A potion for prolonged life? Germes’ recipe, a secret handwritten note from an 18th-century Swedish physician

The analysis of the transcribed note made it possible to narrow down its creation to 1770-1820. It tells the story of Germes, whose secret elixir recipe was found in his jacket after he fatally fell off his horse at the age of 104, with his family members also living exceptionally long, which all accredits to the panacea described. The note contains accurate descriptions of its preparation and methods of administration, and Germes' elixir can be used in the treatment of a variety of medical disorders. Several similar recipes for elixirs for longevity were identified in the literature, with a contemporary remedy called "Swedish Bitters" being nearly identical in terms of ingredient composition. The origins of "Swedish Bitters" were traced back to the late seventeenth century or early eighteenth century, where it rapidly gained popularity in the European market, particularly in Germany. This may accredit the handwritten note's creation, modification, and embellishment through retelling.
