Charaka Samhita, Vimanasthana 5.13
Kandara twak moola Mamsavaha Srotasam — The tendons and skin are the roots of the muscle channels. Impairment produces growths (Arvuda), excess muscle tissue (Adhimamsa), and fibrous conditions (Granthi).

Classical documentation

Roots: Kandara (tendons) and Twak (skin — the outer boundary of the muscle layer)

Primary Dosha: Kapha primarily (Mamsa has heavy, solid qualities); Vata for movement of nutrition through muscle channels

Classical conditions: Arvuda (muscle tumours/masses), Adhimamsa (excess muscle growths), Granthi (fibrous cysts), Upakusha (gum conditions — as Mamsa of the oral cavity), muscular stiffness and hypertrophy

How these channels are impaired

Excessive sedentary lifestyle; sleeping immediately after meals (Divasvapna specifically impairs Mamsavaha Srotas through Kapha accumulation in the channels); eating excessive meat; lack of movement

Classical significance

Mamsavaha Srotas corresponds to the musculoskeletal system's soft tissue component — muscle fibres, fascia, tendons, and the dermal layers. The classical documentation of tumour-type conditions (Arvuda) as Mamsavaha Srotas Dushti reflects the modern understanding of sarcoma and other soft tissue neoplasms as conditions of the muscle tissue system.

Primary herbs for this Srotas
Ashwagandha (Balya — muscle nourishing), Bala (primary Mamsa Dhatu builder), Nirgundi (Mamsavaha Srotas clearer in Vata-Kapha conditions)
The four types of Srotas impairment
Charaka Samhita documents four ways any Srotas can be impaired: Atipravritta (excessive flow — too much output); Sanga (obstruction — blockage stopping normal flow); Vimarga Gamana (flow in wrong direction — reflux, bleeding upward, etc.); Siragranthi (knotting/constriction — localised channel narrowing). These four apply to every Srotas — the specific disease produced depends on which channel is impaired and in which of these four ways.
