So methylene blue actually does something? I was researching a lot of this stuff for my 60year old father. He recently experienced a psychotic episode. But now it turns out he actually has neurological damage (already sclerotic), most likely beginning of dementia. The doctor prescribed donepezil (aricept) and I give him some supplements: coconut oil, turmeric, alcar, b-vitamins, lecithin, omega 3. Now I'm trying to get my hands on Montelukast (asthma drug, needs prescription) and MB.
