Reddit reviews Anatomy of the Psyche: Alchemical Symbolism in Psychotherapy (Reality of the Psyche Series)

Yes, to others ITT, and what you said OP, Psychology and Alchemy, in terms of clearest terms, but also arguably, Alchemical Studies. Jung is dense (!), but conversely also clear in moments.

If not finding the clarity in understanding sought in Jung himself some 'Post-Jungians (not strictly post in this case) work can be helpful, such as Edward F. Edingers work Anatomy of the Psyche: Alchemical Symbolism in Psychotherapy, and Maire-Louise Von Franz's Alchemy: An Introduction to the Symbolism and the Psychology and Alchemical Active Imagination.

Edinger's Anatomy of the Psyche may be a good read for you :)
