My suggestion is to send for my free 108 page booklet I made as a guide for seminars. There you will find all your answers and more.
You can e-mail me a shipping address or write;
Country Baskets
P.O. Box 263
Middleburg, Ohio 43336
I can not send anything herbal out of the U.S., but can send papers such as books.
Eventually I will have a shortended version of this booklet you can down load for free, but it may be a few weeks. For now I can only send a paper copy.
