Within the depth-psychological corpus, vinegar occupies a precise and philosophically charged position inside alchemical hermeneutics. It is not treated as a household substance but as a highly condensed symbol of the aqua mercurialis — the corrosive, transformative water at the heart of the opus alchymicum. Jung draws on the Turba philosophorum and allied texts to establish vinegar as synonymous with the 'red spirit,' the sharpest solvent capable of reducing gold to pure spirit and thereby releasing the world soul. This identification places vinegar within the larger symbolic cluster of the prima materia: it appears in alchemical lexicons alongside urine, sea-water, dragon, serpent, and quicksilver as one of the thousand names for the one transformative substance. Von Franz extends this reading through the Aurora Consurgens, where 'pure water' disclosed in prayer is simultaneously 'pure vinegar' — an oxymoron that encodes the paradox of a substance that both destroys and regenerates. Hillman, reading Artephius, treats antimonial vinegar as the 'middle substance' effecting whitening through a souring — the depressive, Saturnine contraction that paradoxically opens psychic reality. The unifying thread is corrosive transformation: vinegar dissolves in order to purify, and its acidity is the very vehicle of psychological and spiritual transmutation.
"She is the sharpest vinegar, which causes gold to become pure spirit." "Vinegar" is synonymous with "water," as the text shows, and also with the "red spirit."
Jung cites the Turba to establish vinegar as the supreme corrosive agent of transformation — dissolving gold into spirit — and identifies it as interchangeable with the alchemical aqua and the 'red spirit,' linking it directly to the world soul.

"it is the sharpest vinegar, which decomposes everything, or a poison. But this poison is, as it were, birth and life, because it is a soul extracted from many things."
Von Franz reads the alchemical water-as-vinegar as a paradoxical substance whose corrosive destruction is simultaneously the vehicle of soul-extraction and regeneration, embodying the fundamental law that corruption generates new life.

he would show me the pure water, which I know to be pure vinegar.
Von Franz presents the Aurora Consurgens' identification of pure water with pure vinegar as a central mystical-alchemical paradox, in which the sought divine solvent is simultaneously the most corrosive acid.

"without antimonial vinegar no metal can be whitened." ... the souring of depression as well as puerile sulfur ... as long as the experiential mode produces a vivid sense of psychic reality, Whether vinegar, sulfur, or the processes
Hillman psychologizes the alchemical vinegar by equating its whitening function with the 'souring' of depressive experience, positioning it as one of several 'middle substances' that produce the albedo through a lived sense of psychic reality.

the blessed Water, the Water of the Wise, the venomous Water, the most sharp Vinegar, the Mineral Water, the Water of Celestial grace... For this alone perfects both stones, the White and the Red
Abraham's dictionary entry establishes vinegar as one canonical alias within the alchemical synonymy of Mercurius-as-prima-materia, uniquely capable of perfecting both the white and red stones.

they also call the simple water poison, quicksilver argentum vivum, cambar, aqua permanens, gum, vinegar, urine, sea-water, dragon, and serpent.
Jung catalogues vinegar as one item in the vast synonymy of the prima materia's aqueous form, demonstrating its membership in the symbolic cluster that defines the mercurial substance of the opus.

Edinger interprets the Shulamite's purgation by vinegar as part of the nigredo-coagulatio complex, where corrosive suffering is the instrument of psychic fixation and mortification.
