I don't know much about alchemy, but I've heard elemental aether will cure any ailment if you can incorporate it into your medicine. The problem is, it's mostly found beyond Earth and can only rarely be found on the planet's surface. Supposedly you can distill it from other materials.
Thank you, I will research this.
Sadly, the person I was attempting to help has died of Cancer; may he rest in peace.
But thank you very much for the clue here, another puzzle piece to the mystery.
