Drying herbs is one of the best ways to ensure that the herbs are available all year round. If done properly, drying can help maintain flavor, color, oil content and the medicinal value of the herb. Herbs will inevitably lose some of their potency regardless of the method of drying used. However, preserving the herbs by drying ensures that you have herbs whenever you need them. Even though dried herbs are not as potent as fresh ones, it is possible to retain most of their potency.
