I was researching seeds and found some info on a strain with genetics from Japan called Japanese Shiatsu Kush. It's supposed to be great for chronic pain. heres a lil copy and paste:a strain developed on the island of Amami Ōshima - bred specifically to target the shiatsu regions of the body. Having previously never left the shores of Japan, these special genetics are now available for worldwide release. Winner of the Gold Medal at the underground JCA Awards, this exotic strain has particular medical benefits to those suffering chronic pain by way of releasing all stresses and tension.
