I have a question for Susun.
I bought a pound of stinging nettle and comfrey. What is the shelf life for these items stored in the plastic bag they came in. Do you recommend vacuum sealing them in a jar? I also, have dried chickweed. Can I do a tea with it or vinegar?
Once the bag is open, it would be best to simply put them in a brown paper bag, kept away from temperature fluctuations, light and heat. Dark and cool is best - back of cupboard, etc. Hard to say exactly how long they would last as for ones purchased, most likely, you will not know how old they were when packaged. I would just periodically check them, making sure that the smell is not off. Remember that a herb dried should be the same as what they looked like alive, so red clover should be pink, not dark brown and so forth.
I have certainly used ones that were stored for over a year and still were good.
Dried chickweed would be good for teas and infusions, saving fresh plant material for vinegars and tinctures, if possible.
