A conscientious alternative medicine practitioner should never suggest homeopathy as an alternative to scientifically proven drugs. If these treatments are recommended, they should only be used to complement the proven treatments. In these cases where it has been selected by a medical professional, the fault is not with the treatment, but in the misleading and dangerous behaviour of the human therapist.
The issue of alternative medicine interfering with conventional medical practices is minimized when it is turned to only after conventional treatments have been exhausted.
A conscientious alternative therapist would never suggest their treatment as an alternative to traditional medicine for a serious condition.
