Indigestion

Indigestion sends more people to the homeopath than almost any other complaint, and the same word covers half a dozen entirely different pictures. The differential below sits close to the materia medica and asks the questions that decide the prescription: what was eaten, what the appetite does, where the wind sits, and how the patient bears it.

Understanding Indigestion Through a Homeopathic Lens

A stomach does not fail on its own. The stomach reacts, and the reaction, whether it comes out as belching, as loathing of food, or as a pain that arrives at exactly a quarter past eleven, is a self-expression of the organism trying to right itself. Hahnemann is emphatic in the Organon that the practitioner reads these expressions as one image and not as parts of a broken machine. Kent extends the point in his lectures on stomach cases. The appetite, the thirst, the taste in the mouth and the demeanour that goes with them belong together, and the prescription is made on that whole.

This matters because indigestion is not a disease. It is a story the digestive tract is telling, and the story of the office worker who lives on strong coffee is not the story of the child who has eaten too much ice cream, is not the story of the elderly patient bloated for a fortnight after a bout of dysentery. The Latin name over the counter (Carbo, China, Nux) is only a shorthand for a picture. Get the picture right and the remedy chooses itself.

Six preparations do most of the work in day-to-day practice: Nux vomica, Pulsatilla, Ipecacuanha, Sulphur, China officinalis and Arsenicum album. They are not interchangeable. Confusing one for another is the commonest reason a well-indicated case fails to move.

Top Remedies for Indigestion

Nux Vomica

Keynote: the overworked, overstimulated, irritable patient whose stomach protests at the coffee, wine and rich food that keeps them going.

The picture is familiar and it will walk into any consulting room in any city on any weekday. Thin, quick, brunette by preference; anxious about business; ambitious; sensitive to noise, to light, to a colleague reading over their shoulder. They came home late, ate too much, drank too much, slept too little, and woke at five to a sour taste and a headache that ran into a queasy morning. Every harmless word offends. Every little noise frightens. The stomach feels loaded an hour after eating, the belching is bitter, and there is a great deal of ineffectual urging to stool, that particular sensation that something must pass and nothing does.

Clarke and Hering both stress the constipation with the constant desire, and Boericke gives the exact register: sedentary habit, stimulants, indoor life, irritable temper. Nux vomica is the remedy of the debauchee and the workaholic, and both are cured on the same principle. The zealous, fiery temperament that Murphy compiles from the older authorities is not a moral judgement; it names a real type of patient at the consulting-room desk.

A woman in her forties, running a small business, came for what she called "acid stomach". She had eaten nothing unusual, she said, then paused and added that she had increased her coffee to five cups a day because a supplier had failed her and she had been at the desk until two most nights that week. Her tongue was thickly coated at the back. She was angry with her partner for consoling her about the supplier. One dose of 30C at bedtime cleared the picture in two days; the coffee she cut down herself once she felt like it.

Worse: morning; after eating; cold; open air; stimulants; mental exertion; noise; slight touch. Better: warm room; a brief nap if allowed to finish it; hot drinks; passing stool; loosening clothing.

Prescribe 30C on retiring for the acute picture and repeat once or twice if needed. In the deeper chronic dyspepsia of the same type, 200C in single dose, then wait.

Pulsatilla

Keynote: indigestion from fats, pastry, pork and ice cream in a mild, tearful, thirstless patient who wants air and company.

The Pulsatilla stomach cannot manage rich food and does not try to hide the fact. An hour after a birthday cake or a slice of pork the patient is heavy, distended, chilly and short of breath, and the room feels too close. They want the window open even though they are shivering. They want to be held. They do not want water; the mouth may be dry and they still refuse the glass. The tongue often carries a thick white or yellow coat. Any coincident mucus-membrane discharge, a coryza, a leucorrhoea, an otitis, will be bland, thick and yellow-green, and this alone can point to the remedy when the stomach picture is ambiguous.

Symptoms shift. Boericke calls it a weathercock remedy and the description holds. A patient will complain of one pain, then another, then have lost the first and be quite well in that spot; the stool this morning is unlike the stool last night. In children the picture is unmistakable: the child who wants to be carried slowly, who bursts into tears at any word from a stranger, who weeps her way through the whole consultation and who cannot bear ice cream at parties without being sick before bedtime.

Worse: rich or fatty food; ice cream; pork; pastry; warm closed rooms; evening; getting the feet wet. Better: open air; slow gentle motion; cold applications; consolation; uncovering.

Give 30C after the offending meal, or 200C for the constitutional child in whom the pattern repeats.

