Historical definition

Liquor essentialis is the humour that is converted into flesh and blood.

Meaning

Essentialis does not here mean a fragrant essential oil. The liquid is defined by what happens to it in the living body: it becomes flesh and blood. The entry therefore concerns the material of nourishment and bodily formation, rather than a general label for any highly purified extract.

Use in the book

Liquor salis is described through preservation from putrefaction, and Liquor Mercurii through healing power. Those qualifications distinguish different roles within the book’s accounts of the living body.
