About
Ocimum tenuiflorum, commonly known as tulasi, tulsi, or holy basil, is an aromatic perennial plant in the family Lamiaceae. It is widely cultivated throughout the Southeast Asian tropics. It is native to tropical and subtropical regions of Asia, Australia and the western Pacific. This plant has escaped from cultivation and has naturalized in many tropical regions of the Americas. It is an agricultural and environmental weed.
Tulasi is cultivated for religious and traditional medicine purposes, and also for its essential oil. It is widely used as an herbal tea, commonly used in Ayurveda. It has a place within the Vaishnava tradition of Hinduism, in which devotees perform worship involving the plant or its leaves.