Ipecacuanha

Keynote: persistent nausea not relieved by vomiting, with a clean or nearly clean tongue.

Ipecac is the remedy of the stomach that will not settle. The nausea is constant and it dominates the picture. Vomiting comes and brings no relief. As soon as the vomit is over the desire returns, and the patient is left exhausted and no better. The characteristic sensation, given verbatim in Boericke and repeated by Hering, is as if the stomach were hanging down relaxed. Salivation is profuse. The tongue, remarkably, is clean or only slightly coated, and this single sign will separate Ipecac from almost every other stomach remedy in the book.

The provocations that lead to an Ipecac case are the ones every parent knows: cold drinks on a hot afternoon, an ice cream too soon after lunch, unripe fruit, pork, pastry, a child stuffed at a party. Nausea and shortness of breath travel together, and the child gasps a little between the retches. In pregnancy the same picture appears as unrelenting morning sickness with no interval, and it is here that Ipecac earns its keep.

A four-year-old girl was brought after a summer picnic. She had vomited twice on the drive home, twice more at the door, and by evening was retching every ten minutes with nothing left to bring up. Her tongue was pink and clean. She would not lie down and did not want to be held. One dose of 30C in water, sipped over an hour, stopped the retching; she slept and woke well.

Worse: overeating; rich food, pork, pastry, unripe fruit; ice cream; cold drinks; warm moist weather; least motion during the nausea. Better: open air; rest in an upright position; a short interval between the fits.

Give 30C in water, teaspoon doses, for the acute case; 200C for stubborn morning sickness once the picture is confirmed.

Sulphur

Keynote: chronic dyspepsia in a hungry, heat-intolerant patient with an empty sinking sensation late morning and skin that itches at night.

Sulphur rarely fits the acute stomach complaint. It very often fits the chronic case that has been half-treated for years. The stomach empties into a sensation the patient describes as a hole, Hahnemann's empty, sinking feeling, coming on around eleven in the morning and demanding food that will not fully satisfy. The patient is hungry and always tired; assimilation is poor; the belly may be big while the limbs are thin, particularly in children. Heat is intolerable, so much so that the feet burn at night and must be pushed out from under the covers. There is nearly always something on the skin, a chronic itch, an eczema, an old boil that never quite closes.

Kent's description of the Sulphur temperament is unkind but recognisable and it prescribes cases. The ragged philosopher, absorbed in metaphysical questions, indifferent to appearances, averse to being washed, quarrelling with anyone who offers advice. In the consulting room this presents as the patient who has read everything, tried everything, and has an opinion on each of them. Their indigestion has been going on for a decade. They cannot say when it began.

Sulphur is also the remedy for complaints that relapse, and for the picture that stalls under a well-selected simillimum, which is Kent's rule of the deficient reaction. Boericke lists it plainly for chronic dyspepsia with all the sinking, and Murphy compiles its use across the whole gastrointestinal register.

Worse: 11 a.m.; heat of the bed; standing; bathing; suppression of eruptions; after milk; sweets. Better: open dry air; lying on the right side; motion; warm applications to the abdomen.

Give 30C weekly in chronic dyspepsia while other treatment is under way; 200C in single dose when the case needs to be opened. Do not repeat mechanically.

China Officinalis

Keynote: great flatulent distension of the whole abdomen, not relieved by belching or passing wind, in a patient debilitated by loss of fluids.

The China stomach is bloated and the bloating dominates. Every meal, however small, produces gas that fills the abdomen and cannot be discharged. The patient belches and it does no good. They pass flatus and it does no good. The relief that Carbo veg patients get from eructation is exactly what China patients do not get. Bending double eases it a little, motion eases it a little, but touching the abdomen is unbearable; the tenderness lies right at the surface.

The context matters enormously. China is the remedy after loss of vital fluids: after a haemorrhage, after a long diarrhoea, after a course of dysentery caught on a journey, after prolonged breastfeeding, after any drain that has left the patient hollow. The Peruvian bark from which it is drawn was the classical fever remedy of the tropics, and the indigestion it treats often follows a fever, an infection or a long convalescence. Traveller's diarrhoea in the settled phase, when the acute is over and the patient cannot eat without bloating for weeks after, is a picture few other remedies fit as well.

Attention to the potency register is decisive here. The mother tincture and low decimals of Cinchona carry real pharmacological action; this is the herbal drug from which quinine was isolated, and its dosimetric cautions apply in that form. What is prescribed in classical practice at 30C and above contains no alkaloid, and the drug data do not apply; what acts is the dynamic preparation, meeting the patient on the totality of the case.

