Materia — The whole body,
evidence-graded.

Materia is an anatomy-led reference for remedies. A layered, clickable human body leads into a knowledge graph linking body, condition, remedy, compound, and study. Curated efficacy claims carry an evidence grade and citation; reference-only entries are clearly separated. It is ad-free and not medical advice.

Yes, Materia is completely free and ad-free. It is a static reference site with no subscription, no account, and no advertising. All content is publicly accessible to anyone, with nothing gated behind a paywall or sign-up.

Each remedy is assigned an evidence grade based on the quality and quantity of cited studies. Grades reflect the strength of clinical research, ranging from meta-analyses down to traditional use. The methodology page explains the full grading system in detail.

Materia currently maps 207 remedy entries across 24 body parts and 77 conditions. Of those remedies, 91 have curated evidence content; the remaining drug and herb entries are reference scaffolds without efficacy claims. The 553-page baseline is published and intentionally paused rather than continuously expanded.
