One must automatically assume that so-called “alternative” remedies are worthless (and maybe even dangerous in some instances) for the simple reason that they are marketed as “alternative” because there is no such thing as “alternative medicine.”
There is also medicine whose safety and efficacy are still being investigated. Because it’s unethical to sell experimental treatments, people who are participating in legitimate clinical trials get the treatments for free, and some are even paid for their time and trouble, and get their associated expenses reimbursed. (Are there any so-called “alternative” practitioners who operate that way?)
And then there are numerous substances, devices, and methods that have already been tested and found to be ineffective but are marketed as “alternative” remedies — unless or until the FDA removes them from the market due to safety concerns.
Before the Dietary Supplement and Health Education Act of 1994, so-called “alternative” remedies were called snake-oil, quackery and health fraud, and those who peddled such nostrums were called charlatans, quacks, and even criminals.
Yet, so-called “alternative” remedies are still just as worthless, and potentially dangerous, as snake-oil was before the DSHEA — it just has a new, “politically correct,” and far more marketable, name.
