OCD and homeopathy: the individual behind the rituals
I compare six remedy pictures to illustrate homeopathic individualisation in the context of some OCD behavioural traits.
Obsessive-compulsive disorder, or OCD, involves unwanted thoughts, images or urges and the behaviours or mental rituals a person feels driven to perform in response. Checking and washing are familiar examples. Counting silently, seeking reassurance and trying to cancel one thought with another can be just as consuming. Relief may last only briefly before doubt returns. The NHS explanation of OCD symptoms describes this cycle.
Disturbing intrusive thoughts can be especially hard to speak about. An unwanted thought is not the same as a wish or intention. If OCD is taking up your time, disrupting daily life or leaving you distressed, speak to your GP; there is support available. I have included routes to help below.
My homeopathic approach begins with the individual experience of being unwell. The diagnosis matters, and so do the differences between people who share it: the particular fear, the quality of the repetition, the bodily tension and the circumstances in which things become easier or harder. Comparing remedy pictures makes this approach easier to understand.
What the repetition means to you
The useful question is often what has to happen before you can leave something alone. Does checking settle a fear of danger, or must the action produce a particular feeling of completion? Is a thought arriving uninvited, or are you deliberately repeating a phrase to quieten it? These can look similar from outside while feeling very different from within.
A homeopathic repertory is an index of symptoms arranged under headings called rubrics. Its language can be surprisingly precise. Desire for order describes one thing; cannot rest when things are not in the proper place adds the distress of being unable to leave the arrangement alone. Persistent thoughts draws attention to recurrence, while anxiety of conscience brings in moral unease. I use these distinctions to clarify an account, keeping the person’s own words beside the repertory wording.
A preference for tidiness, a conscientious nature or a spell of repetitive thinking does not by itself amount to OCD. In a consultation, I also ask about sleep, energy, physical symptoms, significant events and what has changed from your usual way of being. A characteristic pattern emerges from details that belong together.
The remedy pictures below come from homeopathic materia medica: the literature of provings, in which experiences are recorded after taking a preparation, and later clinical observations. Their value in individualisation lies in the particular combinations they describe. I compare those combinations with the whole person’s account, including the physical symptoms, rather than choosing from a single familiar trait.
Arsenicum and Carcinosinum: restless and unable to leave things alone
Arsenicum album: anxiety that keeps the body moving
In the Arsenicum picture, anxiety is restless. The person changes position, moves from place to place and finds it difficult to settle. The old materia medica describes anguish with tossing in bed, sensitivity to disturbance and irritation at conversation or noise. Mental distress has a bodily urgency; there is little ease in remaining still.
Conscience also enters the picture. One account describes anguish with a sense of not having done one’s duty. This gives more depth to the familiar description of Arsenicum as exacting or fastidious. When comparing this remedy, I look for the relationship between conscientious concern, sensitivity and physical restlessness. A neat room tells much less than that combination.
Carcinosinum: exacting standards and the pressure to finish
Carcinosinum brings another shade of restlessness. Its literature describes irritation over small mistakes made by others, difficulty concentrating and tension about completing something even when there is no urgency. The task can feel pressing before it has properly begun. Other accounts describe weariness alongside an inability to rest because of anxiety.
The pressure surrounding a task gives this picture its particular emphasis: what must be done, how it must be done and the difficulty leaving it unfinished. Tiredness and trouble gathering one’s thoughts belong alongside the urgency. Arsenicum’s restless anguish and Carcinosinum’s tension about completing tasks may overlap, but the distinction helps focus the conversation.
Sulphur and Natrum muriaticum: thoughts that keep returning
Sulphur: a crowded mind that loses hold of the present
Sulphur’s mental picture can be busy, distracting and difficult to switch off. One classical account describes disagreeable ideas crowding in alongside happier thoughts and melodies, much of the material coming from the past. The thoughts interfere with daily work and become troublesome in bed in the evening, preventing sleep. Another describes difficulty keeping attention on the task at hand.
This is a useful corrective to the familiar caricature of Sulphur as merely untidy or absent-minded. The mind can be intensely occupied while ordinary work becomes difficult. In a comparison involving repetitive thoughts, their crowding quality, their effect on concentration and their evening intrusion into sleep give the picture its shape.
Natrum muriaticum: the conversation that remains unfinished inside
Natrum muriaticum gives a more personal colouring to persistent thought. The materia medica describes returning to affronts both given and received. The mind revisits what someone said, or what one said oneself; the emotional impact of an exchange remains alive. Sadness appears elsewhere in the picture, sometimes with apprehension and palpitation.
For a person troubled by repetitive reviewing, the significance of the remembered exchange deserves attention. What still hurts? What remains unresolved? Sulphur’s account contains a crowd of ideas, memories and melodies; this Natrum muriaticum account concentrates on the sting of what has passed between people. Both can help sharpen an enquiry, without making every return to the past part of the same pattern.
Stramonium and Silicea: fear, disturbance and sensitivity
Stramonium: the need for light and company
Fear in the Stramonium picture can be immediate and overwhelming. A particularly useful account describes distress aggravated by darkness and being alone, with a wish for light and company. The surroundings matter: who is present, whether the room is dark and what changes the feeling of being threatened.
In an OCD consultation, the alarming content of an unwanted thought can draw all the attention. The Stramonium picture invites a closer description of the fear itself: its intensity, the effect of being alone and the difference made by another person’s presence. These circumstances give the comparison more substance than the subject of the thought alone.
Silicea: easily startled, with attention hard to sustain
Silicea’s picture includes a finely felt sensitivity to disturbance. Noise brings anxiety; small things cause a start. Restlessness and fidgeting accompany difficulty fixing the attention. The experience is both mental and physical: it is hard to concentrate, and the body reacts readily to what interrupts it.
Counting appears among Silicea’s repertory entries. To understand its place in someone’s account, I return to what the repetition feels like and what interrupts it. Sensitivity, concentration and the wider physical picture then help complete the comparison. Alongside Carcinosinum’s pressure to finish a task, Silicea draws attention to how readily a sound or interruption unsettles the person trying to do it.
The substances behind the names
These remedies also begin in very different materials. Arsenicum album is prepared from arsenic trioxide; Sulphur from the yellow element; Natrum muriaticum from common salt; and Silicea from silica. Stramonium comes from thorn apple, a plant with trumpet-shaped flowers and spiny seed capsules. Carcinosinum belongs to the nosodes, preparations originating in diseased tissue. Its name is not a diagnosis of the person for whom it is considered.
Natural history gives homeopathic study another dimension. A substance’s place in the world can make a remedy memorable, while its provings and symptom literature bring the portrait into human experience. In practice, I return to the person in front of me; it is their account that gives these comparisons meaning.
Getting support for OCD
You do not have to make sense of this alone. NHS treatment for OCD includes cognitive behavioural therapy with exposure and response prevention, usually shortened to CBT with ERP, and medication such as SSRIs where appropriate. ERP involves supported work with feared thoughts or situations while reducing the compulsive response. Any changes to prescribed medication should be discussed with the prescriber.
A GP can help you find appropriate care. In England, adults can also self-refer to NHS talking therapies. The BABCP therapist finder offers another route to an accredited CBT therapist; ask about experience with OCD and ERP. OCD-UK provides information and support for people affected by OCD and their families.
Homeopathic consultations can sit alongside this care. If you would like to discuss my approach, I offer consultations in Frome and online across the UK. My aim in taking a case is to understand how the difficulty belongs within your wider experience: what holds your attention, what unsettles you, and the details that make your account recognisably your own.
