Sage:
Botanical name: salvia officinalis
Use: Sage has one of the longest histories of use of any culinary or medicinal herb. Ancient Egyptians used it as a fertility drug. 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. 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.
