A question about hyssop... [View all]

My daughter has a hyssop plant that she uses for ritual purposes I think. I'd like to learn a bit more about it, its uses, and how to prepare any oils or extracts this group might know about. So far my only support has been to dry it and make it available for use in herb tea etc. I know it has some medicinal purposes, but that it can also be poisonous if over done. Any help or suggestions would be appreciated.
