Hi. I just read, in the 9/21-22 PD Digest, a subscriber's observation that Oil of Wintergreen, when sniffed, seemed to diminish dyskinesia. A member of my family has PD and I think that I may suggest this to her. It would be my guess (as a layman) that there might be information about this use of Oil of Wintergreen -- or at least information about the basic biochemical processes that may possibly be involved -- in resources dealing with the field of "Aroma Therapy". Perhaps holistic practitioners, or running an internet informational search (via one of the major search-engines, such as Altavista.com or Yahoo.com, for instance) might turn up or spur some valuable clues on this matter. -- SJS
