Several papers have been published on Essiac in the last few years and are worth noting..
One in particular is important because it suggests that using Essiac may be dangerous for patients with breast cancer.
They were able to demonstrate some anti-cancer effect from these products but only at very strong concentrations.
Often the cells needed to be bathed in a 1/10 dilution of the tea to see any effect.
Two papers are about Essiac and prostate cancer and are positive.
In August 2004, the Journal of Alternative and Complementary Medicine published a test tube study that showed that Essiac might inhibit prostate tumor cell growth.
In fact, high levels of i NOS increases the risk of getting breast cancer from radiation exposure by seven fold.
[vii] [viii] When looking at herbal extracts it is nice if they work in vitro.
That is, you add a little of the herbal extract into a test tube filled with cancer cells and some or all of the cancer cells drop dead.
Not all herbs that are useful for cancer patients do this.
For other types of cancer, there is little encouraging research and for breast cancer, these results argue against using Essiac.
