Robin: re propholactic (sp) yeast treament...I am not sure that there would be dis-advantages...depending on what you are planning to treat with...I recently had an expereice with a mother who had a sizable crater in her nipple. Her Ob called me to discuss my care plan. One of my reccomendations was calendula gel...I explained to him that I like to use it for wound healing as it also contains anti-fungal properties. I assured him that at present I did not susspect yeast overgrowth. He felt that this would be a very positive thing to do considering the situation. .... let us know how it goes....patricia
