Acidum sulphuricum
Made from sulfuric acid — the oil of vitriol of the alchemists, the battery acid of the modern world, and the classical remedy of trembling debility with the hemorrhage of the weak.
The whole picture, in one breath
Think of strength draining through a sieve: trembling weakness from the least cause, bruising and bleeding at the slightest touch, hiccups that will not stop, hot flushes with sweat that exhaust, and the sensation that the whole system is spent. The trembling, bleeding, exhausted acid: that is Sulphuric acid.
The substance, in plain words
Sulfuric acid is oil of vitriol — the alchemists' strongest water, the most-produced industrial chemical on earth, the battery in every car. Concentrated, it chars flesh and paper; in the old dilute pharmacy it treated 'debility with relaxation'; the proving gave the remedy its portrait of trembling, draining exhaustion.
The traditional picture Classical sources
The inner state
- Anxiety and hurried weakness. Anxious, hurried, yet too weak to sustain the hurry; the books paint the worn, trembling temperament.
- Irritability from weakness. Cross from exhaustion, worse in the morning.
- Despondency. Gloomy in the drained, convalescent states.
The body
- Trembling weakness. The keynote: trembling and prostration from the least exertion — the hands shake, the knees give.
- Bleeding at the slightest touch. Bruises and haemorrhages from the least cause — the relaxed vessels of the proving.
- Hiccups that won't stop. The quoted sign — intractable hiccups of the exhausted and the drunkard's aftermath.
- Hot flushes with exhausting sweat. Flushes that drain — worse for the least heat.
- After hemorrhage and drunkards. The books use it after loss of blood and after alcohol — the two great drains of the era.
- Worse heat and exertion. Warmth and effort deepen the trembling drain.

Where the classical picture comes from
The strongest of the acids proved the weakest of the states — the trembling, draining, bleeding exhaustion. Sulphuric acid became the remedy of the depleted constitution and the intractable hiccup, read beside the industrial chemistry that came to run the world.
The substance in real medicine Pharmacology
What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.
Sulfuric acid is the world's most-produced industrial chemical — batteries, fertilisers, chemistry itself. Its dilute medical career is the old debility pharmacy, retired; its burns are emergency medicine's classic chemical injury; and the 'acid of the lead chamber' belongs to industrial history as much as alchemy. The chemistry is utterly real; the remedy's states are now haematology and rehabilitation's.

| Carbo vegetabilis | Weakness, collapse | Carbo is air-hungry and cold; Sulph-acid trembling and bleeding. |
