Podee, it is recommended to drink 1 oz a day, with 2 ounces distilled water, for general health and preventing colds and the flu. I know some folks, including us, who are doing that. Will have to let you know after the cold/flu season how it worked for us. Last year, in lieu of the flu shot, my husband and I took Thymex by Standard Process and also bought some for our friends (she is allergic to the eggs used to make the flu vaccine and he had just had surgery on his neck for a damaged disc). I caught a 3-day cold when I ran out of the Thymex and had to wait 10 days to get some more, but none of the others did. I didn't learn about the Thymex until well into the cold flu season, next time I would begin to take it much earlier in the season, say in October. My friend works in an office with several other people and she was the only one who didn't get sick, which made her very happy.
Just remembered that the man who was healed of cancer said he continues to drink 2 oz a day and he has never had another cold or the flu since he was healed. The woman with the non-hodgkins lymphoma had been drinking the tea for 2 months when she was retested for blood results. I'm waiting to hear more about how she's doing after more time goes by.
Remember, Essiac is not plain tea, but herbs, and they should be taken only as directed because of their potency. I don't know that the man was completely healed in 6 weeks, but more so that as time went by his diagnosis was reversed and eventually he was completely healed. We both know that healing is a process and takes time to accomplish completely.
Why not put it to the test for yourself?
Here's to your healh.
