No list of items yet, however I have been able to find these items in the ruins:
juniper
sasafras
snakeroot
Also, I gathered moth wings and was able to activate a collector's quest just by having the itmes. they went from my bag to a collection area in my quest journal. You can do the same with bones as well.
None of the items or seasonings i've found in the ruins have value, so now I'm trying to find out how to use them. hope that helps a little ^^~
