Herbs vs. Spices

This article was published originally on 8/22/2003

We often use the words herb and spice interchangeably. Herbs and spices are obtained from plants. (Salt is neither a spice nor an herb. It is actually a mineral.) Herbs and spices are used primarily for adding flavor and aroma to food. And both are best used fresh but can be saved by drying. While there are similarities, there also are subtle differences between herbs and spices.

Herbs are obtained from the leaves of herbaceous (non-woody) plants. They are used for savory purposes in cooking and some have medicinal value. Herbs often are used in larger amounts than spices. Herbs originated from temperate climates such as Italy, France, and England. Herb also is a word used to define any herbaceous plant that dies down at the end of the growing season and may not refer to its culinary value at all.

Spices are obtained from roots, flowers, fruits, seeds or bark. Spices are native to warm tropical climates and can be woody or herbaceous plants. Spices often are more potent and stronger flavored than herbs; as a result they typically are used in smaller amounts. Some spices are used not only to add taste, but also as a preservative.

Some plants are both herbs and spices. The leaves of Coriandrum sativum are the source of cilantro (herb) while coriander (spice) is from the plant's seeds. Dill is another example. The seeds are a spice while dill weed is an herb derived from the plant's stems and leaves.
