Holy basil (Ocimum tenuiflorum), known in Hindi as tulsi, might be the most revered medicinal herb on the planet. The plant has violet flowers and blossoms. The green stems sometimes have a purple tinge.
Medicinal preparations are made from holy basil's leaves, stems, and seeds of the plant. Holy basil is often used in Thai food. It's much spicier than other types of basil and is sometimes called "hot basil."
