Hi all, I have some comments about some of the herbs I am seeing mentioned. First let me say that in my family virtually every illness, wound etc. is treated either with homeopathy or herbs. We have not used antibiotics or any other allopathic medicines in over ten years. I also teach a course in herbal medicinals at 2 local colleges. I looked up black walnut and it is indeed a fungcide. It is also used as a tea to dry up milk during weaning. It may be prudent to use it sparingly in a lactating breast even externally because of its ability to dry milk secretion. Tea Tree oil is also a wonderful funguscide, however I am not comfortable using it on breasts because it can be toxic. I am awaiting a response from an herbalist regarding its use for nipple yeast. It is also highly astringent. Goldenseal is very good for colds but it is a very powerful herb that is usually not recommended for children. Adults taking it in tincture form are usually cautioned to take it for 7 days only and then stop. The tea can be taken for two weeks. It metabolizes in the liver and toxicity for over use can occur. I do not normally recommend nursing women use this herb. Golden seal is not recommended during pregnancy.

It behooves us all to thoroughly research an herbal remedy before using it or recommending it. My favorite and safest herb for yeast is still Calendula apllied topically. Rita
