This review found that rosmarinic acid—a compound from plants like rosemary and mint—gets broken down by your gut bacteria and processed by your body through the kidneys. Studies suggest it may help with skin conditions, allergies, and inflammation, though most evidence comes from lab tests rather than large human trials. The research flagged that we need longer-term studies to really understand how well it works when used regularly.

This is a review article that analyzed existing pharmacokinetic (how your body processes) and clinical studies on rosmarinic acid, including both animal and human research. The authors summarized what's known about how the compound enters, moves through, and leaves the body.
