Because I've just gotten it, I thought I'd suggest this here as well.
Venture City (Part of the Fate More Kickstarter, see the appropriate thread) has a few interesting ways to clear stress. For example as part of "Special Effects". In Fate Core, there is an outcome called "Success with Style". It happens when you succeed with 3 or more shifts over your target. In Venture City, when that happens, you can activate one of your Superpowers special effects. Among those is "clear your physical stress track".
There's also a direct healing power as well. I would probably not want to use that in a Dresden Setting, but YMMV.
