What the other books say about Phosphorus
The same remedy read by a different author. They disagree, and the disagreements are where the remedy becomes recognisable.
- Phosphorus in Boericke — The concise clinical Materia Medica that most Indian colleges teach from, in full.
- Phosphorus in Farrington — Lectures that teach remedies in families, by comparing them with each other.
- Phosphorus in Kent — Kent teaching a class, one remedy at a time — fewer remedies, far more on each.
- Phosphorus 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.
