We often use the words herb and spice interchangeably, as they are both obtained from plants. Herbs are obtained from the leaves of herbaceous (non-woody) plants. They are used for savory purposes in cooking and some have medicinal value. Spices are obtained from roots, flowers, fruits, seeds or bark. Spices often are more potent and stronger flavored than herbs; as a result they typically are used in smaller amounts. To learn more about herbs and spices, click here and click the video link above.
