Anacardium orientale — the marking nut — is the remedy of the divided will. Kent gives the patient's own words first — "Feels as though he had two wills" — and then the old image for the same state: "Hallucinations: a demon sits on one shoulder and an angel on the other."
Boericke opens with the type rather than the drama: "The Anacardium patient is found mostly among the neurasthenics; such have a type of nervous dyspepsia, relieved by food; impaired memory, depression, and irritability; diminution of senses (smell, sight, hearing)." Add Boger's two great generals — "Mental and physical LACK OF POWER" and "Repeated, DULL PRESSURE, as of a plug, or band" — and the skeleton of the remedy is complete.
The medicine is prepared, Clarke records, from Semecarpus anacardium of the Anacardiaceæ, the East Indian marking nut: "layer of nut between shell and kernel triturated." It shares much with "its botanical relatives, the different species of Rhus, especially in its action on the skin, muscles, and joints" — Kent calls it outright "an antidote to Rhus poisoning."
In practice Anacardium lives among students and overworked professionals: brain-fag, memory that suddenly fails, confidence that has drained away, a stomach that only feels right while eating. Clarke: "It has at any rate won for itself a reputation in 'examination funk' and allied conditions."
This guide profiles it for clinical study from Boericke's Materia Medica, Clarke's Dictionary, Boger's Synoptic Key, Lippe's Keynotes and Kent's Lectures. The originals can be read in full — Clarke's Anacardium, Boericke's Anacardium and Kent's Anacardium — through Similia's free digital materia medica.
The Anacardium Constitutional Type
The ground tone is weakness — of mind, memory, senses and muscles at once. Lippe's keynotes read like a list of deficits: "Loss of memory." "Trembling debility and paralytic weakness." "Diminution of the senses (smell, sight and hearing)." Boger adds "Tremulous; on slight exertion" and "Dulled emotions, sense of hearing, sight, touch, etc."
On this weakened ground stands a person who distrusts himself. Boericke: "Aversion to work; lacks self-confidence." Kent: "looks for thieves, expects enemies, fears everything and everybody", and — his blunt summary — "Cowardly in the extreme." Boericke records the accompanying "anxiety when walking, as if pursued."
The symptoms come and go in a way the sources found remarkable. Boericke: "Intermittency of symptoms." Lippe: "Periodicity of the symptoms." Clarke quotes the proving: "The attacks ceased for one or two days, and then continued again for a couple of days" — an indication on which Custis cured a case of periodic sleeplessness.
Two causations stand in Clarke's schema: "Checked eruptions. Examinations." The first ties Anacardium to its Rhus-like skin; the second to the study desk.
Mental and Emotional Picture
Two wills. Kent: "He hears voices commanding him to do this or that, and seems to be between a good and an evil will... So there is a controversy between two wills, between two impulses." Clarke's schema states it exactly: "State as if there were two wills, one of which rejects what the other requires." Boericke condenses: "thinks he is possessed of two persons or wills." With it comes irresolution — Kent: "He is in a continuous controversy with himself. Irresolution marks his character."
Sudden memory loss. Boger: "BAD MEMORY; suddenly forgets names, etc. Brain-fag." Kent: "Weak memory. Forgetful of things in his mind but a moment ago." Clarke: "Loss of memory is very marked", and adds "deafness with loss of memory" — the failing memory sitting among failing senses.
Want of confidence. Boericke: "Lack of confidence in himself or others. Suspicious." Boger: "Cowardly and neurotic... at odds with himself"; "contradictory impulses."
Irritability with profanity. Recorded symptomatology, stated as the sources state it: Boericke lists an "irresistible desire to swear and curse"; Clarke notes "a great propensity to swear and blaspheme in persons not usually addicted thereto"; Lippe's keynotes are simply "Maliciousness. Swearing." Kent records the graver pole for professional assessment — "Slight causes make him excessively angry. A strong feature is that all moral feeling is taken out of him" — and Boericke's "absence of all moral restraint" marks the same recorded extreme.
