What drugs are classified as complementary and alternative medicine?

None: Drugs are regulated by the fda and require proof of efficacy and safety. Remedies used by naturopaths and similar providers have not been tested for either efficacy or safety and in fact are totally not subject to any federal oversight unless they are found to be dangerous in clinical use.

Generally OTC: This is no formal designation by the fda, but most would consider anything that is over the counter, or herbal or homeopathic to be considered complementary & alternative. These compounds lack multi-centered placebo controlled studies published in peer reviewed journals to prove that they work to 'conventional' doctors. Note: 30% of the time placebos work.

Many: Generally this wouldn't be pharmaceutical drugs, but more like botanical (herbal) and nutritional supplements. Herbs given by an acupuncturist/tcm practitioner, or supplements given by an ayurvedic practitioner. Unlike these others, homeopathic medicines are regulated by the fda but are still classified as alternative. http://www.hpus.com/.

Proven vs unproven: By definition, "alternative" is different than modern western medicine. Generally any drug, herb, treatment, or procedure that stands up to rigorous scientific scrutiny is included in modern medicine. The problem is that many alternative practices, herbs etc do not stand up to scientific scrutiny and cannot be shown to work. They therefore remain "alternative". Be careful and watch your wallet.
