Herbs

So I also would like to learn about herbs. I really want the book "A green witch's herbal" by Silja. I tend to want to learn about a lot of things at once so I'm having trouble picking just one. I currently am trying to learn, Tarot reading, Rune reading, my Pendulum and now herbs. Such a full plate. I have a divination notebook, which I need to rearrange so I can add a section for Pendulum studies. My Herbal notebook is currently M.I.A. so I have to find it or get another one. I'm using it for Herbs, Stones and Crystals. I really need to just pick one thing and work on it but its so hard lol Below is he amazon link to the book I want.

Prosperity Tea

I tried one of the teas that I have for sale after finally getting a mesh tea ball. It was very good and so far I've made two mugs. We shall see if it actually brings me prosperity...to help it along I've sent in another application and am going up to the store tomorrow to talk to someone.

List of Herbs in the tea:
Black Tea
Pennyroyal
Parsley
Basil
Meadow-sweet
Sage
Clover
Mistletoe
Rosehips

Maybe someone who knows herbs can tell me why mistletoe is included..I thought it was poisonous.
