'anti-psoric' originates from Greek and New Latin elements: the prefix 'anti-' (Greek, meaning 'against') combined with 'psōra' (Greek ψώρα, meaning 'itch').

'psōra' passed into Late/Neo-Latin as 'psora', which produced English derivatives such as 'psoric' (relating to psora). The compound 'anti-psoric' arose in English medical and homeopathic literature (19th century) to denote agents opposing psora.

Initially, the root 'psōra' denoted 'itch' or related skin afflictions; over time in medical/homeopathic usage it came to denote a broader 'psoric' miasm or constitutional tendency, and 'anti-psoric' came to mean 'against that miasm or tendency.'
