I am far from an expert on Parkinson but it would seem to me that making edibles out of a strong indica would probably suppress tremors. For me edibles rock me way more than smoking as far as relaxing me. Arora indica or something like papaya would fit the bill but remember that each strain effects each person differently. I hope this helps!
