I've heard from friends that the herb Milk Thistle helps repairs the liver and promotes the regeneration of new healthy cells. Not sure how well it works. I guess it wouldn't hurt to try it. 21 days and counting till liver damage!
Milk thistle is good for people who already have liver problems. It wont hurt to take it but taking a few days off from drinking after your trip will allow your liver to recover. The good news is that it is very inexpensive. Any local nutrition store should carry it.
Yeah, it is, but it's not a miracle worker. It is commonly used by people who are doing a lot of prescriptions for an extended period of time. It doesn't necessarily 'fix' but it can aide in supporting it. Here is a short layman's term article about it. Milk Thistle | Milk Thistle Benefits | Milk Thistle Uses
