How to treat jaundice without medicines??

You treat the cause of jaundice not the jaundice itself. Give examples: if jaundice is due to cholelithiasis related biliary obstruction, stone should be removed or if jaundice due to liver disease then the disease should be treated accordingly. At times, jaundice can resolve without treatment such as jaundice during an episode of alcoholic hepatitis or acute hemolysis. Take care.

You may want to be evaluated to know the cause of the jaundice, if you do not already know, so that it could be appropriated managed before things get worse. The liver is a single organ that is very important to the body and most diseases are best managed early rather than later. If it is nothing serious the jaundice would fade by itself.
