Hi
I wonder if you've tried tracking down the various types of rice like sastika, sali, raktasali, mahasali, or kalama. I think my main grains should be barley (best for general equilibrium) and Job's Tears (nothing better for losing weight — both according to Caraka — though I eat 'em less since I've started to like red rice. I find it strange that sali and sastika are mostly used in the chapter on rasayanas though I haven't looked carefully read Caraka enough to figure out why. But worth a try it seems if they can be found.
