In short: Headache descriptions in classical homeopathy offer examples of location and modality rubrics: throbbing, motion, pressure, timing and reported accompanying symptoms. This is a historical source-comparison exercise, not a guide to treating headache or heat illness with remedies. A rubric match cannot exclude a serious cause or establish clinical benefit.
Kent’s Head chapter lets students compare a broad pain rubric with more specific locations and modalities. This article studies the recorded Belladonna, Bryonia, Gelsemium, Nux vomica and Natrum muriaticum pictures. It continues the series begun with acute fever and sore throat.
This article is for professional reference study and supervised student learning, not self-treatment. Medical assessment, indicated care and follow-up take priority over repertory work. Classical descriptions do not establish clinical efficacy; see NCCIH’s evidence overview.
Red flags first: the practitioner's safety frame
The following examples need medical assessment; this list is not exhaustive and does not replace age-appropriate local guidance:
- a sudden, worst-ever headache reaching maximum intensity within minutes;
- headache with fever, stiff neck, a non-blanching rash, or altered consciousness;
- headache with weakness, numbness, speech difficulty, visual loss, unsteadiness or a seizure;
- headache after a head injury, or in a patient on anticoagulants;
- a new or changed headache after the age of fifty, or in a patient with cancer or immune deficiency;
- headache that wakes the patient, is worse lying down, on coughing or straining (bearing down), or is progressively worsening over days;
- headache in pregnancy, especially with raised blood pressure, swelling or visual symptoms;
- headache with eye pain, a red eye or halos around lights.
NICE CG150, assessment section lists features that call for evaluation and possible investigation or referral. Use medical assessment and current local guidance for management; neither a familiar remedy picture nor a previous similar headache excludes a serious cause.
Why headache is a teaching case
Two fictional records that both say “frontal headache” may lead to different index entries if one records motion aggravation and the other records relief from pressure. That difference teaches how the repertory organizes words; it does not determine diagnosis or which treatment a patient needs. Record the full path and inspect the underlying source before interpreting the result.
Belladonna — throbbing, sudden, red
Classical source description. The Belladonna headache comes on suddenly, often in the afternoon, and throbs: a congestive, pulsating pain, usually frontal or temporal and often right-sided, with a hot red face, dilated pupils and sometimes a high fever. It is worse from the slightest jar, from noise, light, stooping and lying flat, and better from firm pressure and from sitting propped up; the sun and a cold draught to the head are both causes. Kent gives Belladonna the top grade under Head, pain, pulsating (98), bursting (107), Forehead (249), Occiput (231), Temples (206), pressing (203), jar, from any (55), noise, from (72), light, from (45), sun, from exposure to (42), motion, from (136), pressure, external, ameliorates (83), menses, during (90) and cold, becoming, from (40). The Belladonna profile covers the general state.
Bryonia — bursting, worse from any motion, thirsty
Classical source description. Bryonia is the headache of stillness. The pain is bursting or splitting, frontal or occipital, worse from the least movement — turning the eyes, stooping, coughing, even talking — and better from lying perfectly still and from firm pressure. The patient is irritable, wants to be left alone, is thirsty for large quantities of cold water at long intervals, and is often constipated with dry lips. It comes on slowly, is worse in the morning on first moving, and accompanies influenza and gastric upsets. Kent lists Bryonia top-grade under Head, pain, bursting (107), motion, from (136), jar, from any (55), pressure, external, ameliorates (83), lying, ameliorates (61), Forehead (249), Occiput (231), bursting, coughing, on (27), sun, from exposure to (42) and cold, becoming, from (40). The Bryonia profile has the full picture.
Gelsemium — heavy band from the occiput, better for urination
Classical source description. Gelsemium's headache begins in the nape or occiput and spreads forward over the head like a band, with dullness, heaviness of the eyelids, dizziness and a sense of the head being too heavy to hold up. Vision may blur before the pain. It follows anticipation, bad news or the onset of influenza, is worse from the heat of the sun and from mental effort, and is relieved by a profuse flow of urine and, more slowly, by sleep. The patient is thirstless and wants to be left alone in the dark. Kent gives Gelsemium the highest grade under Head, pain, Occiput, extending to forehead (41), urination, profuse, ameliorates (10) and Occiput (231), and the second grade under light, from (45), jar, from any (55), lying, while (72) and sleep, after, ameliorates (19). The Gelsemium profile sets out the four Ds.
