ABSTRACT
Herbs are plants traditionally used for food, medicine, or perfume, whereas spices are substances used mainly for avoring, coloring, and preservation of food. Although it is difcult to differentiate between them, in general, herbs come from the leafy part of the plant (even though other parts of some plants are used as herbs), while spices are the parts of the plant other than the leafy part. According to the American Spice Trade Association, spices are dened as any dried plant product used primarily for seasoning purposes. Herbs have attracted a lot of scientic attention in recent decades because of the health benets they offer. The important properties are their biological activity for pharmacological use, antiaging and antioxidant properties, antimicrobial property, etc. The use of herbs has increased manyfold in pharmaceutical, cosmetic, and food industries owing to their aforementioned characteristics.
