That is very valid my friend though it might sound ridiculous.Garlic is very good and has many benefits in the human body when consumed. As much as it is a cooking ingredient, it is also a medicinal. The main ingredient in garlic is allicin which has antibacterial, antivirus, antifungal and antioxidant properties. Now yeast infection is caused by a fungus called Candida. It is a natural flora of the vagina but causes problem when there's overgrowth of it. Looking at the properties of garlic, you can see that it has the ability to attack the overflow of this yeast. It is used by neatly peeling a single clove and threading It much like a tampon. Afterwards if is carefully inserted into the vagina and left there for at least 8-12 hours. The thread is for easy retrieval. This is done everyday until symptoms disappear. I tried that after all the over the counter meds failed and it worked magic.
