Hello, and thank you for the great question.
Numerous studies have been conducted on marijuana and its active components. While not entirely conclusive, the research on marijuana shows promise for people with PD.
For PD, marijuana is thought to provide numerous benefits, including:
better quality of sleep
improved overall mood
more ease in movement
Despite the potential benefits of marijuana for people with Parkinson’s, there are also some risk factors involved. THC in marijuana can cause:
impaired thinking and movements
So when considering the above, it becomes clear that most of the positive effects cannabis has on PD derives from CBD (cannabidiol), whereas most of the possible adverse effects are derived from THC. As such, I would recommend that you seek "high cbd strains."
ACDC is a hybrid strain that I have touted for several conditions which would benefit from a high CBD and low THC content. The cannabinoid content is extremely CBD-dominant, sitting on average at 20:1 in its CBD/THC ratio. An imperceptible amount of THC makes ACDC an outstanding companion for daily medicinal cannabis. ACDC would be my top overall recommendation as treatment for the symptoms of Parkinson’s disease.
A sativa strain I also recommend is Harlequin. Harlequin is one of the most popular CBD strains available. Typically testing around the 5:2 CBD/THC ratio, it exhibits a sativa-dominant alertness with only mild euphoria.
For sleep time, a CBD heavy indica strain such as Sweet and Sour Widow would be a good choice.
