Cloves are the aromatic flower buds of the *Syzygium aromaticum* tree.

This evergreen tree belongs to the Myrtaceae family. It can grow to a very tall height. The buds are the part of the plant that people harvest. They are used globally as a spice, a flavoring, or a fragrance. You might find the scent of cloves in consumer products like toothpaste, soaps, or cosmetics. Because different countries have different harvest seasons, cloves are available to buy throughout the entire year.

The life cycle of a clove bud involves a specific change in color. The buds begin with a pale hue. They then gradually turn green as they develop. Finally, they transition to a bright red color when they are ready for harvest.

The harvested clove consists of a long calyx. This calyx ends in four spreading sepals. It also contains four unopened petals that form a small central ball. The external texture of a dried clove is brownish, rough, and irregularly wrinkled. It feels dry and woody to the touch.

There are different types of cloves based on how they are processed. Mother cloves, or *anthophylli*, are the ripe fruits. These are ovoid, brown berries that contain a single seed. Blown cloves are expanded flowers. In these, both the corollae and the stamens have been detached. Finally, there are exhausted cloves, which are also called used cloves. These are cloves from which most or all of the oil has been removed through a process called distillation.

The intense flavor and aroma of cloves come from a chemical compound called eugenol.

This compound makes up 72% to 90% of the essential oil extracted from the spice. Because eugenol is so powerful, people typically only need a very small quantity of cloves in their cooking. Cloves are used in many different cuisines around the world. In Asian, African, and Mediterranean cooking, they flavor meats, curries, and marinades. They are also used with fruits like apples, pears, and rhubarb. In Mexican cuisine, they are known as *clavos de olor*. In Peru, they appear in dishes like *carapulcra* and *arroz con leche*.

Cloves have a history that stretches back thousands of years. They are native to the Maluku Islands in Indonesia. Archaeologists found cloves in a burned house in Terqa, Syria, dated to 1720 BC. This is the first evidence of cloves being used in the West before Roman times. In ancient China, cloves played a role in official etiquette. The book *Han Guan Yi* from around 200 BC states that ministers should suck cloves to sweeten their breath before speaking to the emperor. During the Song Dynasty, Chinese merchants imported cloves through various shipping offices.

Trade for cloves has shaped global history. The Austronesian peoples first traded them through a massive maritime network.

During the 17th century, the Dutch East India Company tried to create a monopoly. They wanted to be the only ones controlling the trade. However, unlike nutmeg, clove trees grew all over the Moluccas. This made it very difficult for the company to police the trade effectively. Today, Indonesia is the largest producer of cloves in the world. Other major producers include Madagascar, Tanzania, Sri Lanka, and Comoros.

Beyond the kitchen, cloves have many practical and medicinal uses. Clove essential oil is used as an anodyne, which is a substance used to relieve pain. It is often used in traditional medicine for dental emergencies, such as toothaches. Some studies suggest the oil may prevent the growth of *Enterococcus faecalis* bacteria during root canal treatments. The oil is also used in aromatherapy. In the past, people in Victorian England made fragrant pomanders by combining cloves with an orange.

This was a way to show warmth of feeling when given as a gift.

Cloves also connect to science and conservation. Clove essential oil can be used to inhibit the growth of mold on various foods. In the field of cultural heritage conservation, clove oil can be used to protect wood. Research has shown that clove oil can be more effective than boron-based wood preservatives. In Indonesia, cloves are even used in a type of cigarette called *kretek*. While they were smoked widely in Europe and the United States in the past, clove cigarettes are now classified as cigars in the United States due to flavoring bans.
