Quick Reference Facts
"Sulphuricum Acidum is described in traditional materia medica for internal trembling without visible shaking, hurried impatience, intensely sour regurgitations, and dark bruises from slight knocks."
Clinical Description
Sulphuricum Acidum (Sulphuric Acid) is a major deep-acting mineral acid remedy proved by Samuel Hahnemann. In classical homeopathic texts, it occupies a specialized therapeutic sphere characterized by profound physical debility, gastrointestinal hyperacidity, vascular fragility, and nervous exhaustion. Key features recorded in materia medica include an unmistakable keynote sensation of deep internal trembling throughout the whole body without any visible shaking of the limbs, extreme impatience, haste, and hurry where the patient cannot do anything fast enough, intense sourness of the stomach where all vomited matter and regurgitations are so excessively sour that they set the teeth on edge, dark blue or purpuric ecchymoses and petechiae from slight mechanical bruises (especially in aged, cachectic, or alcoholic subjects), and aphthous ulcerations of the mouth and esophagus.
Guiding Keynotes
- Historically described for profound sensation of internal trembling across the whole body without visible tremor
- Haste and hurry: extremely impatient, hurried in movements, and feels that everything must be done in an instant
- Excessive sourness: sour eructations, sour vomiting, and heartburn so intensely sour that it sets the teeth on edge
- Vascular ecchymosis: slight mechanical knocks or trauma leave large dark, purplish, black-and-blue ecchymoses and subcutaneous hematomas
- Severe aphthous stomatitis: painful bleeding ulcers of mouth and gums with foul breath and extreme salivation
- Craving for alcoholic stimulants with severe chronic dyspepsia and morning vomiting of alcoholics
Mental-Emotional Symptoms
- Hurried, irritable, and restless; fretful over the slightest delay
- Despondent and weeping, especially after physical exhaustion
- Aversion to answering questions; wishes to be left alone
Physical / Particular Indicators

- Profound weakness and trembling in the stomach with sinking feeling, relieved by sipping warm aromatic drinks

Clinical Safety & Potency Guidance
Crude concentrated sulphuric acid is a lethal caustic mineral acid causing catastrophic chemical burns, esophageal perforation, and tissue necrosis; source-specific toxicology guidance is required. A homeopathic dilution label does not by itself guarantee composition, quality, safety, or effectiveness. Acute corrosive ingestion, perforated peptic ulcer, acute upper gastrointestinal hemorrhage with hematemesis/shock, or severe thrombocytopenic purpura requires immediate emergency hospital resuscitation; this traditional profile must not delay proven care.
