Our bodies do have great healing powers but cannot heal every injury, condition or disease unfortunately. There are many anecdotal stories about complementary therapies and people going into remission but they are just that...anecdotal. Some of us will go into true remission (no meds, no symptoms) and will stay there. There is no way to know if you are truly healed or just in temporary remission.
Lupus is a powerful disease and usually requires using modern meds to suppress your immune response. I had a life threatening case complicated with polymyositis and did not have the luxury of fooling around. If you have nutrient dificiencies, a poor diet, a sedentary life style, all of those things should be addressed but that is not treating the problem of an AI disease directly. It helps but does not change your immune response except in some specific situations.
I went from quadriplegic to functional to active again by taking PT and exercise to the limit but it was a modern treatment that saved my life by controlling my immune system and giving me the time to recover. Despite that, I am nowhere near the physcial person I was 7 years ago due to age and significant loss of muscle cells (polymyositis).
Here is an article from the AARP magazine a few years ago about healing.
