Spices are aromatic plant substances used to flavor, color, and preserve food. Derived from seeds, bark, roots, fruits, or flowers, common spices include cinnamon, turmeric, black pepper, cloves, and cumin. They have been valued for centuries not only for their culinary uses but also for their medicinal properties and role in ancient trade. Spices can enhance taste, aid digestion, and possess antioxidant, anti-inflammatory, or antimicrobial effects. Each spice brings a unique flavor profile—ranging from sweet and warm to hot and pungent—making them essential in cuisines around the world.
