Calculus and salt as coagulator

Meaning

Calcul is the bodily stone in the author’s explanation of disease, not an act of calculation. Salt is called its unique coagulator, l’unique coagulateur, and the proposed answer is a salt endowed with a contrary dissolving effect. The apparent salt-against-salt paradox is resolved locally by differing faculties: the remedy is claimed for particular things with a specifically effective power, not for any salt whatever. The uniqueness claim belongs to the historical pathology and should not be converted into modern causation or treatment advice. This distinction also explains why a single English headword “salt” cannot carry every bodily effect without qualification.
