Milk thistle not effective in.......
Milk thistle not proven effective in lowering mortality in alcoholic or hepatitis B or C liver disease

Milk thistle, a widely used alternative medicine, is not proven effective in lowering mortality in alcoholic or hepatitis B or C liver disease, according to a systematic review of current evidence.
While some studies found that liver-related mortality may be significantly reduced in patients treated with milk thistle, these findings were not duplicated in the higher quality clinical trials.
However, milk thistle was found safe to us with no serious side effects and with participants perceiving improvement in symptoms ? although no more than with placebo.
Dr. Andrea Rambaldi, visiting researcher at the of the Centre for Clinical Intervention Research at Copenhagen University Hospital, led a team that reviewed 13 randomized clinical trials involving 915 patients who were treated with milk thistle or its extracts.
Participants had acute or chronic alcoholic liver cirrhosis, liver fibrosis, hepatitis and/or steatosis, and viral-induced liver disease (hepatitis B and/or hepatitis C). Patients with rarer specific forms of liver disease were excluded.
All the trials compared the efficacy of milk thistle or any milk thistle constituent versus placebo or no intervention in patients with liver disease. "There is no evidence supporting or refuting milk thistle for alcoholic and/or hepatitis B or C virus liver diseases," the authors found.
The review appears in the most recent issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.
According to the Centers for Disease Control and Prevention, 170 million people worldwide are infected with hepatitis C, and 2 billion are infected with hepatitis B.
While a vaccine exists to prevent hepatitis B, there is no vaccine for hepatitis C.
Although the virus can be cleared in a handful of patients, many strains are resistant to treatment. Drug therapies that focus on long-term suppression of the virus are expensive, and many patients develop a resistance. The current gold standard treatment, which combines injections of interferon and ribavirin, has serious side effects and is hard for patients to tolerate.
With lack of effective treatment for liver disease, researchers have been looking for alternative therapies that curb symptoms with minimum adverse effects on patients.
Milk thistle and its extracts have been used since the time of ancient Greece for medicinal purposes, are currently widely used in Europe for liver disease, and are readily available in the United States at alternative medicine outlets and outdoor markets.
G. Thomas Strickland, M.D., Ph.D., professor at the University of Maryland School of Medicine, has been studying the role of silymarin, an extract of milk thistle, in preventing complications of chronic hepatitis virus infection. Strickland says that the exact mechanism of action of silymarin is unclear.
A problem with current trials, according to Dr. Strickland, is that the dose of silymarin administered, typically 140 mg three times daily, is too low. "I would certainly double it," he says, "especially since at the current dose we're not seeing any improvement in acute viral or chronic hepatitis, and we've shown that silymarin is totally safe."
" The problem is, there is no cure for viral hepatitis except bed rest and diet, and treatments like silymarin are worth pursuing," Strickland says, calling for more research funding.
" We should consider doing randomized clinical trials with higher doses of silymarin," Dr. Rambaldi concurs.
According to the National Center for Complementary and Alternative Medicine , a part of the National Institutes of Health, studies in laboratory animals suggest that silymarin may benefit the liver by promoting the growth of certain types of liver cells, demonstrating a protective effect, fighting oxidation (a chemical process that damages cells) and inhibiting inflammation.
In their review, Dr. Rambaldi and colleagues conclude, "Milk thistle could potentially affect alcoholic and/or hepatitis B or C virus liver diseases. Therefore, large-scale randomized clinical trials on milk thistle for alcoholic and/or hepatitis B or C liver diseases versus placebo may be needed."

i use both liv-52 and milk thistle and hope for the best but you cant argue with this you see in high quality studies it didnt show any good effect but like they said maybe if we use higher doses.

i think liv 52 and tylers liver detox are probably better than milk thistle

Guys, be careful to actually read what the study says. First off, it says that milk thistle didn't prolong the lives of those with the studied diseases not that milk thistle was ineffective. Second, even the researcher said that the dose used in the study was too low and should be higher when studied. They were only taking 420mg per day. I routinely taken over 1000mg. So take this for what it is.

Where can you get liv-52?
05-15-2005, 01:20 PM #7
do a google search for liv 52 and you will find plenty of supp stores in usa who sell it.
The interesting thing about the survey is that they give it to people who already have liver disease. hopefully none of us fall into that category. I was lead to believe Milk Thistle helps protect the liver from becoming diseased seems to me thay were trying to slam the barn door after the horse had bolted!!

Im taking 9 caps. of milk thistle a day,im not sure about efects on my liver but i think its better than nothing.

hepatitis due to virus B or C is different from toxic hepatitis.

It's a good thing we aren't using it because we're alchoholics...because maybe it won't work for them...but it certainly works to protect your liver from potential damage from Anabolic Steroids :

Hepatoprotective effects of silymarin in androgenic-anabolic steroid-induced liver damage
[Article in Serbian]
Radovanovic D, Jovanovic D, Mihailovic D, Rankovic G, Stojiljkovic N, Dimitrov V.
INTRODUCTION: The use and abuse of anabolic-androgenic steroids (AAS) commonly induces liver damage. MATERIAL AND METHODS: The study included 40 male Wistar rats, divided into 4 groups of 10 rats each. Animals in the first experimental group (M), were subjected to progressive systematic forced swimming test, 5 days a week, during 8 weeks. Animals in this group were treated with AAS methandienone, 2 mg/kg BW/day, per os, before swimming, 5 d/w for 8 weeks. After swimming, animals were given three times more food than the laboratory animals of the same age and kind. Animals in the second group (M+S), were subjected to progressive forced swimming test, 5 d/w 8 weeks. Animals in this group were treated with methandienone equally as the experimental group M and received the same amount of food. Apart from that, they received silymarin 20 mg/kg BW/day. Animals in the third group (K), represented the control group, which was neither subjected to swimming test, nor treated with methandienone or silymarin. Animals in this group received the same amount of food as animals in groups M and M+S. Animals in the fourth group (C), also represented a control. This group was not exercised nor treated, and animals received a standard amount of food for laboratory animals of this kind and age. Quantitative analysis of obtained hemataxylin-eosin, periodic acid shift and enzymohistochemical preparations was processed using Digital Image Analysis System: Microimage 3.0. RESULTS: It was established that processes in the nuclei of animals in groups M and K were significantly more intensive (p<0.001) in relation to groups M+S and C. The investigation of glycogen showed significantly higher density in the cells of groups M and M+S in comparison to groups K and C. Also, there was a significant difference between groups M+S and M. Density of enzyme activity of glutamate dehydrogenase in hepatocytes of animals in the group M+S was significantly higher in relation to the remaining three groups. A statistically significant difference was not found in enzyme activity of succinate dehydrogenase and lactate dehydrogenase. DISCUSSION: In cell nuclei of animals in the experimental group M, in the absence of silymarin effect, methandienone causes damages which induce regenerative processes and in this way increase high intensity activity. Silymarin significantly increases the glycogen density in hepatocytes. Increased activities of GDH are attributed to cell vitality. CONCLUSION: The present results show hepatoprotective effects of silymarin in androgenic-anabolic steroid induced liver damage.
