I know of no herbal remedies for allergies. The only "herbal" cure I know of is that when my Dad was a kid and his asthma was acting up, they'd make skunk cabbage tea for him - mainly to breathe the steam. Bleeaaaagh. Yuuuuck. (p.S. I swear most asthma meds are based on something similar - they all taste evil.)

I take allergy meds, and they work. I am not drowsy, don't feel "doped up" or anything - but I CAN breathe through my nose. I know they are "drugs" but they are also tested and proven safe in most cases for most people, which ain't true for many herbal "cures."

Air filters, a HEPA-filter vacuum cleaner on all rugs once a day, clean doggies - all these things'll help. Has she had her allergies tested ever?
