Data & knowledge-graph export
The entire Materia reference is a knowledge graph: body → condition → remedy → compound → study, with every remedy×condition edge carrying an evidence grade and links to the citations behind it. You can download the whole thing as a single JSON file — the same data the site renders, no scraping required.
What's in the file
The graph is a single JSON object with two arrays — nodes and
edges — plus top-level nodeCount, edgeCount,
and a generated timestamp. Every node has an id (the
content-collection slug), a type, and a label.

Node types
| Type | Count | Description |
|---|---|---|
| remedy | 207 | Herbs, supplements, drugs — each with kind, aliases, safety profile |
| condition | 77 | Symptoms/disorders with severity, red flags, body-part links |
| study | 175 | Primary research — design, year, sample size, effect, PMID/DOI |
| compound | 60 | Active constituents with mechanism and biological targets |
| source | 37 | Non-study citations: NCCIH, MedlinePlus, Cochrane, NIH ODS fact sheets |
| bodyPart | 24 | Anatomical regions — the explorer's clickable nodes |
Edge types
| Type | Count | Carries |
|---|---|---|
| remedy-treats-condition | 144 | grade (A–D / insufficient), summary, tradition alignment |
| remedy-cites-study | 182 | viaCondition — which claim the study supports |
| remedy-cites-source | 65 | viaCondition — which claim the source supports |
| remedy-contains-compound | 49 | remedy → active constituent |
| remedy-interacts-with | 18 | severity, mechanism, optional source ref |
| condition-located-at | 47 | condition → body part |
Using the data
The file is plain JSON — load it in Python, R, D3, Gephi, or pipe it into an LLM
context. The schema field (materia-knowledge-graph/v1)
lets you version-check. Every edge's source and target
reference node ids that are stable content-collection slugs.
Grades follow the scale documented on the methodology page: A (strong), B (moderate), C (limited), D (weak), insufficient. Grades are assigned per remedy × condition — a remedy is never globally "good" or "bad."
