You might also want to put this question on Dennis Hardy and Ask Barefoot's forum.
There is a product (herbs) BF&C and that helps with healing and rebuilding.
Of course I have a history since Feb'03 of doing a lot of cleansing and change of lifestyle, but this year I used a whole bottle of it, 3x a day for spinal stenosis in the lower back and so far my back has been fine. I am planning to repeat it in a few months.
Read up on it on Ask Barefoot's site, I think it is under Testemonials or My Teachers (Christofer).
