Essiac dosage - it is confusing

I see where the confusion might come in regarding dosage of Essiac tea.  The books I have and many of the sites say that one ounce of the four herb combination makes 32 ounces of tea.  Then, after having brewed it and storing at that strength, they say to take one ounce of the tea and mix it with two ounces of warm water.  So, that would total 3 ounces of fluid.  I saw one site selling Essiac which claimed that their one ounce of the herb makes 72 ounces of the tea.  That's confusing.  I'd stick to the original formula of making 32 ounces of tea to an ounce of the four herb combination, and then diluting it at ingestion time with an additional two ounces of water.  That way you would conform to its original usage.
