Use proper storage techniques to maintain medicinal properties
Just like other foods, herbs should be protected from light, air, warm temperatures and moisture. Store your herbs in a dark container – preferably glass – in a cool, dark environment. Clear glasses are fine, but make sure they are not in light. Ideal storage temperature is between 18°C and 22°C.
Buy or harvest small amounts – only what you can use within a few months. The therapeutic quality of your herbs diminishes over time. Generally speaking, dried flowers and leaves will last for six months to one year if stored properly. Dried roots and bark last 1-2 years, or longer. Powdered herbs have the shortest shelf-life – less than six months. Bearing that in mind when purchasing and storing your herbs will help you get the most out of them.
