It's been several years now that I had the PD and used the Violet Extract. It has never returned. I was already on a special diet (gluten free, low dairy) prior to having the PD. In answer to a few of the questions on this board: how to use the violet extract: I just let a couple drops out of the dropper onto my index finger and rubbed it on the rash around the mouth and bottom corners of nose. It is brown in color and might temporarily stain the skin where the rash is but dissipates right away. It has a slight odor to it but it was not very strong. Good look to all with this !
