The BF&C is still very effective in healing, but, I feel, when you are dealing with bone issues, you still need the comfrey. My mother was able to completely reverse her osteoporosis, get out of bed and lead an active life again. I would probably be giving her the 5 BF&C every couple of hours, instead of just 4 times per day. When you're trying to break free of the "take 2 and call me in the morning" mindset, 20 capsules per day seems like alot. However, years later when my son shattered his elbow, I gave him 10 BF&C capsules every hour and six Vitalerb capsules on the half hour thoughout the day for 10 days, so he was actually getting 100 BF&C capsules and 60 Vitalerb capsules per day. He had a serious injury and needed serious help - when he was taking the herbs, he didn't need pain killers - when we skipped the herbs, he would beg for pain killers. His experience taught me that pain is the body's cry for help - when you give it what it needs, it stops screaming.
Sounds like you're off to a good start for a complete healing - congratualtions!
