1.) Mercola is on Quackwatch.com and was warned by the FDA to stop spreading misinformation about medications.

2.) So much of what is in this article is blatantly false. Beta blockers are actually one of the few medications that have shown to actually reduce morbidity and mortality. They are essential in the treatment of patients with heart failure.
3.) the article is one mans opinion based on one paper out of the UK. And in that paper they use generalizations like "may have" or "could possibly". This article is the equivalent to the national enquirer. It literally says nothing.
4.) the article is not peer reviewed.
Philly, you like to post links to BS like this frequently but you've yet to post anything substantial. Everything is one quacks opinion. I'm not trying to be ugly but honestly, this is ridiculous.
Beta blockers have been studied 100's of times and continue to be studied. We dont use them based off of some doctors study out of the netherlands. They are used because they continue to show benefit in a large spectrum of patients.
