Alkahest

Alkahest is a theoretical substance believed to have the power to neutralize or reverse the effects of aging by removing or repairing accumulated cellular damage in the body. Inspired by the mythical universal solvent from alchemy, it suggests a potential way to rejuvenate tissues and restore youthful function. While the concept is intriguing, it remains speculative and has not been proven in humans. Researchers explore similar ideas through ways to cleanse or replace damaged cells, but Alkahest itself is more a concept or goal in aging research rather than an existing treatment.
