When using herbs, is it important to know which part will have the active ingredients. To see the terminology of herbs, see our Terminology and Definitions page. Herbs are available in several different forms. You can also see our How to Use Bulk Herbs page for more information or our Products A-Z Page to see a list of all of our products.
