Ayurveda Therapy :- SWEDANA OR STEAM THERAPY

SWEDANA OR STEAM THERAPY IN AYURVEDA

It is like Snehana is an independent upakarma,as a purvakarma(post operative) measures generally done after Pachana and snehana, before administration of sodhana treatment,pradhanakarma(main procedures) like Vamana, Virechana,etc.

Swedana is a process to induce sweating artificially in a patient who had already undergone Snehana,etc.The heat is generated directly (saagni) or indirectly (niragni).Swedana liquifies the doshas,clears the obstruction of channels of circulation and directs the doshas to selective places from where they can be expelled easily.

A dry or wet method of sweating is called swedana.It may be full body steam therapy.Special herb decided on the basis of nature and intensity of doshas are fused into the steam and together the heat and herbs dilate the channels allowing the stored ama (toxins) to move back into the digestive system.in swedana the body is made to perspire to loosen and excrete the toxins.by this method as next is to remove toxins from the body through panchakarma(sodhana therapy).

Mechanism of sweating and Swedana karma:

Perspiration or sweat is the substance produced by the sudoriferous glands, sudation therapy activates these glands to produce more sweating so as to flush out the bodily wastes or toxins from the body through the secretory portion of eccrine gland, which are located in the subcutaneous layer and the excretory duct project upwards through the dermis and epidermis to terminate at a pore at the surface of the epidermis.Eccrine sweat glands function through out life and produce a secretion that is more watery than that of apocrine sweat glands.which produce a more viscous secretion in the skin of axilla, pubic region and pigmented areas of the breast,as their distribution is limited to these areas only.

Ayurveda duly recognizing the function of sweat gland like eliminating toxins has successfully adopted and designed as the Swedana chikitsa.

There is a little amount of risk in causing over sweating(continuously) as the vital factors like water,salt,sugar,lactic acid,etc are likely to be eliminated from the body with sweat, hence attending physician should be ready with remedial measures .Even though as safety measured declared persons who are likely to sweat out these vital factors as Ayogya for swedana.

From the panchakarma point of view swedana karma is administered to cause vilayana (liquification) of the aggravated dosha which are already transformed into Snigdha avastha by the pachana and snehana already undertaken in the individual.The vilayana of ama dosha is essential for elimination that can be achieved through vamana,virechana etc.Generally in all pathological conditions the doshas which are in sama condition sticks on various srotamsis creating avarodha or blocking of minute channels.these are being stimulated to move out through pachana ,snehana, and swedana as poorva karma.
