The whole concept of some items having hidden properties is that these items are not equipable, and their properties are only 'hinted' at in the item description. Perhaps this is a good question for the devs....
If you just carry a charm with you.... does it have some effect? Does 'a glowing lightstone' give off a beneficial light just by having it in your pack?
Other items have more intricate descriptions that hint at their properties.
I'm fairly certain that's just flavor text for the most part. Not to say it isn't possible that there's a greater meaning, but certainly nothing that has been demonstrated to this point.
