Stigmata maydis
Made from corn silk — the golden threads of the maize cob, a genuine soothing diuretic of the old dispensaries, and the classical remedy of gravel and irritated bladder.
The whole picture, in one breath
Think of the irritated, sediment-laden bladder: constant burning and urging, gravelly sediment of red or white sand, urine that cannot be held on the least excitement, and a backache with the whole picture. The sandy, excitable bladder: that is corn silk.
The substance, in plain words
Corn silk — the stigmas of the maize cob — was an official soothing diuretic of the old pharmacopoeias, prescribed for gravel and bladder irritation. Its potassium-rich, mucilaginous chemistry is genuinely demulcent-diuretic; the proving gave the classical sandy-urine portrait.
The traditional picture Classical sources
The inner state
- Anxiety with the urging. Fretful, worse as the sediment appears; dread of excitement.
- Irritability. Cross, worse in damp weather.
- Despondency. Gloomy in the recurrent, gravelly states.
The body
- Gravelly sediment. The keynote: red or white sand in the urine, season after season.
- Burning and urging. Constant burning, urging and difficulty holding the water on excitement.
- Urine excitable. The books note it is passed involuntarily on the slightest emotion — the excitable bladder.
- Backache with it. A dull lumbar ache over the kidneys accompanying the bladder picture.
- Worse damp cold. Wet weather restarts the sediment and the burning.
- Better for warmth Warmth, rest and the free passage of sand bring ease.

Where it acts (organ affinities)
Bladder and urethra, kidneys, urine (sediment), back.
Where the classical picture comes from
The official diuretic's career — the maize cob's threads in the apothecary jar — gave the proving its frame; the remedy became the classical portrait of the sandy, excitable, irritated bladder.
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.
Corn silk was a genuine, official soothing diuretic — its potassium and mucilage chemistry really does soothe and drain, and it remains a respectable herbal urinary remedy in several traditions. The gravel and irritation it managed are now urinalysis, dietary prevention and modern urology; the silk's chemistry is real, its career modest and honest.
Look-alikes (how the classical authors told it apart)

|---|---|---|
| Hydrangea arborescens | Gravel constitution | Hydrangea is the constitutional gravel remedy; Stigmata the sandy, excitable, irritated bladder. |
| Ocimum canum | Stone colic | Ocimum is the right-sided colic; Stigmata the chronic sandy irritation. |
| Cantharis vesicatoria | Burning urging | Cantharis scalds and screams; Stigmata smoulders with sand. |
| Equisetum hyemale | Bladder irritation | Equisetum's is the tender, touch-me-not bladder; Stigmata's the sandy, excitable one. |
