If you can get hold of it, i think Matanuska Tundra has quite a few medicinal uses... its from up in the mountains, its easy to harvest at the right time too, it tastes like chocolate, and is highly recommended..

as for indica, 'Mangolian Indica' or 'Slyder' both seem like some good stuff, especially for growing

whatever happens i hope ur gran is okay weed should help her out
