This book actually sounds very interesting. I think I will pick it up. I usually don't brew my herbs, but use them in pouches and pillows. You learn something new every day though right?
This probably sounds pokey but have you tried eBay? Word of mouth helps good too if you have some customers recommending it. Another option is
www.witchschool.com. All the witches you will ever need!
Good luck and best wishes...
