Our approach
Every remedy on WikiRemedy has an evidence level based on the quality and quantity of published research. This helps you understand what the science says alongside what the community has experienced.
Multiple large randomised controlled trials (RCTs) or Cochrane systematic reviews consistently support this remedy. This is the gold standard of medical evidence.
At least one well-designed RCT or multiple smaller studies support this remedy. The evidence is meaningful but may have limitations in size or consistency.
Preliminary studies, small trials or observational data suggest potential benefit. The evidence is early and more research is needed before firm conclusions can be drawn.
No published clinical trial evidence supports this remedy for this condition. This does not mean it does not work — it means it has not been formally studied. Community experience is especially valuable here.
Clinical grades
Evidence levels are assigned by WikiRemedy editors based on published literature. Clinical grades (where shown) reference specific guidelines from bodies such as the ESC, AHA or WHO.
