Sage has one of the longest histories of use of any culinary or medicinal herb. Ancient Egyptians used it as a fertility drug (Bown, 1995). In the first century C.E. Greek physician Dioscorides reported that the aqueous decoction of sage stopped bleeding of wounds and cleaned ulcers and sores. He also recommended sage juice in warm water for hoarseness and coughs. It was used by herbalists externally to treat sprains, swelling, ulcers, and bleeding. Internally, a tea made from sage leaves has had a long history of use to treat sore throats and coughs; often by gargling. It was also used by herbalists for rheumatism, excessive menstrual bleeding, and to dry up a mother's milk when nursing was stopped. It was particularly noted for strengthening the nervous system, improving memory, and sharpening the senses.
Sage is used for digestive problems, including loss of appetite, gas (flatulence), stomach pain (gastritis), diarrhea, bloating, and heartburn. It is also used for reducing overproduction of perspiration and saliva; and for depression, memory loss, and Alzheimer's disease.
Women use sage for painful menstrual periods, to correct excessive milk flow during nursing, and to reduce hot flashes during menopause.
Sage is applied directly to the skin for cold sores; gum disease (gingivitis); sore mouth, throat or tongue; and swollen, painful nasal passages.
Some people inhale sage for asthma.
