The body fluids such as blood (rakta) and lymph (rasa) serve to carry wastes (malas) away from the tissues that produce them. The urinary system removes water (kleda), salt and nitrogenous waste. The urinary system also helps to maintain the normal concentration of water electrolytes within the body fluids. It helps to regulate the volume of body fluid and aids in the control of red blood cell production and blood pressure. Thus, urine helps to maintain the balance of the three humours, Vata- Pitta -kapha and water.
Clinical Examination of Urine
In a clean vessel, collect the early morning urine in mid -stream, observe the colour. If the colour is blackish- brown this indicates a Vata disorder, if the colour is dark- yellow a Pitta- disorder, also when there is a constipation all the body has less intake of water, urine will be dark yellow. If the urine is cloudy there is a, Kapha- disorder. A red colour in the urine indicates a blood disorder.
Oil Drop Test-
With a dropper, place One drop of sesame oil in a sample of urine. If the drop spreads immediately, the physical disorder is easy to cure. If the drop sinks to the middle of the urine sample this indicates, illness is difficult to cure. If the drop sinks to the bottom illness may be very difficult to cure.
If drop spreads on the surface in Wave- like movements, this indicates Vata disorder. If drop spreads on the surface with multiple colours visible like a rainbow, this indicates Pitta disorder. If drop breaks up into pearl like droplets on the surface of urine, this indicates kapha disorder.
Normal urine has a typical uremic smell however, if the urine has a foul odor, this indicates that there are toxins in the system. An acidic smell which creates a burning sensation indicates, excess Pitta. Sweet smell of urine indicates a possible diabetic condition. In this condition, the individual experiences goose bumps on the skin while passing urine. Gravel in the urine indicates the the likelihood of stones in the urinary tract.
Relationship between skin and kidneys
There is a special relationship between the skin and the kidneys since the excretion of the watery waste is primarily the function of these two organs. Thus, perspiration is indirectly related to the formation of urine. Like urine, perspiration is related to Pitta. In summer, people perspire profusely, but their urination is reduced because waste products are eliminated through perspiration. In winter many people perspire less and urinate more.
Excessive urination may cause too little perspiration prodution production and excessive perspiring may result in a scanty volume of urine. Thus, it is necessary that the production of perspiration and urine be in balance. Diabetes, Psoriasis, dermatitis and Ascites are example of diseases resulting from an imbalance of perspiration and urine in the body.
Excessive perspiration reduces body temperature and creates dehydration. In the same way too much urination also creates dehydration, and also will cause coldness of the hands and feet.