Nux vomica — the morning after
Classical source description. The Nux vomica literature describes symptoms reported after late work, lost sleep, alcohol, coffee, rich food or mental strain, waking with a dull, heavy or splitting pain in the occiput or over the eyes, with nausea, sour taste, irritability and intolerance of noise, light, odours and being spoken to. It is worse in the morning, from mental exertion, from stimulants and in the open air, and better from rest, warmth and a short sleep. Kent lists Nux vomica top-grade under Head, pain, morning (156), pressing (203), pressing, Forehead (198), Forehead, above eyes (171), Occiput, extending down back of neck (29), cold, becoming, from (40), and second-grade under periodic headache, every day (29), motion, from (136) and noise, from, footsteps (5). The Nux vomica profile has the constitution.
Natrum muriaticum — hammering with the sun, ten till three
Classical source description. Natrum muriaticum's headache is hammering or bursting, as from a thousand small hammers, over the eyes or through the whole head, coming with the sunrise, worst from ten in the morning to three in the afternoon, and easing as the sun goes down. It comes at or after menses, after grief, from eye strain and from reading, with zigzags or blindness before the pain, and is relieved by sleep and by lying in a dark room; consolation makes the patient worse. Kent gives Natrum muriaticum the top grade under Head, pain, pulsating (98), bursting (107), bursting, Forehead (47), pressing (203), menses, during (90), periodic headache (62), sleep, after (104), pressure, external, ameliorates (83) and bursting, coughing, on (27). The Natrum muriaticum profile covers the grief picture behind it.
The supporting cast
Classical source description. Glonoine. The historical description includes headache after sun or heat exposure: sudden, violent, pulsating, bursting, with the head feeling enormously enlarged and the blood surging upward, worse from the sun, from heat, from stooping and from any jar, better from cold applications and from uncovering the head. Suspected heatstroke is an emergency, not an indication for this source exercise. Top grade under Head, pain, sun, from exposure to (42), pulsating (98), bursting (107), jar, from any (55), pressing, Temples (167) and menses, during (90).
Classical source description. Sanguinaria. The recorded right-sided periodic headache that begins in the occiput in the morning, climbs to settle over the right eye by midday, and is relieved only by sleep or by vomiting; often weekly. Top grade under Head, pain, periodic headache (62), Occiput, extending to forehead (41), and second grade under sleep, after, ameliorates (19), vomiting, ameliorates (18) and pressure, external, hard, ameliorates (11).
Classical source description. Iris versicolor. The weekend or holiday migraine that comes with blurred vision, bilious vomiting and burning acidity, in a patient who is worse from rest after a week of strain. Top grade under Head, pain, vomiting (16) and second grade under motion, ameliorates (57). The Iris profile covers the gastric picture.
Classical source description. Spigelia. The left-sided stitching or burning headache that starts in the occiput and settles over the left eye, follows the sun, and is worse from the least motion, noise and stooping; often with facial neuralgia or palpitation. Top grade under Head, pain, one side (172), and among the highest under the left-sided sub-rubrics of the Forehead.
Classical source description. Silica. The headache that starts in the nape, rises over the head to the eyes, comes from cold, mental strain or lost sleep, and is relieved by wrapping the head warmly and by pressure. Top grade under Head, pain, Occiput, extending to vertex (20), jar, from any (55), periodic headache (62), cold, becoming, from (40) and light, daylight (5).

Running a source comparison in the repertory
Use a fictional record for this exercise. Verify the full rubric path, remedy identity and source-specific grade. Counts and grades describe the reference; they do not measure treatment effectiveness.
For the fictional record, compare a location rubric, documented modalities and any reported context:
- Head, pain, Forehead (249), Occiput (231), Temples (206) or one side (172) as the base; for a band from behind, Occiput, extending to forehead (41).
- The motion modality, which does the biggest single cut: motion, from (136: Belladonna, Bryonia, Carbo veg, Ledum, Mezereum, Nitric acid) against motion, ameliorates (57: Rhus tox, Iris, Lycopodium, Pulsatilla).
- The relieving modality the patient names unprompted: pressure, external, ameliorates (83), urination, profuse, ameliorates (10), sleep, after, ameliorates (19), vomiting, ameliorates (18), cold applications, ameliorate (50), lying, ameliorates (61).
- Reported context or timing: sun, from exposure to (42), menses, during (90), morning (156), periodic headache (62), cold, becoming, from (40), sleep, after (104).
- A general to confirm: Stomach, thirst, large quantities (Bryonia) or thirstless (Gelsemium, Pulsatilla), Mind, consolation, aggravates (Natrum muriaticum), Mind, irritability (Nux vomica).
All of these rubrics are in Kent's Repertory, free to search on Similia, and the repertorisation guide shows how to weight a modality against a location. Compare the source’s descriptions of lying flat in Belladonna and Bryonia. A difference in the text is not a medical diagnosis or evidence that either remedy will help.
