Herbs are various kinds of herbaceous plants whose fresh or dried parts are used to season foods, provide fragrances, supply natural dyes, or make industrial or pharmaceutical products.
Culinary herbs are ones which fresh or dried leaves are used in cooking.
Some of the common culinary herbs are basil, French tarragon, rosemary, and thyme. Culinary herbs are different from spices. Generally, culinary herbs are fresh or dried leaves while spices are seeds, roots, fruits, flowers, and bark. Culinary herbs usually have a mild flavor while spices tend to have a stronger, pungent flavor. However, the terms herb and spice are artificial categories.
