Cloves

Like other spices, cloves are available throughout the year. They are renown for providing their uniquely warm, sweet and aromatic taste to ginger bread and pumpkin pie, but they can also make a wonderful addition to split pea and bean soups, baked beans and chili.

Cloves are the unopened pink flower buds of the evergreen clove tree. The buds are picked by hand when they are pink and dried until they turn brown in color. Cloves are about ½ inch long and ¼ inch in diameter and with their tapered stem, they resemble tiny nails. In fact, their English name is actually derived from the Latin word clavus, which means nail. Although cloves have a very hard exterior, their flesh features an oily compound that is essential to their nutritional and flavor profile.

 


Health Benefits

Clove contains significant amounts of an active component called eugenol, which has made it the subject of numerous health studies, including studies on the prevention of toxicity from environmental pollutants like carbon tetrachloride, digestive tract cancers, and joint inflammation. In the United States, eugenol extracts from clove have often been used in dentistry in conjunction with root canal therapy, temporary fillings, and general gum pain, since eugenol and other components of clove (including beta-caryophyllene) combine to make clove a mild anaesthetic as well as an anti-bacterial agent. For these beneficial effects, you’ll also find clove oil in some over-the-counter sore throat sprays and mouth washes.

Anti-Inflammatory Activity

Eugenol, the primary component of clove’s volatile oils, functions as an anti-inflammatory substance. In animal studies, the addition of clove extract to diets already high in anti-inflammatory components (like cod liver oil, with its high omega-3 fatty acid content) brings significant added benefits, and in some studies, further reduces inflammatory symptoms by another 15-30%. Clove also contains a variety of flavonoids, including kaempferol and rhamnetin, which also contribute to clove’s anti-inflammatory (and antioxidant) properties.

A Nutrient-Dense Spice

Like its fellow spices, clove's unique phytonutrient components are accompanied by an incredible variety of traditionally-recognized nutrients. Using our nutrient ranking system, we determined cloves to be an excellent source of manganese, a very good source of dietary fiber, vitamin C and omega-3 fatty acids and a good source of calcium and magnesium.

Description

Cloves are the unopened pink flower buds of the evergreen clove tree. The buds are picked by hand when they are pink and dried until they turn brown in color. Cloves are about ½ inch long and ¼ inch in diameter and with their tapered stem, they resemble tiny nails. In fact, their English name is actually derived from the Latin word clavus, which means nail.

Although cloves have a very hard exterior, their flesh features an oily compound that is essential to their nutritional and flavor profile. Cloves have a warm, sweet and aromatic taste that evokes the sultry tropical climates where they are grown.

The Latin name for cloves is Eugenia caryophyllus.

History

Cloves are native to the Moluccas, formerly known as the Spice Islands of Indonesia. They have been consumed in Asia for more than 2,000 years. Owing to their sweet and fragrant taste, Chinese courtiers dating back to 200 BC would keep them in their mouths in order to freshen their breath when addressing the emperor so as to not offend him. Arab traders brought cloves to Europe around the 4th century, although they did not come into widespread use until the Middle Ages when they became prized for their pungent flavor that served to mask the taste of poorly preserved foods. While for a long time, they were cultivated almost exclusively in Indonesia, today the leading clove-producing region is Zanzibar in Eastern Africa. In addition to these two regions, cloves are also grown commercially in the West Indies, Sri Lanka, Madagascar, India, Pemba and Brazil.
