Spells that get rid of Nauseated state.

[FunkBGR]

Funnily enough -

Heroe's Feast does it, although lamely. Nausea is one of those effects that my players have come to hate, and have scoured for ways past it. I'll let you know if they come up with more besides the Necklace of Adaption (which I think we house ruled that it does)

 

[blargney the second]

Mark of Purity (Dragonmarked p. 142) is a feat that provides immunity to nausea and sickening, and they can remove those conditions from someone else as a standard action at will. Mind you, it's only available to dragonmarked paladins and monks.
