The urinary tract se is made up of the kidneys, ureters, bladder and urethra. Water is filtered in kidneys and that which is unabsorbed, comes out as liquid waste to be eliminated in the form of urine. Excessive consumption of salt results in water retention and weakens activity of kidneys. Their improper function leads to disorders in lumbar spine, knees and joints. Three main substances are eliminated from the body: the urine, the stool and the sweat. The Ayurvedic medicine pays a lot of attention to a healthy and regular excretion, because many of psychosomatic disorders start in too impure large intestine. The final stage of the digestive process takes place here, where the pranic energy from the daily diet is assimilated in the body. Good peristalsis and regular excretion leads to healthy function of the large intestine. Constipation creates toxic substances that support or cause negative thinking and irritated behaviour. Regular purification and proper functioning of the large intestine and kidneys is of paramount importance for good bodily health, mental balance and optimistic feeling of life.
