73% of all statistics are made up. I don't believe in homeopathy but at least the " cures" are harmless unlike our " normal" profit driven health care system which IMO is more worthy of our scorn.
There is plenty of literature out there documenting adverse effects from the use of homeopathic preparations, sometimes severe. Even though these are dilute preparations, some toxins are active at quite low doses.
The biggest harm with homeopathy comes more from patients stopping, or overlooking, conventional treatments, which are generally quite effective, and seeking homeopathic treatment instead. This will often lead to patients getting sicker. And with communicable diseases, this can lead to unnecessary spread of infection.
