Equisetum hyemale
Made from horsetail — the silica-laden rush of riverbanks, a genuine diuretic-astringent herb, and the classical remedy of the tender, irritable bladder.
The whole picture, in one breath
Think of a bladder that cannot bear its own work: constant urging with intolerable tenderness at the neck of the bladder, burning and cutting as the urine passes, pain as if from a great blow across the back, and — in children — bed-wetting without obvious cause. The tender irritable bladder: that is Equisetum.
The substance, in plain words
Horsetail is the jointed silica rush of riverbanks, its stems packed with silicic acid — the same family as Silicea's chemistry. It is a genuine diuretic-astringent herb of the old dispensaries, and the proving gave the classical bladder-tenderness portrait.
The traditional picture Classical sources
The inner state
- Anxiety with the urging. Fretful, worse at night with the constant desire.
- Irritability. Cross from the unrelenting discomfort.
- Despondency. Gloomy in the chronic, recurrent cystitis states.
The body
- Tenderness of the bladder neck. The keynote: intolerable tenderness at the neck of the bladder, as if it could not bear to be used.
- Constant urging with pain. Urging, burning, cutting; the urine scalds as it leaves.
- Pain as from a blow across the back. The quoted sensation — as if the back had been struck.
- Bed-wetting in children. The books use it for enuresis without organic cause — the tender, irritable bladder of childhood.
- Worse touch and pressure. The bladder region cannot bear touch; jarring aggravates.
- Better for lying Rest and warmth ease the tenderness.

Where it acts (organ affinities)
Bladder (neck and mucosa), urinary function, back, children's enuresis.
Where the classical picture comes from
The dispensary diuretic's astringent chemistry gave the proving its frame; the bladder-tenderness keynote — 'cannot bear to be used' — made Equisetum the irritable-bladder remedy of the classical books, and the child's bed-wetting its gentler territory.
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.
Horsetail's silica chemistry is genuine — the plant absorbs and concentrates silicic acid, and its diuretic-astringent action is real, though its safety is debated because of trace nicotine-like alkaloids. The cystitis it portrayed is today managed with urinalysis and antibiotics; the bed-wetting with paediatric assessment — the territory is modern medicine's, the chemistry real.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Cantharis vesicatoria | Burning urinary states | Cantharis scalds with constant urging; Equisetum is tender and cannot bear touch. |
| Mercurius corrosivus | Urinary tenesmus | Merc-cor's is the relentless tenesmus and mucus; Equisetum the tenderness. |
| Kreosotum | Bed-wetting | Kreosote's wetting is in deep sleep with acrid discharges; Equisetum's from the tender bladder. |
| Benzoicum acidum | Strong-smelling urine | Benzoic's is the offensive, gouty urine; Equisetum's the tender bladder. |
