What does grimreaper mean in alchemy?

In alchemy, the term "grim reaper" is not a standard term; however, it can be interpreted metaphorically. It may symbolize the process of death and transformation, reflecting the alchemical principle that destruction is often necessary for rebirth and the creation of new substances. This aligns with the overarching themes of alchemy, which seeks to transmute base materials into higher forms, often represented by the symbolic death of the old to make way for the new.
