The term Chikitsa means treatment or therapy.  . It is important to note that the status of health and etio-pathogenesis of disease depends upon status of Agni (digestion and metabolism). (Cha.Chi.15/4) Therefore, the treatment is based upon correcting the digestion and metabolism.
Literally, the term Kaya comprehends entire process of metabolism, rather than either anabolism as denoted by Deha or catabolism denoted by Sharira. Therefore, the word “Kaya-chikitsa” indicates medical management of diseases caused by impaired “Agni”. The medical practice of Kayachikitsa is based upon an intimate understanding of nutrition and the factors responsible for digestion, absorption and metabolism. Chikitsa Sthana is the most important section focusing on objectives of Ayurveda for preservation of health and treatment of diseased.(Cha.Su.30/25)
