CBC's Marketplace examines homeopathy in the Jan. 14, 2011, episode.
Homeopathic remedies take an ingredient — from a plant, animal or mineral — and dilute it repeatedly with water. The theory is that water retains the memory of the original ingredient. Practitioners say the more dilutions there are, the stronger the remedy.
Critics say homeopathic treatments do nothing, putting people in danger as they delay getting conventional medical treatments. Supporters counter that it works on everything from headaches to cancer, even if they can't explain why.
CBC asked a chemist with the University of Toronto to analyze two popular homeopathic remedies. Watch the full Marketplace investigation to see the results.
