I've been using Nettle leaf and many of the other Tonic herbs you recommend for adrenals and they have helped stop the runny nose and sneezing a lot. But i'm thinking the other part of my issue, the sinus pressure, has to do with a issue with my respitory system.
I will give watercress a try. Are their any other herbs you'd recommend with watercress that can help clear the sinus/respitory? I found this site that talks about some but i'd like to get your thoughts on them: http://evenstaronline.com/articles/respiratoryease.html
It seems like many of them talk about clearing coughs, I never have a cough but i guess their very closely related, it just effects my nasal instead.
