Margaret, Would you happen to have any references to peer-reviewed randomized double blind trials that demonstrate that "B12 1000 mg will get rid of homocystine which attacks the [myelin> sheath and stop pins and needles in the fingers"? I realize that you are personally convinced of this. But what is the medical evidence?
I'd add one authoritative site to the good ones you've already listed, Susie. RxList is based on the same information from the FDA approved package inserts, but offers the information in a particularly accessible way, with additional general information on classes and effects of drugs. See http://www.rxlist.com
Chuckie, you don't have to sell supplements to be taken in by articulate but ultimately fraudulent hucksters. Magnesium is certainly a treatment for constipation. But it is not a validated treatment for either anxiety or insomnia.
Likewise, as another participant in the thread has noted, placebo effect can influence outcomes for mainstream medical therapies as well as for alternative therapies. One of the problems with the alternatives is that their originators rather often resist doing the double-blind controlled trials used in mainstream medicine, which are intended to assess whether the positive outcomes are actually the result of the therapy or of placebo effect.
If it seems that I over-generalize my skepticism of alternative therapies, then I'll just have to say "get over it, people." If an alternative therapy actually works, it won't be "alternative" for long. It will be integrated into the mainstream once it is truly validated and standardized. There are many examples of this principle at work -- not least of which is the increasing use of acupuncture and acupressure in pain control.
It's good to have Dr Stacy's confirmation of Susie Margaret's post on this. If I may add my lesser-qualified opinion based on15 years of reading the medical literature on chronic neurological pain and chronic face pain, I completely concur with both.
I have long been suspicious of "theories" proposed by many proponents of so-called "alternative" therapies and supplements. Too many of these hucksters seem to base their claims solely upon testimonial evidence taken under uncontrolled conditions. They conveniently forget that testimonials can also be an outcome of placebo effect, which operates in as many as a quarter of patients who are told that some preparation "will help you" -- even when it is inert.
You're doing fine, Susie. Keep up the good research in support of the visitors.
