Give an example of a plant that is used as both herb and spice?

A great example of a plant used as both herb and spice is basil.

* As an herb: Basil leaves are used fresh in many dishes, especially Italian cuisine. They add a fragrant, slightly peppery flavor to sauces, salads, and pesto.

* As a spice: Dried basil leaves are often ground into a powder and used as a spice in soups, stews, and other dishes. It adds a more concentrated and earthy flavor than fresh basil.

So, basil can be enjoyed in both its fresh and dried forms, making it versatile for both culinary and medicinal purposes.
