Research index
Every published paper cited anywhere in this encyclopedia, listed once, with its PubMed identifier and DOI, and cross-referenced to the herbs and formulations it concerns. 3507 papers across 478 subjects, 1861 to 2026.
This exists because the inverse view is useful and nobody publishes it: not "what does the literature say about this herb", but "what literature exists, and which herbs does each paper concern". Free to download and reuse under CC BY 4.0.

By study type
Grouped by what kind of study it is, strongest first. This ordering is about the design of the study, not about whether the herb works. A large body of laboratory work is not weak evidence of an effect in people; it is not evidence of an effect in people at all.
- Systematic reviews and meta-analyses
158 papers. Pooled analyses of multiple studies. The strongest form of evidence listed here.
- Randomised controlled trials
105 papers. Controlled trials in people.
- Other clinical studies and reviews
1171 papers. Individual clinical studies, observational work and narrative reviews.
- Laboratory and animal studies
2073 papers. Cell-culture and animal work. Does not show an effect in people.

What this is not
A listing here means a paper exists and concerns the subject. It does not mean the paper found a benefit, that the finding replicated, or that the herb works. Several entries report null or negative results, and many are laboratory studies with no human data at all. Read the paper.
Coverage is limited to what PubMed indexes. Much of the classical formulation literature is published in Indian journals that PubMed does not carry, so a thin entry for a churna or a ghrita reflects the reach of the index rather than the state of the evidence.
