Metabolization appears in the depth-psychology corpus primarily as an analogical and procedural concept borrowed from biochemistry and transferred into the vocabulary of psychic transformation. The term designates the psyche's capacity to take in raw, undigested material—whether traumatic affect, archetypal energy, unconscious content, or somatic activation—and convert it into forms that can be integrated, utilized, or consciously borne. The corpus does not develop a single unified theory of psychic metabolization; rather, the concept surfaces across several distinct registers. In the somatic and trauma literature (Ogden), metabolization is grounded in the body's literal chemistry—oxygen, nutrients, cellular conversion—providing a physiological substrate for the metaphor. In the alchemical tradition as read by Edinger and Hillman, the alchemical operations of calcinatio, solutio, putrefactio, and sublimatio function as symbolic equivalents of metabolic stages: dissolution, digestion, purification, and reconstitution. In object-relations contexts (Kalsched's reading of Klein and Bion), the question of metabolization becomes one of whether the psyche can tolerate and process persecutory anxiety or must instead eject it via projective identification. The tension across these positions is whether metabolization is primarily a somatic, symbolic, or relational process—a question the corpus holds open rather than resolves.
Every cell in the body requires oxygen to convert nutrients into useable energy. When we inhale, we take in oxygen, without which we cannot move, metabolize, or transform food int
Ogden grounds metabolization in the literal biochemistry of cellular respiration, establishing the somatic substrate from which depth-psychological uses of the term derive their analogical force.

In order to escape being destroyed by its own death instinct, the child ejects its hatred outward onto the (bad) breast or penis (projective identification) where it can then 'locate' its otherwise unbearable anxiety as persecutory fears of attack
Kalsched's account of projective identification implicitly frames the failure of metabolization: when the psyche cannot internally process intolerable affect, it expels rather than digests it.

Calcinatio has a purging or purifying effect. The substance is purged of radical moisture... the energies of the archetypal psyche first appear in identification with the ego and express themselves as desires for ego-pleasure and ego-power.
Edinger presents calcinatio as the alchemical analog of psychic metabolization, whereby raw archetypal energies are purged of ego-contamination and rendered into their transpersonal essence.

Mortificatio is the most negative operation in alchemy. It has to do with darkness, defeat, torture, mutilation, death, and rotting. However, these dark images often lead over to highly positive ones—growth, resurrection, rebirth
Edinger frames mortificatio and putrefactio as a necessary metabolic decomposition of fixed psychic structures, through which new growth becomes possible.

The toad as prima materia is destroyed by its own greed or unbridled concupiscence... The alchemist then enters the picture and subjects the poison-laden carcass to the fire of the alchemical process.
The alchemical opus, as Edinger reads it, is a staged metabolization of prima materia: the psyche's raw, toxic contents are subjected to transformative fire and progressively refined.

Putrefaction or corruption takes place when a body becomes black. Then it stinks like dung and true solution follows. The elements are separated and destroyed. Many colors are afterwards developed, until the victory is obtained and everything is reunited.
Putrefactio is rendered as the most visceral phase of psychic metabolization, the dissolution phase in which separation of elements precedes their eventual reintegration.

The reduction of bodies into Calx by burning... Reduction of confusion to an essence, of moisture or a solid to 'a fine powder,' of misty remembrances to a poignant image, of a stubborn blockage to lightweight fantasy.
Hillman recasts calcination as an imaginative metabolization, the reduction of overdetermined psychic material to its essential, imaginal residue.

mercury can be extracted from certain compounds by heating. It vaporizes, sublimates, and reappears on the cooler portion of the vessel.
Edinger's account of sublimatio as extraction presents a further metabolic stage, the volatilization and reconstitution of psychic substance in a purified, elevated form.

Coagulatio is generally followed by other processes, most often by mortificatio and putrefactio. What has become fully concretized is now subject to transformation. It has become tribulation calling out for transcendence.
Edinger locates coagulatio within the metabolic sequence of the opus, noting that concretization is itself a stage to be dissolved and re-worked.

The coagulant sometimes appears in dreams as cheese – mother nature turning into culture and differentiated sense – awareness through fermentation and putrefaction.
Hillman invokes fermentation and putrefaction as cultural-imaginative analogs of metabolization, whereby raw nature is converted into differentiated symbolic awareness.
