Sage: is known for its natural antiseptic, preservative and bacteria-killing abilities in meat and the air with burning. Volatile oils (distilled from the blossoms) contain the phenolic flavonoids apigenin, diosmetin, and luteolin, plus volatile oils such as rosmarinic acid, which can be easily absorbed into the body.
The leaf is used to make medicine. 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.
