Last year i was on a court jury for a case which involved a death from cancer. This case lasted for weeks, during which time we heard arguments from doctors, scientists and university professors who represented both sides. Each "scientific person" had his/her scientific opinions for taking one side or the other and each one was persuasive to a certain majority who were prone to lean towards one side or the other. At the end my take on the whole thing was that the bottom line for most (but not all) people including a "scientific person" is personal gain.
What i understand from your post is that you had Acne and tried some of Dr. Hulda Clark 's protocols which in your opinion didn't help you, therefore you come to the conclusion that her studies are flawed.
It's up to you what you want to believe or whether or not you consider a certain approach flawed, but for me Liver Flushes and cleanses have been the most effective way of gaining my health back. Last year this time, i was bloated all the time, had diarrhea every 2 days, my eyesight was a lot worse than now, it was difficult for me to walk for 30 minutes and couldn't help myself from eating all the time. But thanks to curezone community i feel a lot better now. I worked 20 years for dentists and i don't trust most dentists or most medical doctors for that matter. They have all been trained in the same institutions and follow the same procedures which are mostly provided by big pharma.
