The kidney is considered as the filtering unit of the body which removes the metabolic waste products from the body, if the accumulation of metabolic waste is more in the body then the kidney fails in the proper filtration and become leads to disease conditions. According to Ayurveda this disease is caused by the blockage of minute body channels called srotas. The body channels involved in this case, known as mutravahasrotas, carry urine and are responsible for the flow of liquid into and out of the kidneys. If there are blockages in the incoming srotas the kidneys are denied fluids and shrinkage occur. However, if the outgoing channels are blocked, swelling occurs. There are very effective Ayurvedic herbs, such as punanarva that can clean these channels and reduce swelling and rejuvenate the kidneys. Ayurvedic treatment aims at strengthening the kidneys, restoring its filtration capacity and general functioning of the kidneys.
