Heracles rescued Deianeira from rape by the centaur Nessus, using an arrow tipped with the poisonous blood of the hydra. Before his death, Nessus gave Deianeira a love charm composed of his own blood tainted with hydra blood.
Edinger deploys the Hydra's blood as the alchemical calcinatio agent par excellence, demonstrating that the creature's poison persists beyond its defeat to generate an inextinguishable, transformative torment.
Edinger, Edward F., Anatomy of the Psyche: Alchemical Symbolism in Psychotherapy, 1985thesis
These arrows were dipped in the blood of the Hydra which the hero had killed and whom we met a few pages ago; and they were deadly poison… He could not die, for he was immortal; but he could not live, because the Hydra's poison had no antidote.
Greene reads the Hydra's indelible poison as the mythological image of a wound that cannot be healed, linking it to Cheiron's immortal suffering and the irreversible consequences of heroic conquest.
The index references confirm that Greene treats the Hydra as a sustained symbolic node across her astrological-mythological analysis, associated with Scorpionic themes of fate, poison, and heroic ordeal.
Neumann lists the Hydra alongside figures of heroic and ethical confrontation, situating it as an archetypal obstacle emblematic of the ego's struggle with the forces of the unconscious.

My solution to this hydra-like dilemma takes the form of gestating two more books.
Levine employs the Hydra as a casual metaphor for the self-multiplying nature of unresolved intellectual problems, using the mythic image rhetorically rather than analytically.

the parts of the body most capable of detaching and proliferating-like the hydra's tentacles, which play the role of the germ-are not the buds' birth-place.
Simondon references the hydra as a biological model of undifferentiated proliferative capacity within his theory of individuation, treating it as a scientific rather than mythological example.
