Acidum salicylicum
Made from salicylic acid — the willow-bark chemistry that became aspirin, the world's most-used drug, and the classical remedy of rheumatism with ringing ears.
The whole picture, in one breath
Think of rheumatism with deafness: wandering joint pains with sudden deafness or roaring in the ears, profuse sweating, vertigo, and the whole picture echoing the drug's own toxicology — because the drug and the remedy share one molecule's history. Rheumatism with ringing ears: that is Salicylic acid.
The substance, in plain words
Salicylic acid is the willow-bark chemistry that acetylated into aspirin in 1897 — the most-used drug in human history, antiplatelet, analgesic, antipyretic. Its own overdose — tinnitus, deafness, sweating, vertigo — is 'salicylism,' and the proving wrote the same portrait: rheumatism, ears, sweat.
The traditional picture Classical sources
The inner state
- Dullness and confusion. Foggy, confused, worse with the vertigo; delirium in fever states.
- Anxiety. Worry with the ear-symptoms and the wandering pains.
- Irritability. Cross, worse from noise — which the ears already ring with.
The body
- Rheumatism with ear involvement. The keynote: wandering articular pains with sudden deafness or roaring tinnitus — the salicylate signature.
- Profuse sweating. Drenching sweat with the pains and the fever.
- Vertigo. Whirling vertigo, worse rising and moving.
- Worse motion and night. The pains wander and worsen at night; motion aggravates the vertigo.
- Hot dry skin alternating with sweat. The skin burns dry, then sweats profusely — the febrifuge legacy.
- Better for rest. Stillness, quiet and warmth of the bed
Modalities (worse and better factors)
| Worse from ⬇ | Better from ⬇ |
|---|---|
| motion; night; cold damp; noise. | rest; quiet; warmth. |
Where it acts (organ affinities)
Joints (rheumatic wandering), ears and hearing, skin and sweat, head.
Where the classical picture comes from
The willow chemistry's toxicology — salicylism's ringing, deafness, sweating — wrote the proving before the drug existed to cause it; the remedy's rheumatism-ear portrait is a prophecy of aspirin's side-effect profile, decades early.
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.
Salicylic acid's family is the greatest in over-the-counter medicine: aspirin — acetylsalicylic acid — prevents heart attacks and strokes at one dose, relieves pain and fever at another, and its precursor chemistry still treats warts and acne in topical form. Salicylate ototoxicity — the very tinnitus of the portrait — is taught in every pharmacology course. The molecule is medicine itself.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| China officinalis | Ringing ears, weakness | China rings and bloats after loss of fluids; Sal-acid rings with rheumatism and sweat. |
| Rhus toxicodendron | Rheumatic pains | Rhus is damp-stiffness better motion; Sal-acid is wandering with the ear signature. |
| Arsenicum album | Restlessness, prostration | Arsenicum is anxious, chilly, midnight; Sal-acid is sweaty, vertiginous, ringing. |
| Nux vomica | Headaches, irritability | Nux is stimulant-born and spasmodic; Sal-acid is rheumatic and roaring. |
