Stick with the olive oil...the general consensus here seems to be...cold OR expeller pressed(some seeds cannot be effectively cold pressed), organic. Do not use canola..do not use generic "vegetable" oils.
Folks here have used sunflower, sesame, olive, coconut, hemp, flax, Voodoo Love Root(just kidding!), evening primrose...
We've also found that it's good to change oils on a regular basis...so swish & switch on!
Welcome to the light, Killuminati. Lurk no more! :)
