Stannum metallicum
Made from tin — the humble canning metal whose organotin cousins are modern toxicology, and the classical remedy of weakness in the chest.
The whole picture, in one breath
Think of a chest too weak to cough: a hollow, empty weakness of the lungs, short breath, a cough that ends in a sweetish taste of phlegm, and arms that feel weak all the way to the fingers — worse for talking, singing, using the voice. Chest weakness, sweetish phlegm, voice-worse: that is Stannum.
The substance, in plain words
Tin is the soft canning metal of everyday life — inert in the body in bulk, but its organotin compounds are potent modern poisons. The proving gave the library's classic portrait of respiratory weakness, where the chest cannot muster the effort to clear itself.
The traditional picture Classical sources
The inner state
- Sadness and despondency. Low-spirited, weepy, worse in the morning with the weakness.
- Anxiety about health. Fear the chest will never strengthen.
- Irritability. Cross after the least exertion, which exhausts.
The body
- Weakness of the chest. The keynote: a sensation of emptiness and weakness in the chest; cannot cough deeply for want of power.
- Cough with sweetish taste. The expectoration tastes sweetish — the quoted confirming sign of the books.
- Worse for using the voice. Talking, singing and reading aloud bring on the cough and weakness.
- Weakness down the arms. Weakness from chest to shoulders and fingers; arms feel heavy and useless.
- Better for expectoration. Relief comes only when the mucus is finally raised.
- Worse lying and motion. Lying flat and exertion aggravate the breath; must sit with support.
Modalities (worse and better factors)
| Worse from ⬇ | Better from ⬇ |
|---|---|
| using the voice; lying down; exertion; talking and singing. | expectoration; sitting with support; rest of the voice. |
Where it acts (organ affinities)
Lungs and respiration, voice and larynx, arms (weakness), general vitality.
Where the classical picture comes from
The soft metal's proving gave the soft portrait — weakness, emptiness, sweet taste. Clinically Stannum served the chronic bronchitics whose chests had run out of power, and whose sweetish phlegm the old books record precisely.
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.
Tin itself is nearly inert in the body; its real pharmacology belongs to the organotins — potent industrial biocides and textbook neurotoxins. The metal's everyday story (canning, solder) and its toxic cousins frame the remedy modestly: the chest weakness it portrayed is now respiratory physiotherapy and medicine's territory.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Phosphorus | Chest weakness, cough | Phosphorus is thirsty, bleeding and twilight-worse; Stannum is sweet-phlegmed and voice-worse. |
| Causticum | Hoarseness, weakness | Causticum's voice is morning-hoarse with injustice weeping; Stannum's is weak and sweet. |
| Kali carbonicum | Asthma, stitching | Kali-carb is 2 a.m., stitching and backachy; Stannum is the all-day hollow weakness. |
| Senega officinalis | Chest soreness, tough mucus | Senega rattles tough mucus with sore chest walls; Stannum simply hasn't the strength. |
