A simple question, therapy should be divided into meaningful or false:
Let's assume that every healing is a Self-healing, we just need to see if a treatment allows this or not ..?
There are a lot of "2nd-best" therapies left that allow the best (self-healing).
Homeopathy is involved, TCM, and much more ... but not conventional medicine.
Advantage of conventional medicine: it may suppress conditions..this may sometimes be necessary to save lifes- but if you use it too often and if you think it is the only way it is as useful as a hole in the head...