As if in a dream. Kent: "All his senses seem to vanish and he gropes around as if in a dream." Clarke's fixed ideas include "that there is no reality in anything, all appears like a dream"; "that a stranger is constantly by his side"; and the poignant "her husband is not her husband, her child is not hers; fondles, then pushes them away."
Clairaudience and illusory smells. Boericke: "Clairaudient, hears voices far away or of the dead." Kent: "Illusions of smell, burning timber, pigeon's dung" — Clarke cured a man with "a smell of burning wood in his nose, remaining after influenza."
Gloom. Boericke: "Profound melancholy and hypochondriasis, with tendency to use violent language." Kent: "Fears some dreadful thing will happen. Morose, sulky, sullen."
Physical Affinities
The plug and the band
Clarke elevates this to the leading physical general: "A very characteristic sensation is a pressing or penetrating pain as from a plug, which may occur in any locality... and whenever present Anacardium will probably be the remedy." Boericke maps its stations — head ("Pressing pain, as from a plug"), orbit ("Pressure like a plug on upper orbit"), ears, intestines ("Pain as if dull plug were pressed into intestines"), chest ("Pressure in chest, as from a dull plug"), even the glutei. Kent: "Sensation here and there of pressure, described as if a plug, all through the body, in the head, eyes, in the navel and down the spine."
The companion sensation is constriction: "Sensation of a hoop or band around the body or about any part is a leading symptom" (Clarke); Lippe has the same, and Boericke the "knees feel paralyzed or bandaged."
Digestion
The famous amelioration: "Empty feeling in stomach; eating temporarily relieves all discomfort. This is a sure indication, often verified" (Boericke). The relief is genuine but timed — Boger: "Gastric pain > eating, but < again in 3 hours"; Clarke: "Symptoms disappear after dinner; but begin again in two hours." Boericke adds the hurried manner: "Apt to choke when eating or drinking. Swallows food and drinks hastily." Clarke extends the modality to pregnancy: "Morning sickness of pregnancy > by eating, but returns soon after."
Rectum
A plug again, now functional: "Ineffectual desire; rectum seems powerless, as if plugged up; spasmodic constriction of sphincter ani; even soft stool passes with difficulty" (Boericke). Boger: "Rectum feels plugged; can't evacuate even a soft stool."
Head and special senses
Headache "worse after mental exertion" and "better during a meal" (Boericke); Clarke confirms "Headache < by mental exertion; > by eating" and notes it is also better lying down. Vision carries a signature distortion — "Objects appear too far off" — and hearing dulls behind the plugged ears.
Extremities and skin
"Paralytic weakness" runs through the limbs: trembling hands, "sensation of paralysis in the knees", legs "as if they were bandaged" (Clarke). Two palm signs are worth memorising: "Warts on palms of hands" (Boericke) and Clarke's "clammy sweat in the palms of the hands." The skin behaves like its botanical cousin: "Intense itching, eczema, with mental irritability; vesicular eruption... eruption like that of Poison-Oak" (Boericke); Kent: "The eruptions are like Rhus in many respects"; Lippe: "Itching of the skin, worse from scratching."
Key Modalities
Worse from:
- Mental exertion — Boger capitalises it as the first aggravation
- Emotions — Boger: "Anger, fright, care, etc."
- The return after eating — "long after eating" (Boger); symptoms "begin again in two hours" (Clarke)
- Lying on the side, rubbing, grasping — Lippe: "Aggravation when lying on the side, from rubbing, and from taking hold of anything"
- Stepping hard (Boger)
- Draughts, cold, open air — Boger lists all three; Clarke: "chilliness, liability to take cold, sensitiveness to draughts"
- Morning, and evening to midnight (Clarke)
Better from:
- Eating — every source; the remedy's grand amelioration
- Warmth — Clarke: "> from warmth"; Boger: "Hot bath", and "Easily chilled, > sunshine"
- Lying down — for the headache (Clarke)
One divergence to note honestly: Boericke's modality line reads "Worse, on application of hot water", while Boger and Clarke record general relief from warmth — a reminder to take the modality from the patient, not the book.

