Legally, because of the controversy over comfrey, we have to state on our label that FissureHeal is not for use by pregnant or breastfeeding women, and that’s our official answer.
However, please keep in mind that as the comfrey is in the rectum only, it does not go through the digestive system.
Also, I can tell you that Jini Patel Thompson – the formulator of FissureHeal – used it when needed whilst both pregnant and breastfeeding (she has 3 kids) with no ill effects. Obviously, this in anecdotal evidence only.
For safe usage guidelines, please consult your naturopathic doctor for his/her opinion (or a herbalist).
