Nitrotan is discontinued! Alternatives?

Ok. I might be a little behind the curve here, but I just went to re-up my nitrotan supply and discovered that it has been…gulp…DISCONTINUED!! For the first time in many decades I am without nitrotan.

Anybody got a similar tannic acid topical to replace?

Anybody got a super-secret nitrotan stash?

You use it for wound care?

blisters, light road rash, chafe wounds…
