While Brother may well ultimately right re the placebo effect and homeopathy, I did experience some difference with it compared to other things. When I tried processed supplements, I would feel a slight placebo-like effect which was very minor, for up to 24 hours afterwards before stopping, but there was no significant benefit in any particular symptom. Aajonus, however, suggested that something else was at work, though, that the supplements were stimulating peoples' adrenals, giving them a false temporary "feel-good effect".
We have had good result with homeopath, the biggest issue i had with homeopath is "how can it solve a problem longterm without a change in lifestyle".
My answer to that is "use homeopathy to resolve your symptoms quickly (short term) change lifestyle (raw whole foods, sleep habit, meditation) for long term solution. Without the second part the first would stop working quickly. Also i believe homeopathy is a energy medicine.
I know a good homeopathy doctor, that is effective, short term.
