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