Mezereum vs. Psorinum on the Skin — A Homeopathic Comparison
Both remedies hold a strong affinity for the skin, but they differ markedly in their lesion morphology, secretions/odour, thermal modality, and the constitutional terrain they belong to. Below is a side-by-side.
1. Primary sphere: Skin, mucous membranes, periosteum, nerves (1,2) (Mezereum)| Skin, sebaceous glands, lymphatics, post-acute debility (3,4) (Psorinum)
2. General look: Eruptions with thick, hard, leathery, elevated, whitish-yellow crusts (“chalk-like”), often described as eczema/kerion-like; raw surfaces beneath (1,2,5) (Mezereum)| Skin looks dirty, dingy, unwashed even after bathing; coarse, greasy, oily; sallow/yellow tint (4,6) (Psorinum)
3. Key lesions: Vesicular → crusted; ulcers with shining, fiery-red areola; zona/shingles; eruptions over bony prominences (2,5) (Mezereum)| Papules, vesicles, pustules, boils, indolent ulcers, crusty eruptions, eczema behind ears, urticaria after exertion (4,6,7) (Psorinum)
Itching & sensations
Mezereum: Intolerable itching < warmth of bed, at night; itching changes place after scratching; biting, tingling, formication; the part becomes cold after scratching (1,2,5).
Psorinum: Itching cool open air; scratching → vesicles, rawness, bleeding crusts; “dreads to be washed” (3,6).
Discharges & odour
Mezereum: Thick yellow-white pus under tough crusts; sometimes offensive; excoriating ichor that spreads lesions (1,2,5).
Psorinum: Filthy/carrion-like, nauseating odour from oozing and from the body itself — “no amount of washing removes it”; fetid foot-sweat (3,4,6,7). This is a keynote differentiator.
Modalities
Mezereum: Warmth of bed, night, touch, cold air (neuralgia), damp weather, warm food, motion (1,2,5) (Worse)| Open air, wrapping head, dark room (5) (Better)
Psorinum: Cold air/drafts (general), warmth of bed (skin), washing, woolens, winter (3,4,6) (Worse)| Warmth (general), open air for itching, lying with head warm (4) (Better)
5. Constitutional/associated features
Mezereum: Strong link to suppressed eruptions (by Zinc/Mercury ointments) → inveterate catarrh or eye disease; neuralgias (face, teeth); periosteal/bone pain (long bones, caries); syphilitic and mercurial miasm (1,2,5).
Psorinum: Lack of reaction — well-chosen remedies fail to act; profound debility after acute disease; profuse, offensive night-sweats; extreme chilliness but wants head kept warm; “feels poor” even when well-off; history of suppressed itch (3,4,6).
6. Clinical differentiation (quick memory aid)
1. Thick, dry, leathery crusts over pus + neuralgia + bone pains → think Mezereum (1,2).
2. Dirty, oily, smelly skin + lack of reaction + offensive sweat + despair about finances → think Psorinum (3,4,6).

IGraphites, Mezereum & Tellurium: Skin Disease Comparison
1. Disease Variety
Graphites: Eczema (especially moist, fissured), impetigo, intertrigo, keloids, cracked skin, thickened cicatrices, nail disorders, blepharitis, otorrhoea[1]
Mezereum Eruptions with thick crusts (like lepra), herpes zoster, neuralgia with skin eruptions, eczema of scalp, ulcerations, condylomata[2]
Tellurium Ringworm (especially circular lesions), favus, barber’s itch, eczema behind ears, offensive otorrhoea, skin disorders with sharp shooting pains[3]
2. Discharge and Color
Graphites: Thin, watery, sticky, honey-like discharge; transparent, glutinous “honey” oozes from cracks; sometimes thick yellow[1]
Mezereum: Discharge under thick crusts is acrid, corrosive, excoriating; thick yellowish-white pus beneath crusts[2]
Tellurium: Discharge has a distinctive garlicky, fishy, or pungent odor; thin, sometimes bloody[3]
3. Modalities (Better/Worse)
Graphites: Cold air, drafts, during/after menses, warmth of bed[1] (Aggravation)| Open air, cool applications (Amelioration)
Mezereum: Warmth of bed, evening, night, touch, cold damp air[2] (Aggravation)| Open air, wrapping up head (Amelioration)
Tellurium: Rest, lying on affected side, evening, cold air[3] (Aggravation)| Motion, open air, perspiration (Amelioration)
4. Causation
Graphites: Suppressed eruptions, hormonal changes, splinters, obesity, scar tissue[1]
Mezereum: Mercury poisoning, suppressed eruptions, venereal disease history[2]
Tellurium: Ringworm infection, exposure to tellurium fumes, fungal infections[3]
5. Sensation
Graphites: Burning, itching, stinging; raw, sore feeling in cracks; sensation of splinter[1]
Mezereum: Intense itching, especially at night; burning; neuralgic pains[2]
Tellurium: Sharp, darting, shooting pains (keynote); itching; soreness[3]
6. Thermal Relation
Graphites: Chilly patient; worse warmth of bed; cold aggravates eruptions[1]
Mezereum: Chilly, yet worse from warmth of bed (like a hot-water-bottle patient)[2]
Tellurium: Cold patient; burning sensations with general coldness[3]
7. Appearance
Graphites: Cracks and fissures(especially in flexures, behind ears, nipples, fingertips); thick, hardened, leathery skin; keloidal scars; “honey” crusts[1]
Mezereum: Thick, whitish, leathery crusts resembling rupia; underlying skin raw, bleeding; elevated white scabs[2]
Tellurium: Ring-shaped, circular lesions** with raised edges; overlapping rings; well-defined borders[3]
8. Food Desires
Graphites: Aversion to salt, fish, sweets; craving for chicken, beer[1] |
Mezereum: Aversion to meat; craving for coffee, fat, wine[2]
Tellurium: Craving for apples, fried foods, ice cream; aversion to beverages[3]
9. Mental State
Graphites: Indecisive, hesitant, timid; weepy; “weeps at music”; apprehensive[1]
Mezereum: Hypochondriacal, despairing of recovery; religious melancholy; irritable[2]
Tellurium: Restless, anxious; aversion to company; fear of being alone[3]
Key Differentiating Highlights
Graphites = Honey discharge + fissures + indecision
Mezereum = Thick leathery crusts + intense night itching + despair
Tellurium = Ring-shaped lesions + garlicky discharge + sharp darting pains
