M.H.
WishGarden Herbs makes a powdered cord care product that works wonders. You might try to get ahold of that. It is a natural, herbal product. My dd did not have an unbilibal granuloma, but it dried up her cord and caused it to fall off in about a week--it is a powdered drying product that works super quickly.
This product is made mostly of powdered goldenseal root.
