After taking an antibiotic I had a sore in the corner of my mouth that would not heal. The condition is called Angular Chelitis. It is like a paper cut. Apparently it caused by an overgrowth of yeast in the body. It is very common to take an antibiotic and end up with a yeast infection.
I had used a similar product 40 years ago when my children were little for cancer sores. Their ped's doc recommended it. Bottom Line, I took the Floranex for 2 days as directed and the sore healed. I know these sores are a common thing that happen and even the pharmacist didn't push this product. The price is right and the results are almost like magic.
