Free materia medica online
The classical corpus — Boericke, Kent, Clarke, Hering, Hahnemann — is out of copyright and legitimately available in full text online. Modern platform free tiers add unified search across that corpus. A third category of "free" sites republishes the same public-domain material stripped of attribution and reframed as remedy-for-ailment advice the original texts never offered.
What is genuinely free, by category
| Category | What you get | The catch |
|---|---|---|
| Public-domain full texts (Médi-T, Internet Archive) | Complete Boericke, Clarke, Kent, Hering, Hahnemann as hypertext or scans | Per-book search only; no cross-corpus collation; dated interfaces |
| Platform free tiers (Similia Free, Complete Dynamics browser) | Classic library with unified search; on Similia, semantic search and the classic repertory included | Account required; modern licensed authors and advanced features sit on paid tiers |
| Aggregator/advice sites | The same public-domain text, republished | Attribution often stripped; framing drifts from literature to implied prescribing |
The first two rows are honest deals. The third is where most newcomer search traffic lands.
The aggregator problem
A large share of "free materia medica online" results are sites that repackage Boericke's 1927 text without naming the edition, interleave it with condition-targeted headings, and surround it with supplement commerce. Two things are lost in that repackaging. Provenance: the reader can no longer tell Boericke's keynote from the site's own addition, which destroys the source discipline that makes the literature studiable. And framing: the classical texts record proving symptoms and practitioner observations, but a page reorganised as "remedies for X" converts description into recommendation — a conflation that distorts how the literature should be read and applied.
Practical rule: if a free site does not name author and edition for every passage, read the same text at a source that does.
The honest free stack, assembled
A complete no-cost study setup takes ten minutes to put together.
For assigned or systematic reading, Médi-T's hypertext classics are clean transcriptions navigable by remedy, with the Internet Archive as the fallback for the deep shelf — Hering's ten volumes and the pre-1900 works.
For lookup and cross-author search, use a platform free tier. The Similia free repertory carries the classic repertory, the classic materia medica library, semantic search across both, and up to three new cases and three new analyses per month — enough for study use, with no card required and free accounts usable indefinitely. Complete Dynamics' browser edition covers similar ground at the classic layer.
For further reading by remedy, work through the portrait pages — Arsenicum album and Belladonna are good starting points, or the materia medica overview for the genre as a whole.
Where the free stack ends
The modern interpretive literature is in copyright and licensed per platform. Murphy, Vermeulen, Mangialavori, Scholten, and the contemporary synthesis repertories appear on Similia as Pro editions and one-time purchases; equivalents on RadarOpus and Complete Dynamics are likewise paid. Any site offering those texts free without a valid licence is infringing, and the scanned copies that circulate are usually incomplete editions — a bad trade for a literature whose value depends on textual accuracy.
What free covers, and what it does not
On tooling, the free options above are not crippled demos. The public-domain corpus is the same corpus the paid suites license, and the platform free tiers use the same underlying search technology as their Pro plans. A student can study seriously for years without spending anything.
What free does not cover is the modern interpretive layer: the post-1990 authors, the updated synthesis repertories, and the licensed contemporary provings. Those require paid platform plans or individual purchases, regardless of which platform you choose.
