Every “What does it help with?” card carries a coloured badge. It tells you how sure science is — not how good the plant is.
🟢 Scientists are sure — strong evidence
Several good clinical trials in people, usually summarised in a systematic review or accepted by an official body, found the same benefit.
🟡 Scientists think so — some evidence
Human studies show a benefit, but they are small, few, or not always of high quality. More research could change the picture.
🟠 Still being studied — early evidence
Only lab (test-tube) or animal studies so far. Interesting, but we do not know yet whether it works in people.
🔵 Grandma’s wisdom — traditional use
People have used the plant this way for a long time, sometimes recognised by official bodies as “traditional use”, but it has not been proven in clinical studies.
Rules we follow
- A badge describes the evidence for one specific use, not the plant as a whole.
- Food amounts and supplements are different: evidence for a concentrated extract does not mean eating more of the food does the same.
- When sources disagree, we show both views and choose the more careful badge.
- Safety information is never downgraded because evidence is weak — a single serious report can be enough for a warning.