Worse: touch and pressure over the abdomen; after meals however small; at night; loss of fluids; fruit; bad water; draughts. Better: hard steady pressure (as against a table edge); bending double; warmth; open air walking slowly.

Give 30C two or three times daily in the acute post-diarrhoeal picture; 200C where the debility is marked and the case is clear.

Arsenicum Album

Keynote: burning stomach pain with anxiety, restlessness and midnight aggravation, better for warm drinks in small sips.

Arsenicum is the remedy of gastroenteritis at its most alarming and of dyspepsia at its most anxious. The patient has burning pain, what Hering describes as burning like coals of fire, relieved paradoxically by warmth. They are restless and cannot stay in the bed, moving from chair to chair, and at the same time they are exhausted out of proportion to the illness. They are frightened. They think they may not recover from a simple stomach upset. They want somebody in the room.

Thirst is characteristic and diagnostic. Arsenicum drinks little and often, sips of warm water taken every few minutes, where a Bryonia patient will drain a full glass at long intervals. The face is pale and pinched. Any food is refused; the sight of it may bring on the nausea. Vomiting and diarrhoea occur together, both burning, both offensive, and the exhaustion after each episode is marked.

Food poisoning is the classical acute indication. Boericke names it; Clarke gives the whole clinical range; Hering emphasises the fastidious, orderly temperament that runs underneath even the acute case. A man returning from a summer wedding buffet, gripped at two in the morning by burning stomach cramps and unable to lie flat for fear of vomiting, took 30C in water on his wife's suggestion and was sleeping by four. He mentioned the next week that he had also stopped rearranging the kitchen cupboards at midnight, which she had not connected to the same remedy but which the materia medica would have predicted.

Worse: after midnight, especially 1 to 2 a.m.; cold food and drinks; sight or smell of food; being alone; lying flat. Better: warm drinks in small sips; warm applications; company; sitting propped up; motion despite the weakness.

Give 30C in water, teaspoon doses, for the acute gastroenteric picture; 200C in the anxious chronic dyspepsia where the whole temperament matches.

Clinical Guidance

Take the case on what the patient volunteers before asking the pointed questions. The value of the differential above lies in what the patient tells you unprompted, that they cannot bear the smell of food, that they must sit up, that the coffee they usually love now disgusts them. These are the modalities and concomitants on which the prescription turns.

Two practical rules save time. First, distinguish the acute episode from the chronic ground. A single bad meal in an otherwise well patient calls for the acute remedy in 30C, once or twice. A pattern repeating for years asks for the constitutional prescription, more often in 200C and single-dose, with time given to act. Do not mix the two logics in the same session.

Second, resist the impulse to prescribe on the pathology alone. Nux vomica and Sulphur both cover chronic dyspepsia. Pulsatilla and Ipecacuanha both cover vomiting after rich food. The tongue, the thirst, the temperament and the modalities decide, not the diagnosis on the referral letter. Where a case is genuinely unclear, the older authorities, Boenninghausen especially, recommend waiting and observing rather than prescribing on a partial picture. A wrong remedy given quickly is harder to undo than the wait.

Concomitant conventional medication is the patient's decision and their prescriber's. The dynamic preparation works alongside a proton-pump inhibitor as readily as without one, and the improvement, when it comes, tends to show first in the patient's tolerance of food, then in the loss of the modality that brought them in, and only last in the appearance of the belly.

Frequently Asked Questions

How quickly should a well-chosen remedy act in acute indigestion? Within one to three hours in the true acute case, whether that is the sipped dose of Arsenicum, the pellet of Nux vomica at bedtime, or the Ipecac in water for the vomiting child. If nothing has shifted by the next morning, the picture was probably not the one you thought it was; retake the case rather than repeating the dose.

Is it safe to prescribe these remedies alongside conventional treatment for reflux or ulcer disease? Yes. At 30C and above there is no molecule of the source substance present, and the interaction question that governs herbal or drainage prescribing does not arise. The mother tincture and low decimals of the same remedies belong to a different register and are not what is meant here.

What role does the tongue play in choosing between these remedies? A great deal. The clean or nearly clean tongue of Ipecacuanha in a nauseated patient is almost pathognomonic; the thickly coated back-of-tongue in Nux vomica points hard; the yellow-white coat with the thirstless mouth suggests Pulsatilla. Kent gives the tongue a whole chapter in the repertory for good reason.

What potency should a home prescriber keep for stomach upsets? 30C of Nux vomica, Pulsatilla, Ipecacuanha and Arsenicum album covers most acute domestic indigestion. Chronic constitutional prescribing, and the deeper use of Sulphur and China, belongs in the hands of a trained practitioner.
