What is the best way to keep dried herbs fresh and potent after purchase?
Light and heat contribute the most to diminishing the potency of dried herbs. It is best to store the herbs in a glass container at room temperature (below 80° F) in a dark place. Wide-mouth mason canning jars are the best containers to use. Do not store medicinal dried herbs in the refrigerator or freezer. Condensation will form on the herbs and cause mold to develop.
