Possibly my favorite indica, Dark Star gives me the pleasure of peace.  Descended from Purple Kush, something I’ve yet to try, the anxiety relief in this particular strain is akin to good yoga.  As a matter of fact, this is one of the indicas that keeps me clear-headed enough to do yoga, something I can usually only accomplish with at least 50% sativa in my system.  I pull out this strain when I have something to celebrate.
