, burning sensations, and possibly liver damage.
When applied topically it can also cause skin rashes, burning and tingling, so use with caution.
Clove oil and extracts are not recommended for women who are pregnant or breastfeeding, due to a lack of research.
People who are taking medications to control diabetes, hypoglycemia or bleeding disorders should only use clove products under supervision from a doctor, since eugenol can affect blood clotting and blood sugar levels.
What does clove taste like? Due to the presence of eugenol, it has a pungent taste. You’ll like detect notes of sweetness, bitterness, astringency (drying the mouth) and also heat.
For culinary purposes, cloves can be used either whole (such as in marinades) or ground in spice form. Pick out the clove bulbs before serving recipes, since they have a woody texture and very strong taste that is usually off-putting when consumed whole.
If using bulbs to make ground cloves, use a spice grinder, mortar and pestle or a clean coffee grinder. Use one teaspoon of whole cloves in place of 3/4 teaspoon of ground cloves.
Clove uses include adding a warm and distinctive flavor to:
What are some cloves substitutes?
The best substitutes include other, similar warm spices like nutmeg, cinnamon and allspice. Together, these spices are used in many of the same recipes, and they are the ingredients in pumpkin pie blends.
Overall, cloves are described as being “more powerful” in terms of flavor than similar spices, so only use a very small amount to keep the flavor from being overwhelming.
How much clove is safe to consume?
To keep ground clove or clove buds fresh, store them in an air-tight container at room temperature. Whole buds will remain fresh longer than finely ground powder.
When used as a ground spice, cloves contains very little calories but provide antioxidants and some essential vitamins and minerals, especially manganese — which is important for bone building, managing inflammation and regulating blood sugar.
Because of its strong taste, it’s often used only in small amounts in cooking, but for even more powerful effects clove oil and clove extract can be consumed.
One teaspoon (2 grams) of ground cloves contains about:
