Sage (Salvia officinalis) is a pungent herb from the mint family. People use the leaf for memory, focus, and mood. The plant contains antioxidants and natural compounds including thujone, cineole, and rosmarinic acid. Supplements come as dried leaf, liquid extract, or standardized pills.
Sage is often taken to sharpen concentration during study or to support clear thinking with age. A warm cup of sage tea or a throat spray can also soothe a scratchy throat or calm mild digestive discomfort.
Standardized extracts are typically taken once or twice daily. Doses vary by form. Do not use sage if you are pregnant, breastfeeding, or have a seizure disorder. The herb may alter the effect of blood thinners, diabetes drugs, and anticonvulsants.
