Nicholas Flamel's Cauldron

Origin
Nicholas Flamel was a 14th century scribe and manuscript seller who reputedly discovered the Philosopher’s Stone and became immortal. He lived, contributed to and died in Paris, although some speculate he survived and continued his work for a long time.

Effects
Developed artifact properties as a byproduct of its use in many of Flamel's alchemical experiments. Any substance brewed within the Cauldron will develop purifying qualities. Ingestion of said substances will impart longevity and enhanced regenerative abilities, while other substances mixed with them under high temperature will be broken down and reconstituted into something else, gold being the predominant outcome.

The ingested substances would eventually wear off, heightening the users sensitivity to illness and injury. While the physiological impact is not in-of-itself life threatening, it will drive the user into bouts of depression and possible suicide due to their forgetting about discomfort, even if the effects only last a relatively short time. Excessive use of the Cauldron, particularly out of pure greed, will result in negative outcomes. Ingesting brewed substances may instead deteriorate the body even if previous batches made the same way worked, and broken down substances will instead reconstituted into volatile, lava-like flows that will eliminate anything they touch.
