4 herbs Essiac Tea advice

Good day,

I believe this has been discussed before; however, I would like to seek experienced members here for advice on the following vendors and which sells the original 4 herbs essiac:

Creators Blessing from Allensclub.com (lowest price, uses Turkey Rhubarb)

Health Freedom via essiac-tea.org (mid price, use sheep sorrel roots)

Essiac Canada International via essiac-canada-intl.com and also via essiacfromcanada.com (rhighest price, uses Indian Rhubarb but uses sheep sorrel leaves?)

Regardless of pricings, could experienced members here kindly advise which vendor sells the most reliable and original Essiac blended tea, be it in herbs or powder.

thank you very much

regards/vince
