Thanks so much, MH. I will call about Spray I, II, III and Air Restore. I had bought BF&C a while ago through an herb shop for something else (dental-related) in this area and was very surprised to see that even though it's dr. christopher's formula (supposedly) they have taken out comfrey without mentioning it. It's made by Nature's way. I just double-checked, and yes, comfrey is missing I just looked at their "proprietary blend" and they only have white oak (bark), gravel (root), marshmallow (root), mullein (leafe, lback walnut (hull), slippery elm (bark), calendula (flower) and skullcap (stem, leaf, fruit). I hope I can get comfrey separately for both of my needs. The bottle says "Bone, Flesh and Cartilage" and "formerly BF&C". Obviously comfrey is just too powerful for the consciousness of the American public and must be suppressed.
