Could well be detox. As for other items, in addition to liver cleanses:
Coffee enemas - help open the bile ducts so bile and toxins can be released properly.
Coconut oil - a wonderful item everyone should take, it helps maintain a good bile flow.
Beetroot juice - is also good for the liver and bile flow.
Turmeric - is a cancer fighter itself, especially for smokers, and it helps regulate bile flow.
Milk thistle - is a must as it helps protect the liver and actually regenerate it
Alpha lipoic acid - another liver supplement that also helps fight cancer
Selenium - a third liver supplement that is good against cancer too.
In the Berkson Clinical Study, three women who were facing liver transplants or chemo with interferon (a horrendous treatment with very low success rates for hepatitis and cirhossis), took milk thistle, alpha lipoic acid and selenium, modified their diets a bit and got some daily exercise and restored their liver functions to normal.
