Holy Basil, or Tulsi, is the most sacred and widely grown herb in Indian households, revered in Hindu tradition and central to Ayurveda. Native to the Indian subcontinent, this aromatic perennial herb forms a small bushy plant with fragrant green or purplish leaves and slender spikes of tiny purple-white flowers. Both Rama (green) and Krishna (purple) Tulsi are popular. Beyond its religious importance, Tulsi is prized for its medicinal leaves used in teas, kadha and remedies for cough, cold and immunity. It is easy to grow in pots and is believed to bring health, purity and positive energy to the home.
