clove

Clove (Syzygium aromaticum) is a tropical tree in the family Myrtaceae native to the North Maluku archipelago of eastern Indonesia — historically the Spice Islands — whose dried flower buds have been among the most prized and traded spices in human history. The dried, nail-shaped buds contain 15–20% eugenol, a phenylpropanoid compound responsible for the characteristic pungent, warming flavor used in cuisines worldwide and in traditional Ayurvedic and Chinese medicine for pain relief, particularly dental pain. Clove trees grow 10–20 meters tall in humid tropical climates, producing pink flower buds that are hand-harvested just before opening and sun-dried to the brown, nail-like form known commercially. Control of the clove trade drove European colonial expansion into Southeast Asia in the 16th–18th centuries, with the Portuguese, Dutch, and British successively monopolizing production from the Maluku Islands. Today, Indonesia remains the world's largest producer, followed by Madagascar, Tanzania, and Sri Lanka. Clove is also a key ingredient in Indonesia's popular kretek cigarettes, consuming a large proportion of domestic production. Eugenol from clove is also used in perfumery and as a precursor in the synthesis of vanillin.
