A common traditional use of sage is for smudging, a process where a plant, often sage, is burned to purify the “mind, body, heart and spirit” of those who enter a space. [3] Other medicinal uses for sage are as an antifungal, digestive aid and to help with symptoms of arthritis. [11, 20] Generally, it is applied topically to fungal infections or to help with pain from arthritis or sprains. [11] Small quantities of tea made from sage could be consumed to help with congestion, colds, coughs and fevers. [8] The bark was also used for weaving. [20]

Although the diversity of species in the Artemisia genus and the large volume of literature surrounding sage with regards to essential oil and other therapeutic uses makes it difficult to find research specific to the species and the bioactive components it contains, the leaves of the sage plant have been shown to contain lactones, flavonoids and to exhibit antioxidant activity. [2] It is also likely to contain other bioactive constituents including other phenolic compounds. [1, 4] Fig 11.4 shows compounds present in different Artemisia species. [1, 4]

Conservation Note: White sage is currently threatened by over-harvesting and commercial poaching, causing concern among Indigenous communities about cultural appropriation and ecological sustainability. [7]
Traditional Indigenous Uses
Sage had always been used to purify both the body and the spirit, its smoke carrying prayers and cleansing away heaviness or sorrow. [8, 1, 3] In ceremonies, it was burned in smudges or placed in sweat baths, the rising smoke a blessing for all who gathered. [8] Beyond its spiritual strength, sage was deeply valued as medicine. The people brewed its leaves into tea to ease coughs, sore throats, and chest congestion, and to bring comfort to those suffering from colds, bronchitis, or asthma. [5, 6, 8] The same tea calmed troubled stomachs, relieving cramps, indigestion, and diarrhea. [11]
Sage was used by women to bring balance to their bodies, soothing cramps, regulating menstruation, and aiding recovery after childbirth. [22] A wash made from its leaves healed cuts, bruises, and burns, while poultices drew out infection from the skin. [11] Some used a single sage seed to clear dust or irritants from the eyes, and its strong tea reduced fever and sweating during illness. [5] The people also chewed sage leaves for toothaches or used the tea as a mouthwash to keep gums healthy. [11] Its seeds could be ground into food, and its leaves were sometimes used to flavor meals. [1, 3]
Structure-Activity Relationships
- Bicyclic Monoterpene Structure: Enables membrane penetration, volatility for inhalation delivery, receptor binding for neurological effects [1, 2]
- Catechol Groups (Carnosic Acid, Rosmarinic Acid): Powerful electron donors for antioxidant activity, metal chelation capability [9, 17]
- Multiple Phenolic Hydroxyl Groups: Free radical scavenging, enzyme inhibition, antimicrobial protein precipitation [17, 18]
- Lipophilic Diterpene Backbone: Cell membrane permeability, accumulation in lipid-rich tissues (brain, cell membranes) [19]
- Carboxylic Acid Groups: Water solubility, ion channel modulation, enzyme active site interactions [10]
- Volatile Nature of Monoterpenes: Enables respiratory delivery through smoke or steam, rapid absorption through mucous membranes [21, 2, 3]

Preparation and Safety Considerations
Traditional Tea Preparation [1, 6]
- Use 1-2 teaspoons dried sage leaves per cup
- Steep in hot water (80-90°C) for 5-10 minutes
- Strain and drink 1-3 times daily
- Fresh leaves can also be used (slightly stronger)
Safety Notes
- Thujone Content: High doses or prolonged use can be neurotoxic due to thujone; traditional preparations in moderation are safe [4]
- Pregnancy: Traditionally used for menstrual regulation; may stimulate uterine contractions – avoid during pregnancy except under guidance [11]
- Lactation: Can suppress milk production; avoid during breastfeeding unless specifically desired [11]
- Epilepsy: High thujone content may lower seizure threshold; use with caution [4, 10]
- Diabetes: May lower blood sugar; monitor if on medications [10, 18]
