Eupion’s essence is mechanical sag with acridity: a lax, tired pelvic floor and uterine supports, a womb that drags down on standing and walking, a small of back that feels broken, and mucosae that sting and excoriate with acrid discharges. The second pillar is the mamma: nodular, tender breasts with burning, knife-like pains, intolerant of jar, worst before menses, better by cold applications and rest. The third is the dry, fissured skin analogue — especially behind the ears in children and at delicate margins (nipples, vulva, anus) — pruritic and made worse by warmth and washing, soothed by cool ablutions and unguents. These three circulate through her day: housework and stairs reawaken backache and bearing-down; warmth of kitchen and bed inflames itching; an embrace or a jolt lights stabbing in lumpy breasts; dread of coitus arises from soreness rather than frigidity. When she lies down, binds the pelvis, and cools the hot places, she is at once more herself — this immediate mechanical and thermal responsiveness is the practical test of Eupion [Hering], [Clarke], [Boericke].

The kingdom signature — a defatting, drying hydrocarbon — appears clinically as mucosal acridity and skin fissures; its “lightness” reads as ligamentous laxity rather than spasm. Miasmatically Psoric–Sycotic, it tends to functional sag, cystic/nodular gland change and chronic itchy catarrh; it is not a disorganiser like Kreosotum or a destructive “burning-corrosive” like Euphorbium. Thermal state leans warm-worse: heat of room/bed increases pruritus and congestion; coolness (not chill) is the friend. Pace is subacute–chronic, often postpartum or post-miscarriage, in house-bound exertion. Core polarities: bearing-down vs support, acrid excoriation vs cool ablution, jar-agg. vs rest, pre-menstrual congestion vs relief when flow is free. Micro-comparisons: Sepia also bears down, but she revives with exercise and has a distinct mental estrangement; Eupion seeks rest and mechanical support and is governed by acridity and breast nodularity. Kreosotum excoriates violently with fetid, often bloody discharges and caries-like destruction; Eupion is milder structurally but intensely pruritic. Conium/Phytolacca rule when mammary stoniness and radiating pains dominate; Eupion’s breast pains are burning and jar-provoked, with pre-menstrual timing and cool-amel. Petroleum/Graphites own the fissure-eczema, yet without the female pelvic triad they will disappoint. Thus the Eupion triad guides: (1) Uterine sag with broken-back weakness (better pressure/lying), (2) acrid, burning leucorrhœa/pruritus (worse heat), (3) nodular mastodynia (worse jar, better cold). When this triad repeats — and especially when retro-auricular cracks seal the skin analogue — Eupion earns the prescription.

Clinically, low–mid potencies (3x–6x/6C) act neatly in chronic pruritic leucorrhœa and postpartum sag with daily repetition; 30C–200C serve when the triad is crystalline and breast pains are prominent, dosing around the pre-menstrual window; LM/Q scales help in long-standing fibro-cystic breasts or habitual pelvic laxity alongside binders and pelvic floor work [Boericke], [Dewey], [Vithoulkas]. Repeat by need: when standing/housework brings back the “broken back” and burning flux, dose and rest; space as mechanical tolerance returns. Sequence often runs: Bellis-p. or Arnica (strain/trauma) → Eupion (acrid/pruritic sag + mastodynia) → Sepia or Helonias (constitutional tone). Management should mirror modalities: cool the hot places, support the sagging, avoid jar (use steps mindfully), loosen bands, and simplify diet.
