Sorry that this is not the timliest reply...
I have used Essiac tea with amazing success for a variety of ills.
I used it for myself to alleviate the detrimental effects of anemia, I used it on a sick cat with the side effect of it CURING his diabetes, I have friends who used it to fight cancer on themselves and on their pets, as well.
I bought it locally at an organic grocery- it is made by Frontier Herbs under the name of "Angel Tea." A little goes a long way... it is practically dirt cheap if you buy it in the powder/dried form (as opposed to the liquid) and would be easy to ship. There are boiling instructions here:
Good luck to you and your friends!
