I pulled out my PDR for Herbal Medicines and looked up what they listed for anti-inflammatory.
Abscess Root
Barley
California PepperTree
German Chamomile
Jack-in-the-Pulpit
Jacob's ladder
Kudzu
Quince
Sage
Strawberry
I have no personal experience with any of these in the context of the OP, but did find it interesting that the section on "Anti-flatulents" was over twice as long.
