Asterias rubens
Made from the common starfish — the five-armed echinoderm of the northern seas, and the classical remedy of the breast and the left side.
The whole picture, in one breath
Think of a left-sided trouble around the breast: a breast that hardens and ulcerates in the old books' cancer chapter, axillary glands swollen, numbness and tingling of the left side, the books' great starfish remedy of the female breast and the left arm. The left-breast starfish: that is Asterias.
The substance, in plain words
The common starfish is the five-armed echinoderm of the northern Atlantic, its body a skeleton of calcium plates and its chemistry rich in genuine saponins — the echinoderm's own defensive molecules, studied in marine pharmacology. The proving gave the remedy its left-sided, breast-centred portrait.
The traditional picture Classical sources
The inner state
- Anxiety and fear. Fear of the breast trouble, of the hardening, worse at night.
- Irritability. Cross, worse from contradiction; the books note a nervous temperament.
- Despondency. Gloomy in the chronic, ulcerating states.
The body
- Breast hardening and ulceration. The keynote: the breast that hardens, then ulcerates — the books' cancer-chapter use, with the axillary glands swollen.
- Left-sidedness. The left breast, the left arm — the starfish's quoted side.
- Numbness and tingling. Numb, tingling, crawling sensations of the left side — the marine saponin chemistry in the portrait.
- Worse cold damp and night. Wet weather and night deepen the pains and the hardening.
- Axillary glands. The armpit glands swell and harden with the breast.
- Better for rest and warmth. Rest and warmth ease the left-sided pains.

Where it acts (organ affinities)
Breast and axillary glands, left side, skin, nerves (tingling).
Where the classical picture comes from
The marine starfish's proving gave the left-breast portrait; Asterias became the classical remedy of the hardening, ulcerating breast of the old cancer chapter, read beside the echinoderm's genuine saponin chemistry.
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.
Echinoderm saponins — including the starfish's — are a genuine subject of marine pharmacology, studied for antimicrobial and anti-tumour activity; the creatures defend themselves with real chemistry. The breast states it portrayed are now breast-clinic medicine: mammography, biopsy, surgery and oncology's real, improving treatments.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Conium maculatum | Hard breasts, vertigo | Conium's hardens with the turning-head vertigo; Asterias' with the left side and the numbness. |
| Phytolacca decandra | Radiating breast | Phytolacca's breast radiates and is purple-throated; Asterias' is left-sided and numb. |
| Carcinosin | Cancer-linked constitution | Carcinosin is the mole-marked constitution; Asterias the left-breast remedy of the chapter. |
| Bellis perennis | Bruised breasts | Bellis' are the bruised, deep-sore breasts; Asterias' the hardening left one. |
