Boron is in apples. Yttrium is in cherries and red beets. Supplementing with organic apple cider vinegar [with the mother] contains the good bacteria that are supported by environment with boron [yttrium?] in it. Put it on a red beet salad.

In addition to its excellent potassium supply, apple cider vinegar also contains trace minerals including calcium, magnesium, phosphorus, boron, - all important in the formation and maintenance of strong, dense bone structure. Add sulphur to the list too."
It seems to me that while knocking out the bad bacteria [with MMS] that lives off the aluminum that competes with the yttrium in the intestines, supplementing with ACV with the mother is the best way to help relieve parkinson's symptoms.
