Tulsi, revered as the “Queen of Herbs” in Indian tradition, holds a unique position at the intersection of Ayurvedic medicine, spiritual practice, and daily household use. Bhavaprakasha describes Tulsi as Kapha-Vata shamaka with tikshna (sharp) and deepana (digestive fire kindling) properties. Three primary varieties are recognised in classical texts: Krishna Tulsi (dark/purple), Rama Tulsi (light green), and Vana Tulsi (wild forest variety).

Botanical Description
Ocimum tenuiflorum is an aromatic, erect, much-branched sub-shrub growing 30–60 cm tall. The plant is pubescent with simple, opposite, elliptic leaves that are aromatic when crushed. Flowers are purplish in elongated racemes. The entire plant is fragrant due to essential oil glands on the leaves and stems.

Native to the Indian subcontinent, it is now cultivated worldwide in tropical and subtropical regions.
