From the 17th to the early 19th centuries, cloves were shipped to Europe. Competition led to naval battles between the Portuguese, Spanish, Dutch, and English.

The great French navigator Poivre, after enormous difficulties, managed to steal the plant from the Moluccas and transport it to the islands of Bourbon (now Reunion) and Mauritius, of which he was governor.

This is how the clove plantations arose.

The clove tree Syzygium aromaticum is an evergreen species belonging to the Myrtaceae family , which reaches over 10 meters in height. The buds of the clove are hand-picked before they bloom - this is how the spice clove is obtained. When dried, they have a dark brown color, a strong pleasant aroma and a pungent, spicy taste.

The spice is a popular ingredient in Christmas cookies and other dishes. When dried, it resembles the shape of a clove flower, hence the plant's name.

The spice contains a record amount of aromatic oil, which reaches 20%.

The essential oil is rich in plant phenylpropanoids, with the main compound being eugenol. Other bioactive compounds may include thymol, carvacrol, and cinnamaldehyde. The color of clove essential oil can range from pale yellow to golden brown, and its aroma is strongly spicy, smoky, similar to the spice clove.

Helps relieve toothache pain

Perhaps one of the most popular and traditional uses of this oil is to relieve toothache or gum pain. Eugenol, which is one of the main chemical components of cloves, can act as a natural anesthetic when applied topically.
