Hmm I don't know, I've been thinking about it for a long time now and nothing comes to mind. The red ring around my mouth appears as soon as I eat ANY MEAL - It has been going on for 6 months now, I have tried cutting out foods, changing my diet completely and still to no avail, it appears after I eat. It was strange that it happened after an enema, it made me wonder what it could be linked to - either my liver because of the coffee, or just candida in my gut?
