Ozone Therapy?

My husband does not have a diagnosis yet, just a tremor in his right arm from elbow to finger tips. While waiting for Neurology appointment May 12, 2023, we have gone to see some natural practitioners. One has done Food Sensitivity, DNA, extensive blood work and Heavy Metal Testing. He is suggesting Chelation Therapy for heavy metal, but OZONE THERAPY to clean blood of any infection etc. Treatment is $695 Canadian and suggesting 10 treatments, then retest and if he sees same thing, carry on with treatments 5 - 10 more. Not quite sure what to do. If anyone has tried Ozone Therapy for Temor/Parkinson, please share your results.

Watched a few You Tube videos which explain the treatment plus apparently great results from this. Also, will order a book called Goodbye Parkinson's, Hello life!: The Gyro–Kinetic Method for Eliminating Symptoms and Reclaiming Your Good Health plus try the dance exercise on You Tube by Alex Kerten.
