Why do we ingest poisons to strengthen our body?

A Canadian class-action lawsuit has been launched against Pfizer Inc. alleging that its arthritis drug Celebrex caused cardiovascular side effects, the law firm launching the suit said Friday."Merchant Law Group included Pfizer's Bextra in its suit and also named Boehringer Ingelheim, Germany's largest pharmaceutical firm, for its Mobicox, in the same class of drugs.

So why do we put these pills into our body? Why do we continue to take the pills until they are proven horribly awful for our health, and then we take the next, newest pill?

Is it possible that the solutions to our health issues may go beyond the answers that are available in a simple bottle?
