#Tulsi

Across Thai gardens and temple courtyards, the distinctive aroma of holy basil—known locally as kaphrao (กะเพรา)—is a familiar and beloved presence. For centuries, Ocimum tenuiflorum, or tulsi as it is called in much of South Asia, has served as far more than a culinary herb or ornamental plant. Revered throughout Thai and Asian traditions for both its healing powers and spiritual significance, holy basil is emerging as a botanical protagonist in the intersection between ancient remedies and modern science. Recent research is now unpacking the many claims surrounding this plant, exploring whether its time-honored reputation as a “Queen of Herbs” holds up in the laboratory as well as in the lore of Thai families.
