Tulsi (scientific name: Ocimum sanctum) is also called holy basil because of its religious and spiritual significance in the Indian culture. It is a perennial (grows in all seasons) herb native to India and mainly grows in the tropical areas of South East Asia. Tulsi grows as a branched shrub that may reach up to a height of 60 cm. It bears fragrant leaves and furry branched stems that may have tiny white to purple flowers. The plant is regarded as the “queen of herbs” or “mother medicine of nature” in Ayurveda because of its various health benefits. Ayurveda, the traditional form of Indian medicine, regards tulsi as an adaptogen.
