What is the shelf life of bulk herbs? What is the best way to store them?
Shelf life varies from one herb to another. A powdered herb will lose its properties much faster than a whole or cut herb. Those with volatile oils like peppermint will lose their freshness much sooner than those without the oils. Roots have the longest shelf life as they are much denser than say flowers and leaves. Most dried herbs last from one to two years. The best way to store them is in a cool dark place preferably in a sealed glass container.
