Spices are fragrant, aromatic plants that consist of flower buds, bark, seeds, leaves and many other parts of a plant used to enhance the flavor or taste of food.
See the difference? Of course you do. That was easy.
Now for the rest of the story!
The differences may be very subtle, but the distinction is still valid.
First, here are some of the similarities between the two. The terms "spice" and "herb" have both been used to describe parts of plants (possibly dried) that are used to augment the flavor or taste of food, preserve foods and cure illnesses. In the culinary world, the terms are used almost interchangeably. Spices and herbs have been, and continue to be, common in most cultures around the world, both to flavor foods and for medicinal purposes.
The Herb Society of America says an herb is "any plant that may be used for pleasure, fragrance, or physic", while according to the American Spice Trade Association, spices are "any dried plant product used primarily for seasoning purposes."
But, what's the difference you ask. With the passage of time; the definitions for spices and herbs have changed. Once herbs were considered primarily as a medicinal while spice referred to rare and expensive food preparations. Today, their definitions are more diverse.
When cooking, the important difference between herbs and spice is how to use them and what part of the plant is used. Herbs come from the green parts of a plant such as the stem and leave and are used in generally larger portions, while most spices come from the root, seeds, bark or flowers of a plant and are commonly stronger tasting and are used in much smaller amounts.
Some plants can be both an herb and a spice. Dill for instance; using the stalk in soups and stews is an example of an herb while the use of the seed in most commonly considered a spice. Cilantro too provides both herb and spice. The fresh or dried leaves and called cilantro or Chinese parsley but, the whole or ground seed is called coriander spice.
Another important characteristic when distinguishing herb from spice is in knowing where the plant species originates. Spices tend to come from plants grown in tropical climates. Herbs, on the other hand are easily grown and found in many climates.
Rodale's Ultimate Encyclopedia of Organic Gardening (Rodale Books, 2009) describes some rules of thumb for telling spices and herbs apart:
Spices can be in the form of seeds, roots, bark, leaves, or vegetable matter placed in foods in small amounts in order to flavor, color, or to prevent the growth of bacteria.
Many spices are also used in medicine, religion, perfumes, beauty products, and for eating as well. One example is turmeric being used to preserve things, another is licorice which is used for medicinal purposes, and garlic as a vegetable. These are referred to by different terms in some instances. When used in the kitchen, spices are different from herbs.
Generally, herbs are leafy, green parts of plants and valued for flavor, scent, or other qualities. Like spices, Herbs are used in cooking, as medicines, and for spiritual purposes.
Some herbs, like basil and oregano, may be fresh and are usually chopped into small pieces.
Culinary use of the term "herb" typically distinguishes between herbs, from the leafy green parts of a plant, and spices, from other parts of the plant, including seeds, berries, bark, root, fruit, and even occasionally dried leaves or roots.
Well, anyway you slice it; herbs and spice are quite remarkable. For thousands of years, mankind has used herbs and spice not only as flavoring, but for their medicinal and healing qualities. Many of the compounds found in these plants may even prevent cancer, heart disease and diabetes.
Cooks and chefs everywhere will agree that herbs and spices lend flavor, texture, complexity and aroma and are indispensible.
