The main job of the kidneys is to separate waste products. They absorb what is required and take away the waste in weewee. the foremost important waste products ar excess Na and water. each kidney contains a couple of million filtering units referred to as nephrons. They eliminate wastes from the body, regulate the degree and pressure of blood, and control levels of electrolytes and blood acidity.
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 mutravaha srotas, 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 occurs. 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. This line of treatment can eliminate the need for reliance upon dialysis.
