Even in the debate of Alchemy and Paracelsus, I don't think that was alchemy proper. My current working hypothesis is that the stone is simply a conduit artifact, combined with the life and death powers of the bowls. Now the bowls, on their own, probably work like the Fountain of Youth from the fourth PotC movie. One person dies and another takes rtheir life. But with the stone, the power can stockpile. Say fifty people die and one person gets al of their years. The wood, I'm assuming, has some sort of resonant property that releases the energy from the stone.

But that's just a guess.
