I'm currently using the "Big Stinker" rune on my Gargantuan:
Big Stinker
The Gargantuan is surrounded by a poison cloud that deals 15% weapon damage as Poison per second to nearby enemies.
I was considering stacking this with Bad Medicine as a passive:
Bad Medicine
Whenever you deal Poison damage to an enemy, their damage is reduced by 20% for 3 seconds.
This seems like it could be useful to make my Gargantuan even more tank-ish. However, I don't know if the poison effect counts as poison damage for the purposes of the passive.
Can anyone confirm (via some repeatable test and/or official statement) that this works or doesn't?

While I was not able to find an official reply from Blizzard, the current opinion is yes: The poison cloud of the Big Stinker rune triggers Bad Medicine.
Several threads exist where people are stating that it works: [1][2][3][4][5][6][7][8][9].
