First:There is no such thing as "alternative" medicine. Something either works, in which case it is medicine, or it doesn't, in which case it is quackery.Second:Many agents seem to work because of the placebo effect (if you don't know what this is, look it up). "They" conduct extensive double blind clinical studies to separate the quakery from the medicine, and to eliminate the placebo effect. This is expensive and time consuming, but results in products that provide real cures. The average life-expectancy in this country has increased by over 30 years in the past century. People no longer die of smallpox, cholera, TB, typhoid fever, etc. becasue "they" cured them.This is a book of quackery.
