"They are," Harry confirmed. "But the White Elixir, which is the most powerful I've successfully made so far, is really only effective for physical injuries. It soothes aches, fixes bones and cuts, that sort of thing. And, just like the blood thinning potion, I've taken that plenty of times, too. If that was the solution, it would have made more of a dent in Riddle's little legacy on me by now. It seemed to work when I used it on you for Dolohov's Curse, but I was obviously wrong about that. That spell was genuinely powerful enough to be a fourth Unforgiveable. It literally attacks all body organs at once and degrades them at speed ... it practically ages them in seconds. Complex as hell ... and totally deadly. My White Elixir isn't anything like as potent enough to cure it."
