Well, I don't use the term shaman, (partially due to cultural concerns personally, but no worries for anyone who DOES use that term. Your choice, go for it!

) but I ascribe to the Wise Woman Way and have attended a workshop or two with Susun, plus read her books. I consider myself just "herbalist" or Sorta-kinda-wise in-training Human.

Welcome, by the way to the forum, it's a great resource here!
As for more resources, I would definitely seek out Jim McDonald also:
http://herbcraft.org/articleindex.htmlPerhaps the Gallagher family (with an active Herbal Dad)
http://learningherbs.com/about/Probably plenty of other sources folks here can suggest in another thread?
Welcome & Green Blessings!
