proof

think alternative therapies lack scientific research?
read this:
"The Office of Technology Assessment, a branch of the United States Congress, with the help of an advisory board of eminent university faculty, has published a report with the conclusion that, " only 10 to 20 percent of all procedures currently used in medical practice have been shown to be efficacious by controlled trial."
Therefore, 80% to 90% of medical procedures routinely performed are unproven.
That report further points out that the research which purports to prove effectiveness of the remaining 10% to 20% of medical procedures is largely flawed, and " . . many of the other procedures may not be efficacious."
