Placebos don't cure chronic diseases overnight. Please point out a placebo that cured a disease.
Nor do medicines. You again show in this post you don't understand what a double blind medical trial is and why it's important.
If there is a body of research and knowledge on the matter, on what happens to people with a chronic illnesses when you give them nothing or something non-effective, then you already have that research, and conducing that full study is not actually necessary. There are many studies which refer to previous literature as their control.
In a previous example, phosphorous cured a hopeless case of disease. Did that doctor need to give someone a placebo and sentence them to death before reporting his successful result? No.
Are you having trouble comprehending my question? Let me make this simple..... Choose A, or B. A single letter response would suffice.
Definition of clinical study:
A) A controlled study is mainly needed when you don't know about the disease.
B) A clinical study that includes a comparison (control) group. The comparison group receives a placebo, another treatment, or no treatment at all.
None of that is needed. The doctors know what a hopeless case is, and the doctors know what a chronic disease is.
You are playing difficult because you have no evidence to contradict the links given, and really have no standing argument on the matter.
