What is Picricum Acidum?
Origin and source. Picricum acidum is prepared from picric acid (trinitrophenol), a yellowish crystalline compound historically used as a dye and explosive and studied medically for its effect on the nervous system. In homeopathic pharmacy the acid is carried through serial dilution and succussion, yielding a preparation defined by its traditional symptom picture rather than by any material dose of the original substance.
Preparation in homeopathy. As with all homeopathic remedies, picricum acidum undergoes serial dilution and succussion. The final preparation is highly diluted; what remains is a remedy characterised by its constitutional profile in the materia medica, not by any chemical residue.
Historical place in homeopathy. Picricum acidum is a member of the "acid" group in the materia medica, alongside phosphoric acid and nitric acid, and is classically the remedy of spinal and nervous exhaustion — the "tired to death" state with preserved consciousness. It is contrasted with gelsenium (which also weakens but with heaviness and drooping) and with plumbum (which paralyses with contraction). It is a frequent compare where weakness is out of proportion to any disease.
Key Characteristics
- Spinal / nervous exhaustion — a deep, bones-tired prostration centred on the spine and limbs; "can hardly move."
- Mentally clear but physically collapsed — the mind stays sharp while the body fails; exhaustion after the least exertion.
- Bruised, aching, paralytic weakness — limbs feel beaten, sore, and weak, especially the legs; a "paralytic" heaviness.
- Weakness after exertion — even minor effort brings disproportionate collapse; must lie down.
- Aching in the back and limbs — as if bruised or beaten; worse from motion and standing.
- Skin and urinary considerations — a traditional place in certain yellowish skin and urinary-tension states within the individualised picture.
- Worse from exertion, standing, motion; better from rest, lying down.
Traditional Symptom Picture
In homeopathic practice, picricum acidum is traditionally considered when a person's symptom pattern includes the themes above. The picture is built system by system:
Head
Dull, heavy head with mental fatigue; the person can think but is physically spent. Aching at the back of the head and neck, as if bruised.
Eyes
Tired, aching eyes; a traditional consideration in the neurasthenic eye-strain picture within the individualised picture.
Nose
Occasional catarrh; less prominent than the nervous features.
Throat
Dry, scraped; a tired, weak swallowing in the exhausted state.
Skin
A traditional consideration in yellowish or sallow discolouration and in certain sluggish skin states within the individualised picture.
Mind
The striking feature: mental faculties remain intact while the body is prostrate. The person is conscious, often anxious about the weakness, but unable to move or act. There is weariness "to the point of despair" without clouding of sense. Thought is clear yet the will to execute is gone; the smallest intention — to stand, to step, to speak — is met by a wall of exhaustion. This is a traditional constitutional sketch, never a label applied to a disease.
Constitution & temperament
The picricum constitution is the "burnt-out" nervous-exhaustion type — one who collapses from spinal fatigue yet stays mentally aware. These are often people who have driven themselves to the edge: students, overworked minds, or convalescents who cannot rebuild strength. It differs from the depressed, weepy phosphoric-acid type (whose mind clouds with grief) and from the heavy, drooping gelsenium type (whose sensorium itself is dulled). The picricum person knows exactly what they cannot do. The remedy is read as part of the whole person, not as a disease treatment.
Urinary
A traditional consideration in scanty or turbid urine and in urinary-tension states within the individualised picture; the weakness may extend to the bladder.
Digestive
Loss of appetite with the exhaustion; a weak, sinking feeling; the digestive fire is low in the prostrated state.
Liver
Sluggish picture with a tired, aching right hypochondrium; a traditional consideration in hepatic exhaustion within the individualised picture.
Extremities
The leading sphere. Bruised, aching, paralytic weakness of the limbs — especially the legs and lower back — with a sense of being beaten. The person must sit or lie; standing and walking are exhausting.
Modalities
Better: rest, lying down, quiet. Worse: exertion, standing, motion, mental or physical work.
Every symptom is read as part of an individual's complete picture. Two people with the same diagnosis may receive different remedies.
Conditions Where Practitioners May Consider Picricum Acidum
The conditions below are ones where homeopathic practitioners traditionally discuss picricum acidum as one possible remedy among many, selected by the individual's complete symptom picture. Each links to its live condition overview and (where available) its in-depth guide.
Homeopathy individualises; responsible care includes medical diagnosis where indicated.
Common Patient Questions
- "I'm so weak I can barely stand, but my mind is fine — could this be picricum?" — a clear mind with physical collapse is a classical combination, but only a qualified homeopath can confirm the full pattern after individualised case-taking.
- "Why does the least effort exhaust me?" — disproportionate weakness after exertion is a traditional keynote; this is exactly what a homeopath assesses.
- "Is it an acid I should avoid eating?" — no; homeopathic picricum acidum is a specifically prepared, highly diluted remedy, not dietary acid.
- "How do I know the potency?" — potency is individualised by the practitioner, not chosen from a fixed chart.
Potencies
Homeopathic preparations use potency scales indicating dilution and succussion:
- 6C / 30C — lower Centesimal potencies, traditionally for milder or more superficial patterns.
- 200C — a higher potency, traditionally for deeper or constitutionally-matched cases.
- 1M — a high potency used occasionally in individualised practice.
- LM — a gentle, sequential potency format for sensitive individuals.
Potency is individualised — chosen by the practitioner from your constitution and response. We do not advise self-selection of potency.
Dosage
Homeopathic dosage varies by individual: constitution, acuity, potency, and response. A practitioner sets and adjusts the plan. Repeated self-dosing is discouraged as it can obscure the remedy's effect.
Safety & Precautions
- Pregnancy & breastfeeding: discuss with your physician and a qualified homeopath.
- Children: practitioner-led remedy selection.
- Existing conditions / medications: homeopathy is a distinct system of medicine; keep your physician informed and continue prescribed treatment as needed.
- Urgent care: sudden severe weakness, difficulty breathing, chest pain, neurological symptoms — seek conventional medical care promptly.
Side Effects
- Homeopathic aggravation: a brief, temporary intensification may occur as the remedy acts; judged by the practitioner.
- Stop & consult if symptoms worsen persistently or new severe symptoms appear.
Who May Benefit?
Framed as symptom patterns, not diagnoses: a spinal/nervous-exhaustion constitution with mentally-clear but physically-collapsed weakness, bruised aching limbs, and disproportionate prostration after the least exertion. Benefit is individual; a matching pattern — not a disease label — is what the practitioner assesses.
Who Should Avoid Self-Medicating?
Infants/young children, pregnant/breastfeeding women without guidance, sudden severe weakness, chest pain, neurological symptoms, severe infections, persistent worsening symptoms. Weakness can signal emergencies — medical care comes first.
Picricum Acidum vs Other Remedies
Comparison tables show why remedy choice is individualised — pattern contrasts, not rankings.
Picricum Acidum vs Phosphoric Acid
Phosphoric acid is mentally dulled, weepy, and apathetic from loss/grief — see phosphoric-acid for the contrast.

Gelsenium is heavy, drooping, trembling, drowsy, with dulled sensorium — see gelsenium for the distinction.
