Ocimum sanctum (holy basil), called Tulsi in India , is ubiquitous in Hindu tradition. Perhaps its role as a healing herb was instrumental in its "sacred" implication. Tulsi have antibacterial, anti fungal, antiviral & de-toxicant properties, its regular use prevents heart attacks. The leaves in the form of a paste are used in parasitical diseases of the skin and also applied to the finger and toenails during fever when the limbs are cold. The drinking of Tulsi-leaf tea keeps one free from cough and colds and other ailments associated with 'Kapha' dosha in the body.
This tea is an instant pick-me-up (energy drink) also.
