I'm not sure if the herbs have the same efficiency if you just eat them instead of boiling, I sure cannot imagine myself eating a daisy as I go for a walk, but I could try a daisy tea at home.
This way we could also give another use for the different liquid containers (not sure how to write them in English, the wooden... glass? The wineskin?).
I cannot think much more right now related to this, but the community is good enough for some comments that, I'm sure, can enrich this idea 😬
