Sage is an herb with oblong gray-green leaves which are used in cooking and herbal medicine. The herb has a pungent, mildly astringent, slightly bitter to peppery flavor which accents many foods including roasts, soups, savory sauces, and stuffing. The herb is also used in extracts and teas to improve digestive problems and to help regulate the menstrual cycle. Sage extracts and concentrated sage should be avoided by pregnant women, as the herb stimulates uterine contractions, and by people prone to convulsions and seizures, as sage contains a compound which can cause convulsions. Studies have also shown that sage has a compound which may enhance memory, although large amounts of it would need to be consumed.

There are hundreds of species of sage in the Salvia genus, but the version most frequently used in cooking is Salvia officinalis. This variety of sage is native to Southern and Eastern Europe, and has been included in regional European cuisine for centuries. In addition, sage is widely cultivated in other parts of the world as a seasoning, and is readily available in dried form at most markets. Stores with a selection of fresh culinary herbs usually also carry fresh sage, although sage is one of the few culinary herbs which actually has a more intense and concentrated flavor after drying. If you purchase dried sage, keep it in a cool dark place in an airtight container to keep it flavorful.

Whole sage leaves can be included in foods to add flavor and texture, or the herb can be used in a crushed or powdered form. In either case, sage should be used with discretion, because the flavor can be intense, and a mildly flavored dish can be overwhelmed by the bitterness in sage, which varies depending on the season and what variety is being eaten. Sage is especially excellent with fatty cuts of meat, and can be included with roasts, pan fried, barbecued, or used as a rub along with a mixture of other spices.

Sage is relatively easy to grow, and will thrive in most environments as long as it is in sunny, well drained soil. Sage prefers to dry out completely before it is watered again, and the low bush will produce purple flowers in the height of summer. Because sage is a perennial, it will return year after year, although it may start to look slightly weedy in the fall; sage can be trimmed back closer to the ground for winter when gardeners winterize the garden.
