Tulasi is a fragrant, much branched subshrub of the mint family grown in courtyards and temple gardens across the whole of India, from the plains of the north to the coasts of Kerala and Tamil Nadu, and found wild on waste ground in the warmer states. Two varieties are recognized in practice: the green leaved Rama tulasi and the purple tinged Krishna tulasi, which is regarded as the stronger medicine. Ayurveda treats the leaf as a warming, drying, pungent herb that clears kapha from the chest and head, kindles digestion and protects against infection, fever and the ill effects of poor air and water. Its place in daily worship reflects how completely it has been woven into Indian domestic medicine.
