Remedies in the practitioner tradition for infant colic
Infant colic — crying more than three hours a day, more than three days a week, in an otherwise thriving baby — peaks around six weeks and resolves spontaneously in nearly all cases by four months. The classical materia medica treats the picture by the type and modality of the pain, the posture that relieves it, and the temperament of the distress, not by the diagnostic label.
Red-flag presentations
Colic is a diagnosis of exclusion. The following are red-flag presentations needing prompt assessment: fever in a baby under three months; bile-stained or projectile vomiting; blood in vomit or stool; a swollen, hard, or tender abdomen; episodes where the baby goes pale and draws up the legs in waves; breathing difficulty or blue lips; poor feeding or poor weight gain; or any presentation where parental instinct says something is seriously wrong.
The colic pictures
| Remedy | Core picture | Key modality |
|---|---|---|
| Colocynthis | Cramping waves; patient doubles up; relief from firm pressure on the abdomen | Better hard pressure |
| Magnesia phosphorica | Cramping; better from warmth and gentle rubbing | Better warmth |
| Chamomilla | Furious, angry crying; one cheek red, one pale; only carrying relieves | Better carried |
| Dioscorea villosa | Pain better arching backward — the reverse posture of Colocynthis | Better extension |
| Nux vomica | Irritable, constipated colic; ineffectual straining | Worse cold, over-stimulation |
| Lycopodium | Bloating and rumbling; worse late afternoon to evening | Worse 4–8 p.m. |
Colocynthis is the central colic remedy. The pain comes in cramping waves that drive the patient to bend double, with rapid relief from firm pressure on the abdomen — in the infant, this is the face-down position with pressure against the belly. Kent's keynote: "ameliorated by hard pressure."
Magnesia phosphorica shares the cramping modality but separates clearly on the relieving factor: warmth rather than pressure — a warm bath, a warm compress, gentle rubbing. Colocynthis and Magnesia phosphorica are the closest pair in this territory, differentiated by that single axis.
Chamomilla is distinguished by the temperament of the crying more than by abdominal signs. The picture is frantic, enraged distress — "great anguish and restlessness," a child "cross, ugly, and quarrelsome" — with the keynote that nothing relieves except constant carrying; the moment the baby is put down the screaming resumes. One cheek red and the other pale is a frequent concomitant.
Dioscorea villosa occupies the direct opposite of the Colocynthis posture: the picture improves from stretching out and arching backward, and is aggravated by bending double. This reversal is the primary differentiator, since the cramping character of the pain is similar in both.
Nux vomica covers the irritable, constipated picture: ineffectual straining at stool, oversensitivity to stimulation, and an irritable rather than enraged disposition — distinct from the frank fury of Chamomilla.
Lycopodium presents with distension and audible rumbling, the symptoms worse in the 4–8 p.m. window — which coincides with the usual evening peak of infantile colic, making the time modality the most useful discriminator here.
Differentiating the pictures
The primary discriminators in this region are posture and the relieving modality:
- Doubling up versus arching back — Colocynthis versus Dioscorea.
- Pressure versus warmth — Colocynthis versus Magnesia phosphorica.
- Carried-constantly fury — Chamomilla, distinguished by temperament rather than abdominal modality.
- Evening bloat with rumbling — Lycopodium, distinguished by the time aggravation.
- Constipated straining — Nux vomica, identified by the physical concomitant.
A secondary axis runs through the quality of the distress: Colocynthis is urgent, physically-driven distress that quiets rapidly once the pressure position is found; Chamomilla is disproportionate rage that no position resolves; Nux vomica is irritable over-sensitivity rather than outright fury.
These distinctions correspond to rubrics under Abdomen, pain, cramping and Abdomen, flatulence — rubrics you can work through directly in the free repertory. Colocynthis and Magnesia phosphorica appear under the same indications for menstrual cramping: the picture centres on the type of pain — cramping, intermittent, wave-like — and its modalities, not the age or sex of the patient.
