Yes they do, any item that is in the field, either in pots, chests, trees, posters, plants, drawers, cabinets etc...
TIP : I found this out the hard way, but if your inventory is filling up with certain components or medicines, you should sell or drop some and stay around 80 or 90, because if your at x99 with that item and you open a chest with that item in it it will tell you that your inventory is full and you cant take that item at that point and you will have to go back and find those chests in order for the achievement to pop...which is what I had to do and it sucked!!
