Herbs have a variety of uses including culinary, medicinal, or in some cases even spiritual usage. General usage differs between culinary herbs and medicinal herbs. In medicinal or spiritual use any of the parts of the plant might be considered “herbs”, including leaves, roots, flowers, seeds, resin, root bark, inner bark (cambium), berries and sometimes the pericarp or other portions of the plant.
The English word “herb” which means to eat. It also originates from the Latin word “herba,” meaning grass or fodder. An herb is ” a seed producing annual, biennial, or perennial that does not develop persistent woody tissue,” in other words, a plant without bark. This definition applies to all herbs because although some herbs have somewhat woody stems, none have actual bark.
