Agnus castus
Made from the chaste tree's berry — the plant that genuinely regulates female hormones in modern phytomedicine, and the classical remedy of sexual and vital depression.
The whole picture, in one breath
Think of a fire gone out: sexual vitality extinguished — cold, flaccid, indifferent — with a deep, hopeless sadness, a sensation that life has drained away, in a person who once burned bright; often the books add a history of sexual excess or gonorrhoeal trouble. The cold, sad, extinguished remedy: that is Agnus castus.
The substance, in plain words
The chaste tree of the Mediterranean, its peppery berry long eaten by monks to quiet desire — hence the name. The same berry is a genuine modern phytomedicine: standardised extracts of Vitex agnus-castus are studied and prescribed for premenstrual syndrome, cyclical mastalgia and certain hormonal disturbances.
The traditional picture Classical sources
The inner state
- Sexual indifference with sadness. The keynote: complete loss of desire with a deep, quiet melancholy — the fire gone out, mourned.
- Hopelessness about recovery. Despair of ever recovering the lost vitality; gloom about the future.
- Memory weak and nervous. Forgetfulness, poor concentration, nervous prostration accompanying the depletion.
The body
- Cold and flaccid. The keynote: coldness of the parts, relaxed and without power — the books describe the complete absence of response.
- Old gonorrhoeal legacy. The era's association: a history of suppressed or badly treated infection underlying the whole state.
- Spermatorrhoea and weakness. Involuntary losses with utter prostration — the books' chronic male complaint.
- Female coldness. The same extinguished state in women: coldness, relaxation, low desire.
- Scanty emissions with chill. The books record coldness of the body with the sexual losses.
- Worse warmth and at night. Warm rooms and the night deepen the sadness and the coldness.

Where the classical picture comes from
The proving gave the extinguished-fire portrait; the old books applied it to the depleted constitutions of the era's great hidden infections, and to simple exhaustion of the vital fire.
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.
Agnus castus is among herbal medicine's most genuine modern stories: standardised Vitex extracts have real clinical-trial evidence for premenstrual syndrome and cyclical breast pain, working on the pituitary's prolactin regulation — a real, hormonal, documented action. The plant that the monks used to quiet desire is the plant modern phytotherapy uses to regulate the cycle.

|---|---|---|
| Selenium metallicum | Sexual debility | Selenium's is prostatic weakness with involuntary emissions; Agnus' is the extinguished fire with cold and grief. |
| Sepia officinalis | Female indifference | Sepia is the worn-out mother better for dance; Agnus is cold, sad and without response. |
| Conium maculatum | Sexual suppression and glands | Conium's comes with hard glands and turning vertigo; Agnus' with cold and sorrow. |
| Murex purpurea | Female excitement vs depression | Murex is the over-excited opposite pole; Agnus the extinguished one. |
