CLOVES (Syzygium Aromaticum, active ingredients: Eugenol, Flavanoids, Kaempferol, Rhamnetin)  are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum. They are native to the Maluku Islands (or Moluccas) in Indonesia, and are commonly used as a spice. Cloves are commercially harvested primarily in Bangladesh, Indonesia, India, Madagascar, Zanzibar, Pakistan, Sri Lanka, and Tanzania. Cloves are available throughout the year.

Cloves are used in the cuisine of Asian, African, and the Near and Middle East countries, lending flavour to curries, marinades, as well as fruit such as apples, pears or rhubarb. Cloves may be used to give aromatic and flavour qualities to hot beverages, often combined with other ingredients such as lemon and sugar. They are a common element in spice blends such as pumpkin pie spice and speculoos spices.
