Boenninghausen's Method Step-by-Step Case Taking Guide

What Boenninghausen's Method Actually Asks of a Case Taker

Boenninghausen's approach, as set out in his writings on the repertory and the therapeutic pocket book, is a system for organising a case around general and characteristic symptoms rather than around a long list of particulars. The case taker's job is not to collect every detail the patient offers. It is to sort what is offered into categories that the repertory can use: the location of the complaint, the sensation, the modality, and the concomitant circumstances that accompany it.

That sorting is the practical core of the method. Boenninghausen grouped symptoms by their relationships, so that a remedy could be found through the concurrence of several well-chosen generals rather than through one striking keynote. A case taken in this style tends to be shorter and more structured than a free narrative, because the aim is to reach a small number of complete symptoms rather than a large number of fragments.

The case taker therefore works with a specific discipline: listen broadly, then narrow deliberately. Nothing in the method requires the patient to speak in technical language, and nothing requires the practitioner to accept a diagnosis as the starting point. The diagnosis may be recorded, but the repertorisation proceeds from the patient's own description of location, sensation, modality and concomitants.

Myth: You Must Record Every Symptom Before You Can Prescribe

A common assumption is that thoroughness means exhaustiveness, and that a case is not ready until every symptom has been written down. In Boenninghausen-style work the opposite is closer to the truth. A long, undifferentiated list creates noise: it makes almost every remedy match something, and it obscures the small set of symptoms that actually distinguish one remedy from another. The method favours a compact set of clearly defined symptoms over a sprawling inventory.

The reality is that case taking in this style is selective from the outset. The practitioner notes what the patient emphasises, what recurs, what is unusual, and what the patient links together spontaneously. Those are the raw materials. Material that is vague, borrowed from a previous consultation, or repeated only because it was prompted is generally set aside or marked as uncertain.

This does not mean cutting the interview short. It means the interview can be long while the resulting symptom list stays short. The skill lies in the transition between the two: hearing a full account and then reducing it to a working set without losing the patient's own wording.

• Keep the patient's own words for location, sensation and modality rather than translating them into textbook terms.
• Mark each symptom as confirmed, uncertain or hearsay, so later repertorisation can weight them differently.
• Record the diagnosis separately from the symptom list; it does not enter the repertory as a rubric.
• Note the sequence in which symptoms appeared, since order of appearance is itself information.

Step One: Establish the Location and the Extent of the Complaint

The first working step is to fix where the complaint is felt and how far it extends. Boenninghausen's schema treats location as a primary axis, and the repertory is arranged so that a symptom can be sought by body region and by the direction in which it spreads. A pain that begins in the right shoulder and travels down the arm is a different entry from a pain fixed in the shoulder joint, even if the patient describes both as the same ache.

Practically, this means asking the patient to point, to trace the path with a hand, and to say whether the sensation stays put or moves. Side is recorded where the patient can state it: left, right, or alternating. Where the patient cannot say, that uncertainty is written down rather than guessed, because a wrongly assigned side can send the repertorisation in the wrong direction.

Extent also covers whether the complaint is local or general. A headache confined to one temple, a headache that fills the whole head, and a headache that accompanies a general feeling of illness are three different records. The case taker writes each as it is described and does not merge them into a single entry.

Step Two: Capture Sensation, Modality and Concomitants in the Patient's Own Words

Once location is fixed, the case taker turns to sensation: what the complaint feels like. Patients rarely use repertory language, so the practitioner records the plain description and, if useful, notes a probable repertory equivalent alongside it. Burning, stitching, pressing, tearing, cramping and dull are common categories, but the patient's phrasing is what should survive into the notes.

Modality is the next axis and, in this method, one of the most heavily weighted. Modalities are the conditions that make the complaint better or worse: time of day, temperature, weather, motion, rest, food, position, pressure. Boenninghausen's repertory gives particular attention to aggravations and ameliorations that are consistent and clearly described, because these tend to be stable across a patient's history.

Concomitants are the circumstances that appear alongside the main complaint. They may seem unrelated: a headache that comes with nausea, a cough that comes with sweating, a joint pain that comes with irritability. In this method they are not incidental. They are the links that allow separate rubrics to be combined, and they are often what makes a small remedy picture recognisable.

Myth: The Method Ignores Mental and General Symptoms

A persistent claim is that Boenninghausen's method is purely physical and leaves out the mental and general state. That reading comes from the method's emphasis on location, sensation, modality and concomitants, and from its use of a compact repertory. It does not follow that mental symptoms are excluded. General symptoms, including temperament, disposition and reactions to surroundings, are recorded and can be used as rubrics in their own right.

What the method does resist is the habit of building a case almost entirely from mental symptoms. A striking mental picture may be vivid, but if it is the only well-defined thing in the case, the repertorisation rests on a narrow base. The method compensates by requiring that general and mental symptoms be corroborated by physical particulars, so that the prescription is supported from more than one direction.

The practical consequence for case taking is that mental and general symptoms are collected with the same discipline as physical ones. Vague statements such as 'anxious' are less useful than a specific description of when the anxiety appears, what triggers it, and what the patient does when it is present.

Step Three: Reduce the Case to a Working Set and Repertorise

The final procedural step is reduction. From the notes, the case taker selects a small number of complete symptoms, each with its location, sensation, modality and concomitant where these are known. Incomplete symptoms are kept aside. The working set is then converted into repertory rubrics, using the patient's description to choose the closest available heading.

Conversion requires judgement. A single patient phrase may map onto more than one rubric, and the case taker decides which mapping preserves the original meaning. Where a rubric is a poor fit, it is better to leave the symptom out of the repertorisation than to force it into a heading that changes what the patient said.

The rubrics are then combined, and remedies that appear across several of them are examined. Boenninghausen's emphasis on concurrence means that a remedy matching several axes is generally more interesting than one matching a single dramatic symptom. The result is a shortlist for study against the materia medica, not an automatic answer. Prescribing decisions belong with a qualified practitioner, and anyone using this material for study should treat it as a way of organising information rather than as a substitute for clinical training.
