Essential Oil Components (α-Pinene, β-Pinene, 1,8-Cineole (Eucalyptol), Camphor): These volatile compounds are responsible for the plant's aroma and key actions. They are Antiseptic, Expectorant, and Anti-inflammatory. 1,8-Cineole is notably active in respiratory pathways.

Diterpenoids and Triterpenoids (Ursolic Acid, Oleanolic Acid): These compounds exhibit strong Anti-inflammatory, Antioxidant, and potential Anticancer activities. Ursolic acid is also known for its wound-healing properties.

Flavonoids (Luteolin, Apigenin derivatives): Provide potent Antioxidant support and contribute to the anti-inflammatory and nervine-relaxant effects.

Tannins: Impart the Astringent quality, useful for toning tissues and treating mild diarrhea.

5. Traditional and Ethnobotanical uses covering the Medicinal uses.

Respiratory Discomfort & Jwara (Fever)

Formulation: Leaf tea or steam inhalation.

Preparation & Use: In its native Mexican ethnobotany, a tea made from the leaves is drunk to relieve coughs and chest congestion. As a diaphoretic, it is used to induce sweating and break fevers.

Reasoning: The essential oils, particularly 1,8-cineole, help loosen mucus and clear respiratory passages. The diaphoretic action helps regulate body temperature during fever.

Atisara (Diarrhea) & Grahani (Digestive Disorders)

Formulation: Leaf infusion.

Preparation & Use: A mild infusion of the leaves is used to treat diarrhea and calm digestive spasms due to its astringent and carminative properties.

Reasoning: The tannins help reduce intestinal inflammation and secretion, while the essential oils can relieve gas and cramping.

Vrana (Wounds) & Skin Irritations

Formulation: Leaf poultice or strong infusion as a wash.

Preparation & Use: Crushed fresh leaves are applied as a poultice, or a cooled infusion is used as a wash for minor wounds, insect bites, and skin inflammations.

Reasoning: The combined antiseptic (essential oils), anti-inflammatory (triterpenoids), and astringent (tannins) actions help cleanse, protect, and promote healing in minor skin trauma.

Chittodvega (Anxiety) & Nidranasha (Insomnia)

Formulation: Aromatic tea.

Preparation & Use: A light tea made from the leaves and flowers is used as a gentle nervine to alleviate anxiety and promote restful sleep.

Reasoning: The aroma and flavonoid content have a mild calming effect on the nervous system, similar to many other aromatic Lamiaceae herbs.

7. Disclaimer:

Salvia leucantha is generally considered safe when used in moderation as a tea or topical wash. However, due to the presence of thujone-like compounds (in much lower concentrations than in Salvia officinalis), excessive or prolonged internal use should be avoided. It is not recommended for pregnant or breastfeeding women. The essential oil is not commonly used and should be avoided without expert guidance. Always consult with a healthcare provider before using any herb for therapeutic purposes, especially if you have existing health conditions or are on medication.
