Hi Teresa
Can I suggest you take a look at Matthew Wood's writings on Agrimony. You can find them
http://www.naturasophia.com/Agrimony.html and
http://books.google.co.uk/books?id=MstkfhSd4FMC&pg=PA85&lpg=PA85&dq=Matthew+wood+agrimony&source=bl&ots=vqxirvg6oD&sig=gEeghDuoQdl451AHsRuWw-6oXaA&hl=en&ei=xmf1S8OTIeWTsQapkZSfBg&sa=X&oi=book_result&ct=result&resnum=3&ved=0CB0Q6AEwAg#v=onepage&q&f=false Brigitte has also written a blog post about agrimony as part of the UK Herbarium blog party on
http://www.myherbcorner.com/blog/?tag=agrimony
I don't use agrimony a great deal but I make tincture from my plants and the flowers are always popular for flower remedies during workshops.
I hope you find something useful.
Best wishes
Sarah
