The best strains for Multiple Sclerosis are equal THC-CBD strains (HYBRID).
According to the National Multiple Scleoris Society, a “Summary of evidence-based guideline: Complementary and alternative medicine in MS” in 2014, revealed:
Oral cannabis extract and synthetic THC are probably effective for reducing patient-reported symptoms spasticity and pain.
Sativex oral spray (GW Pharmaceuticals) is probably effective for improving patient-reported symptoms of spasticity, pain and urinary frequency. More cannabis research studies are required"
Sativex contains a standardized 1:1 ratio of THC cannabidiol (CBD). Therefore any Hybrid strains or equal THC CBD strains would be ideal according to evidence based practice.
