Cobaltum metallicum
Made from cobalt — the blue of the porcelain and the hardener of steel, the essential heart of vitamin B12, and the classical remedy of the low backache.
The whole picture, in one breath
Think of a back that will not hold up: a constant, low backache worse for sitting and lying, the weakness after the emissions of the books, the debility of the exhausted nerve, and the blue metal that sits at the heart of the body's most complex vitamin. The low-backache metal: that is Cobaltum.
The substance, in plain words
Cobalt is the blue metal of porcelain and glass, the hardener of steel — and a genuinely essential element: it sits at the very centre of vitamin B12, the most complex vitamin, without which the body's nerves and blood cannot be made. The proving gave the metal the low-backache portrait.
The traditional picture Classical sources
The inner state
- Anxiety and despondency. The gloom of the chronic backache and debility, worse at night.
- Irritability. Cross from the constant, dragging ache.
- Dullness. Heavy mind with the exhausted, aching frame.
The body
- Low backache, worse sitting and lying. The keynote: the constant lumbar ache worse for sitting and lying, better walking — the quoted modalities.
- Weakness after emissions. The books' association: the prostration and backache following the seminal losses of the chapter.
- Debility of the exhausted nerve. The general depletion and nervous exhaustion of the same shelf.
- Weak, trembling limbs. The books add the weak, trembling legs of the depleted state.
- Worse sitting, lying and exertion. Rest in any posture aggravates the back; motion eases it.
- Better for walking and warmth. Walking about and warmth ease the lumbar ache.

Where the classical picture comes from
The blue metal's proving gave the low-backache portrait; Cobaltum became the classical remedy of the back that will not rest — the metal that hardens steel serving the back that would not hold.
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.
Cobalt is genuinely essential: it sits at the centre of vitamin B12, and B12 deficiency — anaemia and nerve damage — is real, common and treated with the very vitamin the metal anchors. The backache it portrayed is now orthopaedics' and rheumatology's; the metal's modern story is the quiet indispensability of the B12 at its heart.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Aesculus hippocastanum | Low backache | Aesculus' is dry and lame with the purple piles; Cobaltum's is worse sitting and lying, better walking. |
| Kali carbonicum | Backache and weakness | Kali-carb's is stitching at 2 a.m. with the asthma; Cobaltum's the low, constant, posture-worse ache. |
| Selenium metallicum | The emission-linked depletion | Selenium leaks with the involuntary losses; Cobaltum aches in the back after them. |
| Nux vomica | Lumbar, sedentary | Nux' is the irritable sedentary lumbar; Cobaltum' the posture-worse walking-better one. |
