It's really important to understand herbs do go bad over time, even if you store them in a dry, dark place. This is the same herb (gotu kola, if you must know): on the left is over a year old. On the right is a fresh order. Granted they're from two different sources, but I think time and deterioration is the main take away. If you're trying to work with symptoms or even wellness, open up the bags and make sure the color and scent of your herbs are good 🌿
