I'll have to double check when I get home from work (unless someone wants to check on their own before then) but I'm reasonably certain that the last major patch changed it to only remove detrimental effects, not put a buff up as well that had the same functionality as before.

I use it for the concussion from Toy Hammer from the first boss in Antitower and watch the buff and debuff status of the tank to make sure it hit and I've not seen it add a buff.
