Thanks again. Nettle leaf seems to be a panacea. It is part of my daily regimen. It hasn't helped my sinuses though -yet. I haven't found any of the natural antihistamines to work for me. I will continue to use nettle; especially if it can help through the cedar season. My sinuses are chronically swollen, I think from birth - 61 years ago. That makes them my canary in the mine.
