iZO Liver Detox contains therapeutic levels of the most powerful liver herbs known. Milk Thistle can help the liver because it nutritionally supports its functioning. It can help to increase the flow of fat-emulsifying bile. When the liver is toxic, it dumps toxins into your colon via bile. Then, if your colon is toxic, (which almost everyone's is) these toxins get reabsorbed into the blood stream and much of them are sent back to the liver, and then back to the colon via bile, and then back to the liver, etc. Much research has shown Milk Thistle to be able to protect the liver from the damaging effects of a wide variety of common toxins, including alcohol. Milk Thistle extract is so powerful it has been reported to counteract even overdose of otherwise lethal drugs! Milk Thistle is also a powerfully effective antioxidant, and it can increase glutathione reductase levels (this is a crucial metabolic antioxidant enzyme) in liver cells. Milk Thistle's antioxidant and other properties positively affect other areas of the body as well. It has been shown, among other things, to nutritionally support persons with skin cancer. A root extract blend of Japonica, Dandelion Root, and Kurroa has been added for their healing effect.
