This system of marmam is part of Siddha Vaidhyam, attributed to the Tamil sage Agastya and his disciples.

It is practiced in almost all parts of Tamil Nadu and in the Travancore region of Kerala. It is supposedly derived from traditional Siddha medicine.

The Kerala Kalarippayat Association formed in 1958 started claiming kalaripiyattu was an umbrella term for all Indian martial arts and gave "Adi Murai" and its component Marma adi as well as silambam and other Tamil martial arts the title of "southern style" of Kalarippayattu although its techniques origins and application are recognized as distinct from those of Kalarippayattu. "Adi Murai" emphasise empty hand techniques. Southern kalaripayat is practiced in most cities of Tamil Nadu, of erstwhile Travancore areas.
