Never heard of it before, I guess it's a basil....Now I know how Tulsi Gabbard got her name, since she's part Indian...

"Tulsi, Ocimun sanctum, is named after the Hindu goddess who chose to be reincarnated as a sacramental herb to express devotion to the god, Vishnu. Everything associated with the Tulsi plant is considered sacred, the soil, air and the water nourishing her. Traveling in India, or visiting people “in the know here in the U.S.”, you will find Sacred Basil plants outside of people’s homes. Tulsi gives the protection of the divine from birth to death and opens the heart and mind. Mala beads are made from Tulsi stalks. All these gifts in exchange for caring for this beautiful aromatic plant."
