The main difference between an herb and a spice is the part of the plant that is used. Herbs come from the leafy part of the plant, while spices come from other parts like the seeds, bark, roots, or fruits. Herbs are usually milder in flavor, while spices tend to be stronger and more aromatic.
A spice is any substance that is used to alter the flavor of food, which includes such things as salt, which is a mineral and not an herb, or cinnamon, which is derived from tree bark and thus is also not an herb. The term herb really applies only to a leaf that has some flavor that we value, such as basil or oregano. Many spices do not derive from leaves.
