There are several objections to using non-pharmaceutical substances for treating Parkinson's. Among these are:- 1. The purity of the substace cannot be guaranted. 2. The concentration of the active ingredient cna be very variable. 3. There has been no double-blind testing (where a substance is supplied to a PWP taking part in a trial of a new mediication. The substancemay be a genuine medication, or a placebo [harmless sujbstitute].) Neither the PWP nor the administering doctor knows which is which. That way, any relief that the person receiving the actual medication feels is liable to be genuine, and not distorted by the desires of either the doctor or the patient. 4. No toxicity testing hsa been done. 5. No testing has been done of the possible side-effects of the substance. 6. No testing has been of the effects of the subatance on other medication. 7. The substance may be illegal, with all that that portends. There is more, but you get the picture. Dr J. F.
