The Latin name for sage, salvia, means to heal. Modern evidence supports its effects as an anhidrotic, antibiotic, antifungal, astringent, antispasmodic, estrogenic, hypoglycemic, and tonic. Sage extract is used in connection with sprains, swelling, ulcers, and bleeding; for sore throats and coughs. Herbalists have also used this herb for rheumatism, menstrual bleeding, strengthening the nervous system, improving memory, and sharpening senses. Sage extract is recommended for fever. Modern research has demonstrated that sage reduces perspiration by as much as 50 percent. Sage is also an active ingredient in some natural mouthwashes because its tannins are thought to help kill the bacteria that cause gingivitis. Sage extract has traditionally been used to treat canker sores, bleeding gums, sore throat, tonsillitis, and laryngitis.
