A drug that reverses severe liver damage could be used to treat disease in heavy drinkers who find it impossible to give up alcohol. Scientists developed the drug after discovering a way to prevent the formation of excessive scar tissue caused by cirrhosis, hepatitis and other medical conditions.

To their surprise the drug not only slowed progression of the disease but also reversed damage to the organ.

If this makes it to market, it will be a fantastic break though.

Hopefully this research could be adapted to repair the kidneys and the heart.
