Or Mudcrab Chitin. Or Vampire Dust....
No, you would have to make a potion with those.
I think only hawk feathers will cure disease just from eating it. (unless you have the alchemy perk that reveals secondary and tertiary effects from eating ingredients) vampire dust has cure disease as a fourth effect and mudcrab chitin and charred skeever hide have it as a second effect.
Also, Hawk feathers weigh 0.1 each while a cure disease potion weighs 0.5 each so you can save some carry weight by just holding a few feathers instead of a few bottles of potion.
