No clue.

With herbs, your dose is determined on the effect your looking for. Dr. Christopher used HUGE DOSES and when the patient through up, he said GREAT, now there is room for more! I have seen this and can understand why he wrote that.

The BF&C is very safe in my opinion, as long as you make use fo the Lower Bowel Balance formula first and durring, otherwise go slow and take a few droppers of tincture and 1-3 capsules 3X daily as starter.
