Tulsi, also known as holy basil, is one of the most extensively studied herbs in Ayurvedic tradition, available in several varieties including Rama, Krishna, and Vana tulsi, each with slightly different phytochemical profiles. Research suggests that tulsi contains a rich array of bioactive compounds, including eugenol, rosmarinic acid, and ursolic acid, which may contribute to its reported anti-inflammatory, antimicrobial, and adaptogenic properties. Studies indicate that tulsi may support the body's stress response by helping to modulate cortisol levels, and preliminary research has explored its potential role in supporting healthy blood sugar levels, respiratory function, and immune activity. While the traditional use of tulsi spans thousands of years, modern clinical research continues to investigate the full scope and mechanisms of its potential benefits.
