Swedana

The second major aspect of the preparatory procedures of PurvaKarma is called swedana, the theraputic application of heat to the body. Though swedana literally means "sweat", the main purpose of swedana is not to poduce sweat, but to dilate the body's shrotas or channels so that oleation's objective - removing anna from the dhatus - can be easily achieved. Sweat results naturally when the channels widen. In addition, the application of heat also counteracts the coldness of both vata and kapha, reduces the body's stiffnes and heaviness, and counters the slow, heavy and sticky attributes of ama. As the influence of agni bhuta increases, it begins to soften or melt ama's density. Ama gets liquified and shrinks in volume, making it easier to be carried from the tissues. The heating action of swedana also mobilizes the doshas, which are responsible for transporting these toxic waste materials from the deep tissues to the gastrointestinal tract. • TYPES OF SWEDANA NADI SWEDA (Penetrating Heat), Nadi, which means "tube", uses steam from an herbal water decoction. Nowadays, this method is facilitated by the use of a pressure cooker and a nylon reinforced plastic hose which eases the steam's application to the body's surface. Nadi is a more penetrating type of wet heat than bashpa, because the steam actively drives the heat and oil deep into the tissues through the pores of the skin. Although this type of steam treatment is given to the whole body, it focuses on the thick and complex structures of the joints to improve their mobility. Nadi swedana usually lasts for five to seven minutes. Outside the panchkarma process, it can be used with snehana for reducing pain, muscle pain, muscle spasm and rigidity in localized areas. This treatment can be very helpful in the palliative management of backache, inflammation of the spine, hip and knee, and for generalized muscle pain. BASHPA SWEDA (Steam Heat), the second type of agni swedana, generally folows immediately after nadi swedana is administered. Bashpa literally means "steam" and unlike the more directed form of heat used in nadi swedana, bashpa applies steam evenly to the entire body. Bashpa sweda uses a sweat box, in which the patient either sits or lies down on his back. Every part of the body is exposed to the heat except the head, as it cannot tolerate high range of temperatures. In fact, a technician continuously places cool compresses on the forehead during the treatment to maintain the head's normal temperature. To avoid dehydration, the patient is given a glass of water before administering bashpa sweda. These small, one-person steam baths are normally constructed of wood with a thermostat that allows their temperature to be easily controlled. Herbal steam is released into the box according to the needs of the patient. The duration of the treatment is seven to ten minutes, or until sweat begins to bead on the face and forehead. • CONTRA - INDICATIONS : Though Bashpa sweda is an important preparatory procedure, it is not appropriate for people with heart disease or hypertension, since the heat may cause a rise in heart rate and blood pressure. Individuals with blood disorders, such as anaemia or leukaemia, also cannot tolerate the temperatures used to induce a full body sweat during this treatement. Share
