Clove, or Syzygium aromaticum, originated in the Spice Islands. They were first found on Ternate, in the Maluku Islands (Moluccas) of eastern Indonesia. Trade of the plant began 2,500 years ago, and soon spread worldwide. The plant is a tall and thin evergreen and can reach up to 20 meters. Its flowers grow in bunches, and when they bloom, they look like red and white bells. After a slow drying process in the sun, they shrink until they look like tiny nails. (In the Basque language, the word for cloves, iltze-kanela literally means cinnamon nails — iltzatu nail).
Cloves have a highly aromatic and pungent taste and an intense, pleasant fragrance. The essential oil is obtained from the flower buds or leaves through steam distillation. Clove oil is mainly composed out of Eugenol (70-85%), an ingredient used to make prosthetics in dentistry. Clove also contain antioxidants that help strengthen the blood vessel walls.
Specialists in herbal medicine use clove oil for digestive disorders, insect bites, insect repellant, tooth pain, coughs, intestinal gas, nausea and vomiting.

It may be used added to hot water and inhaled or in a hot bath when used as an expectorant, to ease the coughing up of phlegm.

They are also as a spice, and added to confectionery, sauces, some soups, pork meat, sausage seasoning, on some types of cakes, mulled wine or tea. They give special flavor to rice.
