Frequently Asked Questions
What is Rosemary Leaf?

A typical dose is 1-2g dried leaf daily as tea, or 500-1,000 mg standardized extract daily. Rosemary is FDA-recognized as GRAS at culinary doses. At therapeutic doses, it may interact with blood thinners, seizure medications, and should be avoided in therapeutic amounts during pregnancy.
What does the research say about Rosemary Leaf for memory and cognition?
Human studies have shown that rosemary leaf powder (750 mg) can acutely improve memory speed, and inhalation of rosemary essential oil has been associated with improved cognitive performance and alertness in several small trials. The neuroprotective effects are primarily attributed to carnosic acid and 1,8-cineole, though larger-scale clinical trials are still needed.
