Ocimum tenuiflorum. Holy Tulsi basil, also known as sacred basil, is a highly revered herb in Ayurvedic medicine, renowned for its medicinal and spiritual significance. This aromatic plant features green or purple leaves with a slightly peppery and clove-like flavor. Known for its adaptogenic properties, Holy Tulsi is used to reduce stress, boost immunity, and promote overall well-being, making it a valuable addition to any herb garden. Holy basil grows much like traditional basil varieties but does not bush as much.
