The system of marma as chikitsa/ or therapy is related to kalarippayattu , a martial art form from the southern state of Kerala, India. This theory resides under siddha vaidhyam, great works of knowledge which are passed down through select families. The systems of Siddha and
Ayurveda are very much similar. In both systems, the basis of treatment is the three element theory or (three humours). The three humours are Vata (air), Pitta (bile) and Kapha (phlegm). These works are attributed to the sage Agastya.
