Free homeopathy resources for students

The useful set of free homeopathy resources is smaller than a search engine suggests and better than students fear: the foundational texts of the tradition are public domain, and the serious software vendors publish genuinely usable free tiers. It compiles to a working study library at $0 USD.

1. The public-domain texts

The core curriculum is out of copyright and scanned. Four starters, with the full annotated list on our textbook PDF page:

1. Hahnemann's Organon of Medicine, sixth edition — the primary source.
2. Kent's Repertory of the Homoeopathic Materia Medica — the index the method runs on.
3. Kent's Lectures on Homoeopathic Philosophy — the standard commentary.
4. Allen's Keynotes and Characteristics — the first materia medica layer.

All are hosted by the Internet Archive, a non-profit library; downloading them is lawful because the copyrights have expired.

2. Free software tiers

Two free tiers are substantial enough for coursework. Similia's published Free plan includes classic repertory access, a classic materia medica library, semantic search in the repertory, and up to three new cases and three new analyses per month — and it can be used indefinitely. That covers the weekly paper-case loop from our study guide without payment; students who later need more will find a published student discount. You can start on the free tier at similia.io. Complete Dynamics also publishes a free Browser edition; running both costs nothing and teaches you what software choices actually trade off — the comparison is on our best-software page.

3. Free reference surfaces on this site

The glossary defines the working vocabulary. The practice exam is a free self-test with an answer key, and the learn-repertorization page teaches the central method without assuming any purchase.

What "free" should make you suspicious of

Sites offering free PDF downloads of Synthesis, Murphy's repertory, Vithoulkas, Sankaran, or other modern works are distributing pirated copyrighted material. Beyond the legal exposure, pirated scans are routinely incomplete or corrupted — a poor foundation for memorizing rubric structure. The rule of thumb: pre-1930 texts are usually legitimately free; anything by a living author is not. Our notes-pdf page applies the same rule to study notes.

What to read next

Download the four texts above via the textbook PDF page, then set the weekly structure with the study guide. For paid texts worth adding once budget allows, the book recommendations page ranks the modern authors by curriculum stage — the entire first year of public-domain materials is on your disk, legally; the book list shows what comes after.
