where to buy Essiac tea

Hi! I need help

For already couple of months I am reading info about Essiac tea. I want to buy it.
And currently I am facing a problem.
As I understood it is a challenge to find trustful supplier of the tea, I found a bulk of them, they offer different products (powder, capsules) for a very different prices.

Could you help with a choice of supplier (preferably European, since I live in Europe) and tell what is better powder or capsules.

Thanks! Tweet
