CS advice about how to treat Parkinson?

I have a friend who has parkinson, he is around 68 years old and was diagnosed a year ago. In his youth he made jewelery and used led in his production, and he say that is
the reason he got sick now with parkson, that he inhaled led when he was younger.

He takes melatonin and it helps. His doctor would not prescribe it so he bought it on the net. He also takes omega3's fishoil. What else can he do?

Parkinson's requires individualized treatment, because there are many forms of "Parkinsonisms."

Most patients have disruptions in their gut-brain axis, and also have iron overload in the brain.

If the brain stem is not properly aligned it can signal or alter the microbiota to be directed towards a more inflammatory state. Then there is polymorphisms in some cases (MTHFr), in others there is a histamine (Mass cell disease) problem, or there is a defect in the 8 steps of processing heme. Then there's oral pathology (root canals, cavitations), presence of lyme, etc.

I personally would try liposomal or nebulized glutathione, earthing-grounding and/or PEMF started at a very low-level of intensity.

Search on Youtube and you will find several before and after Parkinson's treated with IV glutathione and PEMF videos.
