I take rhodiola daily, but I do buy a supplement (from New Chapter, but Gaia Herbs is good, too). It is a great adaptogen, it makes a stressfull day at work or commute much more enjoyable. I grow it as well, but have not yet harvested. I really only grow it to balance my ingestion, but of you are into extracts I suggest a tincture- basic alcohol extration then take a dropper first thing in the morning before work. When my boss is yelling at me I smile inside and think, "hee, hee, this stuff is great AND legal!"
