Evidence Rating System
Every remedy in our database is rated on a scale from 1.0 to 10.0. This rating reflects how strongly the scientific research supports the traditional and claimed uses of that remedy.
The Rating Scale
Multiple high-quality clinical trials, systematic reviews, or meta-analyses support the primary uses. The research is consistent, well-designed, and conducted on humans. These remedies have the strongest scientific backing.
Several clinical trials show positive results, though the research may have some limitations in size, design, or consistency. Traditional use is well-documented and aligns with the research findings.
Some clinical evidence exists, often from smaller studies or preliminary trials. Traditional use provides additional support, and the mechanism of action is reasonably understood. More research would strengthen the case.
Evidence is primarily from traditional use, animal studies, or very preliminary human research. The remedy may be promising, but solid clinical evidence is lacking. Use is based more on historical practice than proven results.
Very little scientific research exists. Claims are largely theoretical, based on limited traditional use, or extrapolated from related compounds. These remedies require significantly more research.
How We Determine Ratings
Our ratings consider multiple factors, weighted by their reliability:
- Number and quality of randomized controlled trials (RCTs)
- Systematic reviews and meta-analyses
- Size and duration of clinical studies
- Consistency of results across different studies
- Quality of study design and methodology
- Documented traditional and historical use
- Understanding of mechanism of action
- Safety profile and adverse event reporting
Important Notes
Ratings are not medical recommendations
A high rating means strong research support, not that a remedy is right for you. Individual responses vary, and you should always consult a healthcare provider.
Low ratings do not mean ineffective
Many remedies with lower ratings simply have not been studied extensively. Traditional use over centuries suggests real benefits, even when clinical trials are lacking.
Ratings are updated regularly
As new research is published, we update our ratings to reflect the current state of evidence. Science evolves, and so do our assessments.
Per-Benefit Evidence Dots
On each remedy page, you will also see evidence dots (1-5) for specific benefits. This shows that while a remedy might have strong overall evidence, the strength varies by use case.
