It is native to the Balkans and the Mediterranean but has grown widely elsewhere as a garden and pot herb. It prefers dry chalky soils in sunny areas but will thrive in a rich loamy soil with good drainage. 
The primary biologically active component of common sage appears to be its essential oil, which chiefly contain ketones; α-thujone, and β-thujone. In addition, sage leaf contains numerous other compounds, including cineol, borneol, tannic acid; bitter substances like cornsole and cornsolic acid; fumaric, chlorogenic, caffeic and nicotinic acids; nicotinamide; flavones; flavone glycosides and estrogenic substances. 
Sage tea or infusion of sage is a valuable agent in the delirium of fevers and in the nervous excitement frequently accompanying brain and nervous diseases. It has a considerable reputation as a remedy, given in small and often-repeated doses. 
The active compounds are known to have counter-irritant, rubefacient, anti-inflammatory, antiallergic, antifungal, and antiseptic properties. 
Apart from medical uses of Salvia officinalis is also used for cosmetic uses due to its.
Antioxidant and free radical scavenging activity.

| Dental Applications of Salvia Officinalis|| |
Cicatrizant and bactericidal
(Ulcers and wounds) To heal the ulcers, cuts, scratches, chafing, or any wounds, supporting the cicatrization and preventing wounds to become infected.
- Compresses with the maceration of dry leaves in white wine or the green plant applied directly on the wound.
- For mouth ulcers, dental caries, or gingivitis infusion of half a tablespoon of dried herb for mouthwash. It is very useful for herpes treatment.
- Because of its bactericidal and cicatrizant properties, it can prevent scabies sores to become infected. (Wash the affected areas with the infusion of the dried plant.) This preparation can be use to treat eczema.
With the wine maceration previously mentioned, we can rinse our mouth in order to fortify our gums. We can also use the green leaves to rub our teeth and gums to the same aim. 
Dr. Kermanshah et al.,  performed an in-vitro study in to evaluate the cariostatic effect of hydroalcoholic extract of Salvia officinalis and Achillea millefolium. The antibacterial activity of these two extracts against Streptococcus mutans, Lactobacillus rhamnosus, and Actinomyces viscosus were evaluated through broth macrodilution method. The Minimum Inhibitory Concentration (MIC) of Salvia officinalis and Achillea millefolium for S. mutans were 6.25 and 50 μg, respectively. The differences between the two extracts were statistically significant. Salvia officinalis greater inhibitory effect on growth of all three bacteria. Both extracts had bactericidal effect in the considered concentration range.
Delamare et al.,  carried out a similar study on antibacterial activity of the essential oils of Salvia officinalis L. and Salvia triloba L. cultivated in South Brazil. The major constituents of the oil of S. officinalis were α-thujone, 1,8-cineole, camphor, borneol, and β-pinene, whereas those of S. triloba were α-thujone, 1,8-cineole, camphor, and β-caryophyllene. The essential oils of both species exhibited remarkable bacteriostatic and bactericidal activities against Bacillus cereus, Bacillus megatherium, Bacillus subtilis, Aeromonas hydrophila, Aeromonas sobria, and Klebsiella oxytoca. Moreover, the essential oil of S. triloba efficiently inhibited the growth of Staphylococcus aureus. S. aureus, and A. hydrophila growth were drastically reduced even in the presence of 0.05 mg/mL of the essential oil of S. triloba.
Boonyanit Thaweboon proved that the anticandidal activities of Salvia officinalis L. (S. officinalis) is essential oil against Candida albicans and the inhibitory effects on the adhesion of C. albicans to polymethyl methacrylate (PMMA) resin surface. 
Disc diffusion method was first used to test the anticandidal activities of the S. officinalis. Then the minimal inhibitory concentration (MIC) and minimal lethal concentration (MLC) were determined by modified membrane method. 
The result obtained was that S. officinalis L. essential oil exhibited anticandidal activity against all strains of C. albicans with inhibition zone ranging from 40.5 to 19.5 mm. So, it is concluded that S. officinalis L. essential oil exhibited anticandidal activities against C. albicans and had inhibitory effects on the adhesion of the cells to PMMA resin surface. With further testing and development, S. officinalis essential oil may be used as an antifungal denture cleanser to prevent candidal adhesion and thus reduce the risk of candida-associated denture stomatitis. 
Joanne Smullen  performed a study to prove that plant extracts can inhibit formation of dental plaque. The ability of extracts of Rosmarinus officianalis L., Salvia officianalis L., unfermented cocoa, red grape seed, and green tea to inhibit plaque bacteria, glucosyltransferase activity, glucan, and plaque formation in an in vitro model using bovine teeth was examined.
Standard susceptibility agar dilution technique was used for this. They arrived at a conclusion that the plant extracts, particularly those from R. officianalis L. and S. officianalis L., inhibited glucosyl tranferase activity, glucan production, and plaque formation in vitro. The results suggest that the extracts of R. officianalis L. and S. officianalis L. may be useful as antiplaque agents. 
Jacob George, Shashikant Hegde, KS Rajesh, Arun Kumar conducted a study on the efficacy of an herbal-based toothpaste containing sage in the control of plaque and gingivitis. 
The efficacy of Colgate Herbal over Colgate toothpaste was assessed in this study. At the end of the study, there were statistically significant reductions in the gingival index and the plaque index scores within the test group. It was concluded that the herbal-based toothpaste which contains calcium carbonate, chamomile, sage, myrrh eucalyptus, and sodium monoflurophosphate was as effective as the conventionally formulated dentifrice in the control of plaque and gingivitis. 
Action on gingival inflammation
Pistorius et al.,  conducted a study on efficacy of subgingival irrigation using herbal extracts containing Salvia officinalis on gingival inflammation. A total of 89 patients were included in the study and data were collected at baseline and after 4, 8, and 12 weeks included gingival index (GI), sulcus bleeding index (SBI), plaque index (PI), and probing depth (PD). Subgingival irrigation with a herbal-based mouthrinse led to a significant reduction in both SBI and GI. This regimen can, therefore, be recommended as an adjunctive procedure to reduce gingival inflammation. 
Action on halitosis
Halitosis, or bad breath, most often starts in the mouth. Poor oral hygiene allows food particles to collect on the surface of the tongue, between the teeth or along the gingival (gum) tissue that surrounds the teeth. Naturally occurring bacteria in your mouth then break down those food particles, releasing chemicals that have a strong odor. 
For its bactericidal properties, Salvia officinalis is adequate to kill bacteria that cause halitosis. Mouthwashes of Salvia officinalis is prepared by making an infusion of a spoonful of dried plant per cup of water. ,
| Conclusion|| |
Salvia officinalis has aromatic, carminative, spasmolytic, antiseptic, astringent, antihidrotic actions. The thujone in the volatile oil has an antiseptic and antibiotic action and, when taken as a mouthwash, Salvia deals effectively with throat infections, dental abscesses, infected gums, and mouth ulcers. The phenolic acids in Salvia are particularly potent against S. aureus. Salvia also has an astringent action due to its relatively high tannin content. All these prove the importance of Salvia officinalis in medical as well as dental treatment.
