some folks drink the juice of the 2nd growth; most do not. Many feel
there is not too much energy in the 2nd growth juice. Try it yourself
and see how you feel. Many feel allergic to drinking wheatgrass
juice at all. See how you feel, and watch and see how others feel.
Overall, the "problem" of allergic reactions seems to be caused by the
mold; and just spraying wheatgrass with hydrogen peroxide SHOULD solve
the problem by handling the mold; but, sometimes it doesn't. Then,
one could grow wheatgrass outdoors so that the direct sunlight itself
seems to take care of the mold, and create very positive wheatgrass
juice.
