Pulsatilla and Sepia are both first-rank remedies in women's health, both cover menstrual and pelvic complaints, both produce yellow-green discharges, and both can present a tearful patient who says she is not herself. The distinction is not in the pathology — it is in how the patient meets you. Pulsatilla wants sympathy and warmth of contact but cool air; Sepia refuses sympathy, is indifferent to her own family, and wants warmth, hard exercise and to be left alone.
The classical sources also record something a practitioner should know before prescribing either: Boericke lists Pulsatilla as inimical to Sepia. This guide sets out the differential and what that relationship means in practice, grounded in Boericke's Materia Medica and Boger's Synoptic Key.
Pulsatilla vs Sepia at a glance
| Pulsatilla | Sepia | |
|---|---|---|
| Disposition | "Mild, gentle, yielding"; "mild, timid, emotional. Weepy" | "Angry, sensitive and irritable and miserable"; "sad irritability, alternating with indifference or sulkiness" |
| Toward loved ones | Clinging; "fears in evening to be alone, dark, ghost" | "Indifferent to those loved best. Averse to occupation, to family" |
| Sympathy | "Likes sympathy"; children "like fuss and caresses" | Averse "to sympathy; to company; yet dreads solitude" |
| Weeping | "Weeps easily"; "weeps when talking"; better "after a good cry" | "Weeps when telling symptoms" — without relief |
| Temperature | Worse warmth, warm room, warm bed; better cold open air | Worse "cold: air; north wind. Wet"; better warmth of bed, hot applications |
| Air | "The patient seeks the open air; always feels better there" | Better for warmth, though also better from cold bathing |
| Motion | Better gentle and continued motion; worse beginning motion and rest | Better "violent motion"; better "by exercise" |
| Thirst | "Thirstless, short of breath and chilly" | Better for cold drinks |
| Discharges | "Profuse, bland, thick, yellow-green discharges" | Leucorrhoea "yellow, greenish; with much itching" |
| Pelvis | Menses late, scanty, "changeable, intermittent" | "Bearing-down sensation as if everything would escape through vulva"; prolapse |
| Symptom pattern | "Changeful. Shifting symptoms"; "the weather-cock among remedies" | "Symptoms settle in back"; shoot upward |
The mental axis — clinging versus withdrawing
Pulsatilla comes toward you. Boericke is explicit that "the disposition and mental state are the chief guiding symptoms to the selection of Pulsatilla," and describes a "mild, gentle, yielding disposition. Sad, crying readily; weeps when talking; changeable, contradictory." The mental section reads like a portrait of dependence: "weeps easily. Timid, irresolute. Fears in evening to be alone, dark, ghost. Likes sympathy. Children like fuss and caresses. Easily discouraged." Boericke's summing-up is the most quoted line in the entry — "mentally, an April day" — and Boger's is "mild, timid, emotional. Weepy" with a patient who "craves sympathy" and finds relief "after a good cry."
Sepia moves away. Boericke's mental picture inverts every one of those features: "indifferent to those loved best. Averse to occupation, to family. Irritable; easily offended. Dreads to be alone. Very sad. Weeps when telling symptoms." The contradiction is the key: she does not want company, yet dreads solitude — Boger's phrasing is averse "to one's own; to sympathy; to company; yet dreads solitude," with "stifled affections" and a mood that alternates between "sad irritability" and "indifference or sulkiness."
At the bedside. Console the patient. Pulsatilla softens, weeps more freely and feels better for it. Sepia stiffens, or resents it, and the weeping brings no relief.
Temperature and air — the fastest general
Both patients are chilly, so chilliness proves nothing. What they want done about it differs completely.
Pulsatilla is worse from heat and wants air. Boericke's is one of the most reliable observations in the materia medica: "the patient seeks the open air; always feels better there, even though he is chilly." The aggravations are "from heat, rich fat food, after eating, towards evening, warm room," and Boger adds worse from "warmth: air. Room. Clothes. Bed" and from "getting feet wet," with amelioration from "cold; fresh, open air" and "uncovering."
Sepia is worse from cold and wants warmth. Boger's aggravation list opens with "cold: air; north wind. Wet. Snowy," and the ameliorations are "warmth" and, in Boericke, "warmth of bed, hot applications, drawing limbs up." Sepia does take cold drinks and cold bathing well, but the general direction is toward heat, not away from it.
Motion is the second general. Pulsatilla wants gentle, continued movement and is worse from rest and from starting to move. Sepia wants violent motion — Boger's word — and Boericke's "better, by exercise." The classical picture of the exhausted Sepia patient who nevertheless revives when dancing has this modality behind it.
The pelvic picture
This is where the two are most often confused, because both are pre-eminent female remedies with yellow-green discharges.
Sepia bears down. The keynote is unmistakable when present: "bearing-down sensation as if everything would escape through vulva," with the patient obliged to "cross limbs to prevent protrusion, or press against vulva," and frank "prolapse of uterus and vagina." Boericke frames the whole remedy around "stasis and thereby ptosis of viscera and weariness and misery," with "weakness, yellow complexion, bearing-down sensation." The pains have an "upward tendency," and Boger notes "violent stitches upward in the vagina."
Pulsatilla changes. Its menstrual keynote is variability rather than prolapse: menses "too late, scanty, thick, dark, clotted, changeable, intermittent," with "chilliness, nausea, downward pressure, painful, flow intermits," and a classical causation of "suppressed menses from wet feet." The discharge is "profuse, bland, thick, yellow-green" — copious but not biting — although Boericke also records an "acrid, burning, creamy" leucorrhoea, so the discharge alone should never carry the prescription.
Inimical — what it means for practice
Boericke's Sepia entry lists Pulsatilla among its inimical remedies (alongside Lachesis). In classical usage that is a warning against following one with the other: inimical remedies disturb each other's action rather than building on it, unlike complementary pairs such as Sepia with Natrum muriaticum or Phosphorus, which Boericke lists as its complements.
Practically, this matters when a case has been prescribed on the wrong side of the differential. If Pulsatilla was given on a picture that later resolves into Sepia, the classical instruction is to allow the first prescription to be spent and to re-take the case, rather than moving straight from one remedy to the other and reading the muddle that follows as a Sepia failure.
Repertorising the choice
- Mind; CONSOLATION; ameliorates — Pulsatilla
- Mind; CONSOLATION; aggravates — Sepia
- Mind; INDIFFERENCE; loved ones, to — Sepia's decisive rubric
- Mind; WEEPING; sympathy, from — Pulsatilla
- Generalities; AIR; open; ameliorates — Pulsatilla
- Generalities; WARM; room; aggravates — Pulsatilla
- Generalities; MOTION; violent; ameliorates — Sepia
- Female; PROLAPSE; uterus — Sepia
- Female; BEARING DOWN sensation — Sepia
- Generalities; SYMPTOMS; changeable, shifting — Pulsatilla
- Stomach; THIRSTLESS — Pulsatilla
Where a case shows the pelvic pathology of one and the disposition of the other, the disposition wins: both remedies are prescribed on their mental state in classical practice, and the case-taking discipline that keeps the patient's own words intact is what makes that state legible.
