you can buy the BF&C Tea at
http://www.mhdewormer.com
You can see the list ingredients at obeynature.com on the formulas page or at mhdewormer.com, not really a recipe though. I think you would need to consult one of Dr. Christopher's books for the recipe.
How often you take would depend on what you are taking it for I believe. There are many ways to use the BF&C formula.
