The Science Behind Boiling Tulsi

Tulsi, or holy basil (Ocimum sanctum), is a powerful herb revered in Ayurveda for its adaptogenic and therapeutic properties. It contains bioactive compounds such as eugenol, flavonoids, and antioxidants. Boiling tulsi in water extracts these beneficial elements into a consumable liquid. Simmering on low heat after an initial boil is the optimal method, allowing for the release of essential oils and water-soluble compounds without excessive evaporation.
