I'd disagree Andy. I don't believe in generalisation. You may be right and it's nothing but placebo, but if it works for someone, why not?

Also some herbs/plants (for example, turmeric used in Indian cooking and eucalyptus) have antiseptic qualities. If they can be used to cure ailments without the side effects of modern drugs why not use them?

Also diets play a huge part, but I'm not sure if that comes under homoeopathy.
