Cloves are the flower buds of the clove tree, an evergreen also known as Syzygium aromaticum. Found in both whole and ground forms. Cloves are best known as a sweet and aromatic spice in baked goods and in Indian cuisine. Even in small amounts, they are a good source of manganese. Animal studies have found that the compounds in cloves may support liver health and help stabilize blood sugar levels. However, for medicinal purposes, cloves are used in larger amounts, which can cause undesirable side effects. You should consult a medical professional before using cloves in large doses.
