What the other books say about Pyrogenium
The same remedy read by a different author. They disagree, and the disagreements are where the remedy becomes recognisable.
- Pyrogenium in Boericke — The concise clinical Materia Medica that most Indian colleges teach from, in full.
- Pyrogenium in Kent — Kent teaching a class, one remedy at a time — fewer remedies, far more on each.
- Pyrogenium in Boger — A compressed key — the generals and the characteristic modalities, with very little narrative.
Search every book at once, take rubrics from Kent and Bönninghausen, and practise on a patient who answers back — free account.
