1,056 plants · 64,061 graded relationships
Every claim in our knowledge graph carries the grade of evidence behind it — from traditional use through laboratory work to clinical trials. Most herbal writing blurs that line. We draw it.
Each of these is a live corner of the same graph. Open one and follow it as far as the evidence goes.

64%
Nearly two thirds of what is written about herbs is traditional use with no science reviewed. It isn't worthless — but it isn't evidence, and you deserve to know which you're reading.
141
Herbs rated "do not self-administer" are hidden by default everywhere on this site. You can ask to see them. We won't volunteer them.
121
Every relationship traces back to a citation you can look up — Commission E, WHO monographs, published trials. No "studies show".
Search a plant, a symptom or an action and follow the connections outward. The Atlas is the whole corpus in one view — 734 conditions have enough behind them to stand on their own.

The Atlas is the evidence. This is what we do with it for you.
A few questions about your lifestyle, constitution and health history. Not a quiz for its own sake — it's what makes the rest specific to you rather than generic.
Every recommendation comes out of the same evidence graph you can explore here, so you can always follow a suggestion back to the studies and sources behind it.
Preparations, amounts and timings matched to your goals — with the cautions and interactions surfaced, not buried. Practitioner support when you want a person in the loop.
We don't write herbal claims. We re-model what published pharmacological reference works already record, keep the citation attached, and show you the grade.

Every relationship extracted from this work keeps its original citation codes, resolved to 121 named references you can look up.
Editorial content is reviewed by The Sarv Health Team. The extraction pipeline is re-runnable and checked against the source works, and we publish how we work.
