PN, for relief of spasticity, pick any hybrid strain that is high in Indica versus Sativa.
Strains high in Indica produce more of a body high (muscle relaxation) than a head high (psychoactive). Strains high in Sativa produce more of a head high than a body high. It's almost impossible to find marijuana that is 100% pure Indica or Sativa, but it's relatively easy to find hybrid strains, such as one that is 80% Indica/20%Sativa. There are hundreds, if not thousands, of hybrid strains.
Take a look at the different amounts of Indica and Sativa in these mj seeds: http://amsterdammarijuanaseeds.com/seed ... ized-seeds