- Rhus-like vesicular eruptions with intense itching; warts on the palms
Clinical Applications
Clarke's clinical list places Anacardium across brain-fag, examination funk, dyspepsia, loss of memory, hypochondriasis, paralysis, eczema, warts and writer's cramp. The recurring clinical shapes:
Examination funk and over-study. The remedy's signature ground. Clarke reports Breyfogle's extensive use of it on Bayes' indications — "funk before examination", "nerve-exhaustion from over-study" — in nervous prostration.
Nervous dyspepsia. The eating-relieved gastralgia with its two-to-three-hour return, in the irritable, self-distrusting subject.
Constipation from rectal inactivity. The plugged, powerless rectum with ineffectual urging.
Memory weakness of the aged. Boericke lists "senile dementia" and "coryza with palpitation, especially in the aged" — recorded indications for professional assessment of the failing sensorium.
Mental states with the divided will. Kent: "Suitable in religious mania when the conflict between the external and internal will is kept up" — textbook territory, weighed with the full case.
Skin. Rhus-like vesicular eczema with intense itching; Boericke calls it "a valuable antidote to Poison-Oak."
Cough of nervous type. "Cough excited by talking, in children, after fit of temper" (Boericke); Clarke's whooping-cough note ends each paroxysm with "yawning and sleepiness."
Differential Diagnosis
Anacardium vs. Gelsemium. The two examination remedies divide cleanly. Gelsemium's funk is anticipatory paralysis — drowsy, trembling, weak, often with diarrhoea before the event. Anacardium's is cognitive collapse in a chronically overworked student: the memory "suddenly forgets", confidence is already low, the dyspepsia relieved by eating and the plug sensations complete the picture.
Anacardium vs. Lycopodium. Both are pillars of the want-of-self-confidence rubric with weak digestion. Lycopodium hides its self-distrust behind an imperious manner and fears undertaking, yet performs once started; Anacardium sinks into irritable self-distrust with failing memory and the recorded harshness of mood. Clarke lists Lycopodium among the remedies that follow Anacardium well.
Anacardium vs. Nux vomica. Clarke draws the gastric contrast exactly: "With Nux the pain is worst for two or three hours after a meal, during stomach-digestion, and is > when that is over; whereas with Anac. it is just then (when digestion is complete) that the pain is worst, and it lasts until the next meal, which again > for a time." Same irritable dyspeptic ground, opposite clock.
Anacardium vs. Staphysagria. Both suit sensitive, easily offended subjects marked by suppressed emotion. Staphysagria swallows its indignation and suffers from the suppression; Anacardium's tension discharges as cursing and contradiction of will. Boger cross-references the tremulous weakness of the knees between the two remedies.
Repertorisation Tips
These rubrics carry Anacardium in high grade:
- Mind; WILL; contradiction of
- Mind; MEMORY; weakness of
- Mind; FORGETFUL
- Mind; CONFIDENCE; want of self-confidence
- Mind; CURSING; desire to curse
- Mind; DELUSIONS; double, of being
- Mind; ANXIETY; walking, while; as if pursued
- Generalities; PLUG, sensation of a
- Generalities; CONSTRICTION; band or hoop, as from a
- Generalities; EATING; amel.
- Rectum; INACTIVITY of rectum
- Head; PAIN; mental exertion, from
Anchor on the general amelioration from eating together with a plug or band sensation — a pairing few remedies share — then confirm with the mental line: sudden memory weakness, want of confidence, contradiction of will. In a student's case, Clarke's causation "Examinations" is itself repertorial evidence. Our beginner's guide to repertorisation sets out the anchoring method in more detail.
