I would be dead a long time ago without holistic medicine, and for me it worked for chronic issues as well.
The problem with people for whom holistic approach does not work is that they expect that they should be fixed as cars (pay money to the mechanic, he will do the whole job, so car can be driven again up till the moment something gets wrong. But who cares? Mechanic will fix the problem for money again.) what is certainly not the case in healing.
Holistic approach to the health requires that ill person also gets personally involved in the process of self-healing and is willing to understand that behind every chronic condition is psychological cause and/or unhealthy style of life that leads to the disease.
For me and many other people holistic medicine is excellent and it always works!
