It is one of the eight specialized branches of Ayurveda and the most important among them. It deals with matters relating to general Medicine. It deals with causes, condition, symptoms, progress of the disease, cure of ailments affecting the body and it also deals with diagnosis and prognosis as well as the therapeutics and dietetics. 'Kaya' means 'whole body', so literally it means diseases affecting the body in general, but technically it represents 'Agni' or the pitta that carries out the changes including metabolic ones in our body. The derangement of this tenet 'Agni' is the root cause of disease. So treatment in general means correction of Agni, and so Kayachikitsa is nothing but the correction of Agni or keeping the function of Agni in optimum. The school of Kayachikitsa or School of Medicine led by Punarvasu Atreya is known as Atreya Sampradaya. Charaka states with emphasis that success in treatment depends not only on the efforts of the physician, but on the optimum qualities of the Physician, Drug, Nursing Care and Patient. These are the quadruple (four-fold) aspects of chikitsa - "Bhisak Dravyanyupasthata Rogi Pada Catustayam".
The cells in every living being undergo modification during growth. The rate of this degeneration increases in old age. Rasayana Chikitsa, also known as rejuvenation therapy, reduces the rate of degradation and thereby rejuvenates the body.
As a person gets older, the cells in his body degenerate more rapidly, resulting in several disorders and ageing difficulties. Ayurveda has an effective remedy for this problem in the form of Rasayana Chikitsa. The body is massaged with medicated herbal oil or herbal cream. Sirodhara and medicated steam baths are also done along with intake of rejuvenated Ayurvedic medicines. This lasts for 90 minutes to 2 hours a day for 7 to 14 days.
