Excess consumption of hydrogenated fats, overcooked meats, refined starch (especially white flour), refined sugars, excess use of alcohol and drugs, including nicotine leads to hardening, congestion and impairment of the liver. Raw tomatoes are known to be very effective in reducing inflammation of the liver due to hepatitis and cirrhosis. A diet of tomatoes taken for 1-3 days exclusive of other food, either bulk or raw juice; may be mixed with carrot juice for flavor and extra therapeutic benefit is said to be an excellent remedy.
