What is herbs
Herbs are vital part of human existence. They have been used since prehistoric times for medicinal, culinary, gardening, and recreational purposes. Some of the earliest books, such as the Bible, mention herbs. Our conception of modern medicine is based upon our understanding of how plants benefit humans. Furthermore, plants have been exchanged among peoples and between countries for centuries. In North America, Native American herbal medicines were sometimes traded with colonists.
