Omnia SanaAbout Us
Where plant tradition meets science
Omnia Sana is an evidence-based herbalism resource that connects traditional plant knowledge with peer-reviewed science - so you can see what the research actually says, and use it responsibly.
What we do
Every plant we cover is documented in a structured database where each claim is tied to scientific literature and given a transparent evidence score. Instead of folklore presented as fact, you get sourced, traceable information you can verify yourself.
On top of that database we build free, referenced resources and a growing suite of interactive tools:
- Materia Medica - in-depth, referenced profiles of medicinal plants.
- Symptom-to-Plant Lookup - find the plants linked to a symptom, ranked by strength of evidence.
- Browse by Plant - see every condition a plant is used for, then open its full profile with studies and safety.
- Two-Plant Comparison - put two plants side by side across constituents, actions, uses and safety.
- Knowledge Finder - search the underlying citations and studies directly.
- Herb-Drug Interaction Checker - class-level safety signals for a herb taken alongside a type of medication.
- Herb-Herb Combinations - the synergies and cautions when two herbs are paired.
- Dangerous Lookalikes - the toxic plants a medicinal one can be mistaken for, and how to tell them apart.
- Harvest Calendar - when each plant part is traditionally gathered, with the field signs that mark readiness.
- Tincture & Extract Yield Calculator - plan a single-herb preparation with accurate ratios.
- Multi-Herb Formula Calculator - build a multi-ingredient tincture or glycerite and blend its strength.
- Quick Plant Monograph Builder - generate a printable, fully-sourced fact sheet for any plant.
- Plant-Name Dictionary - the common names of each plant across dozens of languages.
- Plant Sighting Map - a community map of real-world plant sightings.
How this site is built
There are two kinds of page here, and it is worth being clear about which is which.
Written pages - the articles, the field-identification guides and this page - are researched and written by us.
Generated pages - plant profiles, monographs, comparisons, the name dictionary and the reference library - are assembled automatically from our plant database. The database is the actual work; those pages are a view onto it. Every figure and citation on them traces back to a record we entered and reviewed.
We use software, including AI tools, to help find candidate sources, pull structured data out of them and check the database for inconsistencies. The judgement calls stay with us: which sources count, how strong the evidence is, and what gets published.
Why we built Omnia Sana
Information about medicinal plants is everywhere, but most of it is unsourced, contradictory, or commercially motivated. We built Omnia Sana to fix that: one place where botanical tradition and modern research meet, every statement is cited, and the strength of the evidence is shown openly rather than overstated.
Our approach to evidence
Each plant claim is graded on a transparent evidence scale derived from the type and quality of the supporting studies - from traditional use through to controlled clinical trials. Sources are linked so you can read the original research, and we update profiles as new studies are published.
Some associations on this site are inferred: the research supports a plant’s general pharmacological action rather than its use for one specific condition. Where that is the case we say so on the page rather than quietly rounding it up into direct evidence.
Corrections
If you find an error, please tell us at contact@omniasana.bio. We would much rather be corrected than be wrong, and we will say what changed. Because every page is generated from the same underlying records, fixing a claim at the source corrects it everywhere it appears.

Frequently asked questions
Is Omnia Sana medical advice?
No. Omnia Sana is an educational resource. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider before using any plant medicinally, especially alongside other medications.
Who writes this site?
Two people, named and described under Who we are at the foot of this page. Neither of us holds a medical qualification, which is why every claim is cited and graded rather than asserted.
Where does your information come from?
From peer-reviewed scientific literature and documented traditional use. Every claim in our database is linked to its sources, which you can explore through the Knowledge Finder.
How can I support your work?
Omnia Sana is independent. You can help us keep expanding the database and our research by visiting our Support Our Research page, or by getting in touch.
Who we are
Omnia Sana is built by two people. We think you should know who they are before you decide how much weight to give anything on this site.
Founder & Editor
Rihards Serafimovičs
MSc Geography & Earth Sciences
Research, data analysis and the engineering behind the database and the tools. The earth-sciences training is what shapes how this site handles habitat, distribution, seasonality and field identification - the parts of herbalism that are really applied ecology. LinkedIn
Founder & Editor
Elza Roberta Sprikute
B.A. Classical Philology
Editorial and writing. A background in classical philology is what makes the historical half of this subject workable: reading older herbal sources closer to their originals, handling botanical Latin properly, and the plant-name work that spans 34 languages. Instagram
Neither of our degrees is a medical, pharmacological or clinical qualification, and we do not present them as one. We have no medical reviewer on the team at present. That is precisely why the site is built the way it is: instead of asking you to trust our judgement, every claim carries its citation, and the strength of the evidence behind it is shown openly - including when that evidence is weak.
