The presence of camphor and camphene in this essential oil gives it an antifungal property. This oil is capable of inhibiting fungal infections, both internally and externally, and gives relief from fungal infections like dysentery, skin diseases, Athlete’s Foot or dermatitis. This property is one of the causes behind its use in skincare products.
The components in sage essential oil which give protection against fungal infections also provide protection against microbial infections too. Therefore, you can protect small wounds or cuts from developing irritating or potentially dangerous infections, as confirmed by a report published in the African Journal of Biotechnology.
This oil is equally useful at countering bacterial infections since it kills bacteria and inhibits their growth in the body. This property can also be used to heal ailments like bacterial infections in the ears, nose, throat, eyes, genitals, urethra, colon, intestines as well as on the skin and in wounds.
This is perhaps the most valuable aspect of the sage essential oil and the reason behind its extensive use in anti-aging and skin treatment products. According to a study published in the Journal of Traditional and Complementary Medicine, sage gets it potent antioxidant power from rosmarinic acid and carnosic acid. Antioxidants, as the name suggests, act against oxidants or free radicals in the body, which are the main causes of aging. These antioxidants slow down aging and prevent symptoms like wrinkles, sagging skin, and muscles, reduction in vision and hearing capabilities, malfunctioning of the brain, memory loss, degeneration of tissues, macular degeneration, and nervous disorders.
Since it has antimicrobial, antibacterial, and antifungal properties, it serves as an antiseptic for wounds, surgical incisions, post natal injuries, ulcers, and sores.
It reduces inflammation on the skin, inflammation due to fever, and prevents the entry of poisonous material into the bloodstream. It also reduces the effects of excessive intoxicants and narcotics, ingestion of excessive salty or spicy food, the influence of very hot winds, etc. A study in Pharmaceutical Biology  journal suggests that it helps cure inflammation in the stomach, intestines, and excretory tracts too.
This property of sage essential oil is useful in treating all problems that arise from spasms, including pain in the stomach, chest, and intestines, as well as coughs, convulsions, and cramps.
Cholagogue & Choleretic
According to the International Journal of Biology, sage promotes the discharge of bile. Sage essential oil helps in digestion, soothing the stomach, and improving the functionality of the whole digestive system against inflammation caused by excessive acids. It also neutralizes acids in the stomach and the bloodstream, thereby providing relief from acidity and acidosis, which in turn protects us from peptic ulcers due to acidity, as well as from boils, eruptions, and skin diseases that occur when acid levels rise in the blood.
This is yet another property which has given sage essential oil a strong place in the world of cosmetics as a key ingredient of anti-mark and anti-spot cream. Sage oil helps to eliminate scars, post-natal abdominal stretch marks, and blemishes caused due to boils, pox, and sores. It also helps in quick healing of wounds and incisions.
It acts as a digestive medicine in case of indigestion by facilitating the decomposition of food. It does so by promoting the secretion of bile and gastric juices and by inhibiting microbial growth in the digestive system, which interferes with the digestive process.
The antibacterial, antifungal, antimicrobial, and antiseptic properties of essential oil of sage make it an effective disinfectant, as it gives sound protection from both internal and external infections.
This essential oil regularizes menstrual cycles and helps relieve obstructed menses. It activates certain hormones, such as estrogen, which helps to bring about clear menstruation and gives relief from problems like a headache, nausea, weakness, fatigue, depression, mood swings, and other associated symptoms of periods.
If all the properties of this essential oil are to be described with a single term, ‘stimulant’ would be the appropriate one. Most of the properties it displays are different expressions of this property. It stimulates the brain, nervous system, liver, spleen, and the circulatory and excretory systems, thereby activating and optimizing them.
