There are actually three varieties of tulsi commonly used in traditional Ayurvedic medicine: Vana, Rama, and Krishna Tulsi.

Vana Tulsi has a lemony flavor. In Ayurvedic medicine, Vana Tulsi is thought to moderate the wind principal, Vata, which governs breath, blood flow, and mental clarity.

Rama Tulsi's flavor has subtle notes of licorice and clove. In Ayurvedic medicine, Rama Tulsi is thought to moderate the earth principle, Kapha, which governs weight, growth, and joint health. 

Krishna Tulsi has purple leaves and a peppery taste. In Ayurvedic medicine, Krishna Tulsi is thought to moderate the fire principle, Pitta, which governs digestion and metabolism.
