I don't take it as a challenge (or in any negative way), I admire people that seek the truth diligently :)
All you have to do to know what I'm saying is true is to read the works of Dr. Christopher (unedited versions), listen to his herbal lectures (audio CDs) or find a set of the original VHS tapes of his only recorded lecture/s (that are both audio/video) during a class at his School of Natural Healing. HIS personal formulas (not those of others) were ALWAYS*** given/written as "parts".
***There are occasions (for example, when instructing how to make teas/decoctions/salvees) that he will give a certain measurement of herb in 'ounces' and then the water/fluid/oil in fluid ounces. But other than those, when listening to the words of Dr. Christopher directly from his mouth, you will clearly hear all herbal formulas given in parts.
If you are interested in finding his 'complete works' or the Herbal Lectures (10 cd set), please email me at firstname.lastname@example.org and I'll give you some assistance. I just posted a link to a set of the videos/VHS that are now available from a seller on eBay.
