Harlequin (11.6% CBD - 8.4% THC) and Cannatonic (8.1% CBD and 6.9% THC) are two strains that have been around here for a few years now. Both are accepted as good CBD meds. You should be able to track these two down without too many problems.
For high CBD/low THC strains, there is AC/DC ( often mis-named "Charlottes Web" ) which has tested out at 19% CBD and 0.5% THC. The anti-inflammatory properties of this strain are really appealing to me. This one is slowly making it's way to the area. A few folks I know claim to have it, but that is worthless without testing. This strain is highly recommended for cancer patients.
I know that SourTsunami is local, but I don't know how well it helps. Blue Dynamite is supposed to be good also.
I am currently looking for The Remedy.
I would say that Cannatonic might be what you are looking for. It helps with nausea but I think you need some THC to help increase appetite.
I hope this helps.
