What is in one teaspoon of allspice?

One teaspoon of allspice typically contains about 6 calories, 1.5 grams of carbohydrates, and negligible amounts of protein and fat. It is rich in essential oils, particularly eugenol, which gives it a warm, aromatic flavor reminiscent of a blend of cinnamon, nutmeg, and cloves. Allspice also contains small amounts of vitamins and minerals, such as vitamin A, vitamin C, and potassium.
