Ayurveda is an ancient system of holistic medicine originating in India 5000 years ago. In Ayurveda, three fundamental forces of energy [or Doshas] govern all living processes.
 
There are,
Vata: the principle of air and movement.
Pita : the principle of fire and transformation.
Kapha: the priniciple of water for cohesion and support.
 
In Ayurveda medicine, it is thought that good halth depends on a harmonious relationship between the three Doshas which govern all living processes.
 
All these teas are based on the principles of Ayurveda.
