Im amazed how inexspensive this oil is! Is this oil meant for consumption? Does it taste like the primrose oil in the capsules? I buy Barleens capsules and a bottle of 50 costs me 13.00, I would guess that I might yeild maybe two ounces if I emptied out the capsules and swished. too exspensive of course. Is your primrose oil yellow? any tastes of rancidity? thanks!
