Not true about Draugr Fang. You don't use Ooze to craft the bow, so your argument that "they're poisonous because the ooze you craft them from is naturally poisonous" doesn't even follow. ANY arrow fired from Draugr Fang does poison damage, no Ooze involved.
The Gunk used in crafting the bow isn't used to make any other poison damage, and the limited amount used couldn't poison endless arrows even if it was, without the use of magic.
