Since going paleo, I've had little to no seasonal allergies.  Got through
last fall w/o incident.  Amazing because I usually have several weeks of
sinus and upper respiratory problems.  This spring I had a few, mostly
minor, problems with allergies, probably because I ate off-diet a few times
during that time.  Dummy me.  My favorite cure is Quercetin.  The
bioflavonoids exert an antihistaminic-like effect.
