As USA Today reports, many American consumers cite distrust of big pharmaceutical companies as one of the main reasons they lean towards using traditional therapies. But a new book by Paul Offit, chief of infectious disease at the Children’s Hospital of Philadelphia, argues that the alternative medicine industry is just as focused on profit and business as it is on healing.

In his book, Offit paints a picture of an aggressive, $34 billion a year industry whose key players are adept at using lawsuits, lobbyists and legislation to protect their market.
