The name Sage is derived from the Latin word salvere meaning ‘to save’. The herb is a member of the mint family and has many of the healing properties of its sisters.
Sage is a native of the Mediterranean area. It is largely cultivated in Yugoslavia, Italy, Albania, Turkey, Portugal, Spain, Cyprus, England, Canada and USA. In India, it is sparingly cultivated in and around Jammu.
The volatile oils and phytochemicals in sage include thujone, rosmarinic acid, camphor, tannin, flavonoid, estrogenic compounds and cineole. Like other commonly used dried herbs in the kitchen, sage is used for seasoning fish, meat, salads, sandwiches etc.
The popularity of sage can be easily reflected from the fact that in the ancient times, the Chinese used to exchange three cases of tea leaves with the Dutch, for a single case of sage leaves. Sage is a boon in conditions like indigestion, gas, depression and menopausal problems, owing to the nutrients in it. The sage leaf is a great source of nutrients, just like other vegetables.
