Rosemary and Cognitive Function
Rosemary has traditional and experimental interest in cognition, but product claims should match the evidence.

What it is
Rosemary (Salvia rosmarinus) is used as a culinary herb and has also been studied in aroma, extract and supplement contexts.
What the evidence suggests
Different forms of exposure are not interchangeable. An aroma study cannot validate an oral capsule dose, and vice versa.
What to check on a supplement label
Treat rosemary as an ingredient with research interest rather than a proven treatment for memory problems.
- Exact daily amount
- Extract or compound form
- Any standardization details
- Other ingredients with overlapping effects
How to interpret claims
The strongest consumer rule is to match the claim to the study. Evidence about one extract, one dose or one population should not be generalized to every product bearing the ingredient name.
