I don't think I'd want to be in a room with these very angry druids
... On the live realms at present druids cannot use consumables in forms -- the lack of useful things like health potions and healthstones is certainly an annoyance, but after playing a druid for a while you start getting used to the trend of shifting out of feral forms whenever you need to do anything important. However, on the beta realms Blizzard dangled a carrot: for a brief period of time, "certain consumables were flagged as usable in some forms, and that has since been reversed." Drysc claims this was a bug and a mistake
-- but even after his comments, countless druids insist that he is uninformed and that the change can't be a bug, pointing at recent changes to the text of Thistle Tea
(restores energy) and Rage Potions
(restores rage) to include druids under their class restrictions. And while I admire so many druids for believing so whole-heartedly in the power of their dreams, I wonder how much hope there is for a change after it's been confirmed as a bug.
