Liver is the main seat of metabolism. It is one of the most important organs in the body. According to Ayurveda, it is seat of all metabolism i.e. seat of "Pitta" or Fire energy of the body. Almost everything is processed in the liver, the food, vitamins, enzymes, hormones, neurotransmitters, drugs, alcohol, bacteria, viruses, proteins, carbohydrates and fats are all metabolized by liver. This is not enough but all the preservatives, synthetic flavors, chemicals, food additives, coloring agents, taste maskers etc. put extra burden on liver. Liver has to work hard to process them.
There are many liver diseases which have come up now a days and are growing rapidly. There are diseases like Hepatitis B, Alcoholic liver disease and drugs overload causing liver cells to give away leading to liver cirrhosis. Liver cirrhosis is shrinking or fibrosis of liver leading to degeneration of liver cells.
