Hmmm. Well, it goes without saying that I'm not a doctor of vampires or of anything else, but as with most problems, I would imagine that any remedy would need to follow from knowing what's causing the malady to begin with.
You mention lethargy and lacking energy. Have his inherent powers been diminished as well? There's a subset of vampires that are severely weakened by the sun rather than finding exposure to it fatal. There are also certain plants that can have negative effects on vampires — garlic is the most commonly-known one, of course, but wild rose can be incapacitating and hawthorn can cause injury. Has he done any woodworking or gardening lately? A hawthorn splinter or an errant rose thorn might be causing problems in a way that could otherwise be easily overlooked.
As far as restoratives go, obviously there the most universal option is blood. However, barring that, napping in the soil of their homeland is also effective. Since you mention topical treatments, I would assume that a mud mask spa treatment comprised of the soil of their homeland would work equally well. It's the connection to their place of origin that controls.
