nice flavor, hard to evaluate impact..
tastes and looks like roast coffee (or a chicory blended coffee).  Very subtle fragrance profile.  Unclear how much placebo effect is manifested in these types of products and hard to compare it to impact other teas (blue lotus, or Pukka night time) for me.  All have been equally helpful in mellowing down ( I tend to have calls till 11 pm on most days).  At over a $1.5 per serving, will be part of the rotation if I see a significant improvement over my other teas.  After a week of use, seems promising.  But need to see if the body adapts and the effect just peters away.  Blue lotus has been so far the best for me.
