Dr. Cheung recommends homeopathic medicines to his patients. There is no scientific evidence or widely accepted theory to suggest that homeopathic medicines work, and Dr. Cheung doesn't believe them to. He recommends homeopathic medicine to people with mild and non-specific symptoms such as fatigue, headaches and muscle aches, because he believes that it will do no harm, but will give them reassurance. Consider the ethical problems that Dr. Cheung's behaviour might pose. Discuss these issues with the interviewer.
